Properties of green coffee

Commercial drum type coffee roaster

The sound of a coffee roaster.

Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.

The vast majority of coffee is roasted commercially on a large scale, but small-scale commercial roasting has grown significantly with the trend toward “single-origin” coffees served at specialty shops. Some coffee drinkers even roast coffee at home as a hobby in order to both experiment with the flavor profile of the beans and ensure the freshest possible roast.

The first recorded implements for roasting coffee beans were thin pans made from metal or porcelain, used in the 15th century in the Ottoman Empire and Greater Persia. In the 19th century, various patents were awarded in the U.S. and Europe for commercial roasters, to allow for large batches of coffee. In the 1950s just as instant coffee was becoming a popular coffee drink, speciality coffee-houses began opening to cater to the connoisseur, offering a more traditionally brewed beverage. In the 1970s, more speciality coffee houses were founded, ones that offered a variety of roasts and beans from around the world. In the 1980s and 1990s, the gourmet coffee industry experienced great growth. This trend continued into the 21st Century.

The first known implements for roasting coffee beans were thin, circular, often perforated pans made from metal or porcelain, used in the 15th century in the Ottoman Empire and Greater Persia. This type of shallow, dished pan was equipped with a long handle so that it could be held over a brazier (a container of hot coals) until the coffee was roasted. The beans were stirred with a slender spoon. Only a small amount of beans could be heated at one time. The first cylinder roaster with a crank to keep the beans in motion appeared in Cairo around 1650. It was made of metal, most commonly tinned copper or cast iron, and was held over a brazier or open fire. French, Dutch and Italian variations of this design quickly appeared. These proved popular over the next century in Europe, England and the American colonies.

In the 19th century, various patents were awarded in the U.S. and Europe for commercial roasters, to allow for large batches of coffee. Nevertheless, home roasting continued to be popular. A man working at a commercial roasting plant beginning in the 1850s in St. Louis, Missouri, said that “selling roasted coffee was up-hill work, as everyone roasted coffee in the kitchen oven.” Appliances catering to the home roaster were developed; in 1849 a spherical coffee roaster was invented in Cincinnati, Ohio, for use on the top of a wood-fired kitchen stove, fitted into a burner opening. Green beans were available at the local general store, or even through mail order. For roasting, many people used such simple methods as a layer of beans on a metal sheet in the oven, or beans stirred in a cast iron skillet over a fire. Despite the wide popularity of home roasting, Burns felt that it would soon disappear because of the great strides made in commercial roasting in the 1860s and 1870s, including the benefits of the economies of scale. The commercial roaster inventions patented by Burns revolutionized the U.S. roasting industry, much like the innovations of inventors in Emmerich am Rhein greatly advanced commercial coffee roasting in Germany. As well, the 1864 marketing breakthrough of the Arbuckle Brothers in Philadelphia, introducing the convenient one-pound (0.45 kg) paper bag of roasted coffee, brought success and imitators. From that time commercially roasted coffee grew in popularity until it gradually overtook home roasting during the 1900s in America. In 1903 and 1906 the first electric roasters were patented in the U.S. and Germany, respectively; these commercial devices eliminated the problem of smoke or fuel vapor imparting a bad taste to the coffee. In France, the home roaster did not yield to the commercial roaster until after the 1920s, especially in rural areas. Coffee was roasted to a dark color in small batches at home and by shopkeepers, using a variety of appliances including ones with a rotating cylinder of glass, sheet iron or wire mesh, and ones driven by hand, clockwork or electric motor. Because of the smoke and blowing chaff, country dwellers generally roasted outdoors.

In the 1950s just as instant coffee was becoming a popular coffee drink, speciality coffee-houses began opening to cater to the connoisseur, offering a more traditionally brewed beverage. In the 1970s, more speciality coffee houses were founded, ones that offered a variety of roasts and beans from around the world. In the 1980s and 1990s, the gourmet coffee industry experienced great growth. Through the 1970s and 1980s, the Siemens Sirocco home roaster was made in West Germany and marketed globally. It was a small fluid-bed roaster made for the home enthusiast. The product was named after a commercial hot-air roasting process which itself was named after the hot Sahara winds called sirocco. In 1976, chemical engineer Michael Sivetz patented a competing hot air design for manufacture in the U.S.; this became popular as an economical alternative. Sivetz called for the home roaster to focus on the quality of the bean. From 1986 through 1999 there was a surge in the number of patents filed for home roasting appliances. In the 1990s, more electric home roasting equipment became available, including drum roasters, and variations on the fluid-bed roaster. By 2001, gourmet coffee aficionados were using the internet to purchase green estate-grown beans for delivery by mail.


The coffee-roasting process follows coffee processing and precedes coffee brewing. It consists essentially of sorting, roasting, cooling, and packaging but can also include grinding in larger-scale roasting houses. In larger operations, bags of green coffee beans are hand- or machine-opened, dumped into a hopper, and screened to remove debris. The green beans are then weighed and transferred by belt or pneumatic conveyor to storage hoppers. From the storage hoppers, the green beans are conveyed to the roaster. Initially, the process is endothermic (absorbing heat), but at around 175 °C (347 °F) it becomes exothermic (giving off heat). For the roaster, this means that the beans are heating themselves and an adjustment of the roaster’s heat source might be required. At the end of the roasting cycle, the roasted beans are dumped from the roasting chamber and air cooled with a draft inducer.

During the roasting process, coffee beans tend to go through a weight loss of about 28% due to the loss of water and volatile compounds. Although the beans experience a weight loss, the size of the beans are doubled after the roasting process due to the release of carbon dioxide, release of volatile compounds, and water vaporization.

In Vietnam coffee is often coated with oil (traditionally clarified butter) and a small amount of sugar prior to roasting to produce a “butter roast”. The roasting process results in an additional caramelized coating on the beans.


Diedrich infrared drum machine: One of the most common roasters used to roast coffee beans.

The most common roasting machines are of two basic types: drum and hot-air, although there are others including packed-bed, tangential and centrifugal roasters. Roasters can operate in either batch or continuous modes. Home roasters are also available.

Drum machines consist of horizontal rotating drums that tumble the green coffee beans in a heated environment. The heat source can be supplied by natural gas, liquefied petroleum gas (LPG), electricity, or even wood. The most common employ indirectly heated drums where the heat source is under the drum. Direct-fired roasters are roasters in which a flame contacts the beans inside the drum; very few of these machines are still in operation.

Fluid bed or hot-air roasters force heated air through a screen or perforated plate under the coffee beans with sufficient force to lift the beans. Heat is transferred to the beans as they tumble and circulate within this fluidized bed.

Some coffee roasters use names for the various degrees of roast, such as “city roast” and “French roast”, for the internal bean temperatures found during roasting. Recipes known as “roast profiles” indicate how to achieve flavor characteristics. Any number of factors may help a person determine the best profile to use, such as the coffee’s origin, variety, processing method, moisture content, bean density, or desired flavor characteristics. A roast profile can be presented as a graph showing time on one axis and temperature on the other, which can be recorded manually or using computer software and data loggers linked to temperature probes inside various parts of the roaster.

The most popular, but probably the least accurate, method of determining the degree of roast is to judge the bean’s color by eye (the exception to this is using a spectrophotometer to measure the ground coffee reflectance under infrared light and comparing it to standards such as the Agtron scale). As the coffee absorbs heat, the color shifts to yellow and then to increasingly darker shades of brown. During the later stages of roasting, oils appear on the surface of the bean. The roast will continue to darken until it is removed from the heat source. Coffee also darkens as it ages, making color alone a poor roast determinant. Most roasters use a combination of temperature, smell, color, and sound to monitor the roasting process.

Sound is a good indicator of temperature during roasting. There are two temperature thresholds called “cracks” that roasters listen for. At approximately 196 °C (385 °F), the coffee will emit a cracking sound. This point is referred to as “first crack,” marking the beginnings of a “light roast”. At first crack, a large amount of the coffee’s moisture has been evaporated and the beans will increase in size. When the coffee reaches approximately 224 °C (435 °F), it emits a “second crack”, this sound represents the structure of the coffee starting to collapse. If the roast is allowed to progress further, the coffee will soon fully carbonize, and eventually combust.

These images depict samples taken from the same batch of a typical Brazilian green coffee at various bean temperatures with their subjective roast names and descriptions.

22 °C (72 °F), Green Beans

Green coffee as it arrives at the dock. The beans can be stored for approximately 12–18 months in a climate controlled environment before quality loss is noticeable.

165 °C (329 °F), Drying Phase

During the drying phase the beans are undergoing an endothermic process until their moisture content is evaporated, signifying first crack.

196 °C (385 °F), Cinnamon Roast

A very light roast level which is immediately at first crack. Sweetness is underdeveloped, with prominent toasted grain, grassy flavors, and sharp acidity prominent.

205 °C (401 °F), New England Roast

Moderate light brown, but still mottled in appearance. A preferred roast for some specialty roasters, highlights origin characteristics as well as complex acidity.

210 °C (410 °F), American Roast

Medium light brown, developed during first crack. Acidity is slightly muted, but origin character is still preserved.

219 °C (426 °F), City Roast

Medium brown, common for most specialty coffee. Good for tasting origin character, although roast character is noticeable.

225 °C (437 °F), Full City Roast

Medium dark brown with occasional oil sheen, roast character is prominent. At the beginning of second crack.

230 °C (446 °F), Vienna Roast

Moderate dark brown with light surface oil, more bittersweet, caramel flavor, acidity muted. In the middle of second crack. Any origin characteristics have become eclipsed by roast at this level.

240 °C (464 °F), French Roast

Dark brown, shiny with oil, burnt undertones, acidity diminished. At the end of second crack. Roast character is dominant, none of the inherent aroma or flavors of the coffee remain.

245 °C (473 °F), Italian Roast

Nearly black and shiny, burnt tones become more distinct, acidity nearly eliminated, thin body.


At lighter roasts, the coffee will exhibit more of its “origin character”—the flavors created by its variety, processing, altitude, soil content, and weather conditions in the location where it was grown. As the beans darken to a deep brown, the origin flavors of the bean are eclipsed by the flavors created by the roasting process itself. At darker roasts, the “roast flavor” is so dominant that it can be difficult to distinguish the origin of the beans used in the roast.

Below, roast levels and their respective flavors are described. These are qualitative descriptions, and thus subjective.

Cinnamon Roast, American Roast, New England Roast, Half City Roast, Moderate-Light Roast After several minutes the beans pop or crack and visibly expand in size. This stage is called first crack. Dry Lighter-bodied, higher acidity, no obvious roast flavor. This level of roast is ideal for tasting the full origin character of the coffee.
City roast, City+ Roast, Full City Roast After being developed through first crack, the coffee reaches these roast levels. Dry Sugars have been further caramelized, and acidity has been muted. This results in coffee with higher body, but some roast flavor imposed.
Full City+ Roast, Italian Roast, Vienna Roast, French Roast After a few more minutes the beans begin popping again, and oils rise to the surface. This is called second crack. Shiny. The level of oil correlates to how far the coffee is taken past second crack. Bittersweet flavors are prominent, aromas and flavors of roast become clearly evident. Little, if any, origin character remains.

When describing the taste of coffee, the 3 tier coffee flavor tasters wheel is used based on 99 different attributes.

Caffeine content varies by roast level, diminishing with increased roasting level: light roast, 1.37%; medium roast, 1.31%; and dark roast, 1.31%. However, this does not remain constant in coffee brewed from different grinds and brewing methods. Because the density of coffee changes as it is roasted, different roast levels will contain respectively different caffeine levels when measured by volume or mass, though the bean will still have the same caffeine.

Home roasting

Home roasting is the process of roasting small batches of green coffee beans for personal consumption. Even after the turn of the 20th century, it was more common for at-home coffee drinkers to roast their coffee in their residence than it was to buy pre-roasted coffee. Later, home roasting faded in popularity with the rise of the commercial coffee roasting companies. In recent years home roasting of coffee has seen a revival. In some cases there is an economic advantage, but primarily it is a means to achieve finer control over the quality and characteristics of the finished product.


Extending the shelf life of roasted coffee relies on maintaining an optimum environment to protect it from exposure to heat, oxygen, and light. Roasted coffee has an optimal typical shelf life of two weeks, and ground coffee about 15 minutes. Without some sort of preservation method, coffee becomes stale. The first large-scale preservation technique was vacuum packing in cans. However, because coffee emits CO2 after roasting, coffee to be vacuum-packed must be allowed to de-gas for several days before it is sealed. To allow more immediate packaging, pressurized canisters or foil-lined bags with pressure-relief valves can be used. Refrigeration and freezing retards the staling process. Roasted whole beans can be considered fresh for up to one month if kept cool. Once coffee is ground it is best used immediately.

Emissions and control

Particulate matter (PM), volatile organic compounds (VOC), organic acids, and combustion products are the principal emissions from coffee processing. Several operations are sources of PM emissions, including the cleaning and destoning equipment, roaster, cooler, and instant coffee drying equipment. The roaster is the main source of gaseous pollutants, including alcohols, aldehydes, organic acids, and nitrogen and sulfur compounds. Because roasters are typically natural gas-fired, carbon monoxide (CO) and carbon dioxide (CO2) emissions result from fuel combustion. Decaffeination and instant coffee extraction and drying operations may also be sources of small amounts of VOC. Emissions from the grinding and packaging operations typically are not vented to the atmosphere.

Particulate matter emissions from the roasting and cooling operations are typically ducted to cyclones before being emitted to the atmosphere. Gaseous emissions from roasting operations are typically ducted to a thermal oxidiser or thermal catalytic oxidiser following PM removal by a cyclone. Some facilities use the burners that heat the roaster as thermal oxidisers. However, separate thermal oxidisers are more efficient because the desired operating temperature is typically between 650–816 °C (1,202–1,501 °F), which is 93–260 °C (199–500 °F) more than the maximum temperature of most roasters. Some facilities use thermal catalytic oxidizers, which require lower operating temperatures to achieve control efficiencies that are equivalent to standard thermal oxidisers. Catalysts are also used to improve the control efficiency of systems in which the roaster exhaust is ducted to the burners that heat the roaster. Emissions from spray dryers are typically controlled by a cyclone followed by a wet scrubber.

Today, coffee is known as one of the most popular beverages, due to the fact that it has tonic properties, pleasant taste and aroma.Green coffee does not exist as a separate variety, but as a cake mix usual black coffee.Green coffee is not undergone heat treatment or roasting of natural coffee beans Arabica or Robusta varieties.Arabica contains less caffeine and fat compared to the Robusta variety.This is due to the lack of heat treatment in coffee stored maximum amount of vitamins, antioxidants and other nutrients.Consider how the green coffee preparation and its properties.

Preparation of green coffee

If you own roast coffee beans, you can get a better taste because of roasting depends on the duration of the aroma and taste of the drink.Cultivation of this “green” coffee should be on clean soil, fertilizer is not applied means to combat pests and synthetic fertilizers.So, for the preparation of green coffee to heat it in a skillet, stirring constantly, until brown.Duration frying average of 5-15 mi

nutes, depending on your taste.

Green coffee can be prepared in several ways.To make coffee, you will need to stock up on beans, coffee grinder, mortar or grinder, Turks or pan, strainer and the container in which you pour a drink.To prepare one serving of the drink into a glass with 100-150 ml of water needed to fill 10-15 grams of coffee beans.Do not grind the coffee to a powder, it is enough to do 3-4 short sessions grinding to obtain the necessary weight so that you can get a rich taste and a drink will be deprived of an unpleasant texture, which is supersaturated with fine particles.After preparation phase grains to the preparation should proceed to thermal processing.Turku or another container to pour 150 ml of water.Water should be poured taking into account the amount of evaporation of some of its short-lived when boiling.Water should be slightly warm, but do not bring it to a boil.The coffee mixture is poured into a Turk, and continues the process of heating.The fire must be maintained at an average level, should be periodically stir the mixture and ensure that the coffee does not boil over.Boiling coffee should be carried out with the lid open.When will the boiling water on the surface will appear a little foam, which means accession to the reaction of coffee beans with water and return it nutrients.After the beginning of the boiling process starts to give coffee its color, and you’ll notice staining water green.The duration of the boiling process should not exceed 3 minutes.To use it you need a coffee filter, which should take a clean strainer having small cells, and the capacity in which you pour a drink.It is necessary to carefully filter coffee.The drink has a green tint, and is different from the classic taste of coffee.The result is a piece of coffee 100-120 grams, sufficient to develop a drink all their useful properties in the body.Coffee can be consumed.It is advisable to take a drink 20-30 minutes before the first meal or before they begin to engage in sports that have a significant impact on the results than training and improve metabolism.

properties of green coffee

proved that green coffee promotes weight loss.In addition, regular use of green coffee may obstruct the body’s absorption of fat.Coffee beans contain tannins, caffeine, purine alkaloids.It is known that caffeine is used as a natural stimulant of physical and mental activity.Due to the caffeine, which includes coffee, successfully fighting with a headache and pain, wearing spasmodic.The limited amount of caffeine is useful to humans – it helps to improve the work of the higher nervous system, they enhanced the memory of man, stimulated lymph drainage, as well as strengthening the cardiovascular muscles.In addition, the properties of green coffee is the fact that the extract from it are used for the needs of aesthetic physicians and cosmetologists.Green coffee can be used if there is the need to strengthen the hair follicles, their recovery, nutrition, enhancing shine.Also, the green coffee is useful if your skin suffers from dryness, it needs moisture and protection as containing antioxidants the body cleared, and provide the necessary circulation of moisture.In addition, the green coffee beans have been used as a means to prevent formation of wrinkles, for treating skin lesions, such as scars, scars, stretch marks and cellulite.

While traditional black coffee is made from roasted coffee beans, green coffee beverages are made using the unroasted, or “green,” coffee beans. Extracts from green coffee beans have demonstrated many health benefits in scientific studies. The main components of green coffee responsible for these benefits appear to be caffeine and chlorogenic acid, a type of antioxidant, although some effects are influenced by factors other than these compounds.

Potential Weight Loss

According to a study published in March 2006 in “BMC Complementary and Alternative Medicine,” daily supplementation of an extract prepared from green coffee beans reduced body fat and body weight in mice, as well as fat composition in the liver. The effect was similar in mice supplemented with isolated chlorogenic acids and caffeine, which suggests that these are the compounds responsible for the effect. Chlorogenic acids found in green coffee can be digested and absorbed by humans, which implies a similar availability as the extract.

Reduction of High Blood Pressure

In addition to its effects on promoting weight loss, chlorogenic acids in green coffee can reduce blood pressure. According to a study published in 2006 in “Clinical and Experimental Hypertension,” patients supplemented with 140 milligrams of green coffee bean extract per day demonstrated reduced blood pressure throughout the study. No side effects were reported, which suggests that green coffee is a safe way to help reduce high blood pressure.

Improved Mood and Cognitive Performance

The caffeine found in green coffee has a positive effect on your mood and brain activity. According to a review published in February 2008 in “Nutrition Bulletin,” several studies have confirmed that caffeine can improve reaction time, vigilance, memory, alertness, focus, fatigue resistance and other factors of cognitive performance. Reviewers found the optimal intake of green coffee to be between 38 to 400 milligrams per day, or between approximately 1/3 cup to four cups of brewed coffee.

Benefits From Antioxidants

Green coffee beans and their derived products contain multiple antioxidants, which are compounds that reduce the effects of cell-damaging free radicals in the body. This preventative function keeps you healthier by reducing the amount of damage and stress your cells can take. According to a study published in July 2004 in the “Journal of Agricultural and Food Chemistry,” chlorogenic acid antioxidants in green coffee beans could prevent the proliferation of four kinds of cancer cells, suggesting green coffee may be useful in preventing some types of cancer.

What is green coffee bean extract?
You’ve probably heard about the long-standing health debate on drinking coffee. Researchers go back and forth on whether the popular brew is good for you. There is also controversy about the use of green coffee beans. They became well-known as a weight loss supplement after being featured on “The Dr. Oz Show.”

Green coffee bean extract comes from coffee beans that haven’t been roasted. Coffee beans contain compounds known as chlorogenic acids. Some believe these compounds have antioxidant effects, help lower blood pressure, and help you lose weight.

Roasting coffee reduces chlorogenic acid content. This is why drinking coffee isn’t thought to have the same weight loss effects as the unroasted beans.

The extract is sold as a pill and can be found online or in health food stores. A typical dose is between 60 to 185 milligrams per day.

Claim: Fact or fiction?

Does green coffee extract actually promote weight loss? There haven’t been a lot of studies on chlorogenic acids and their effectiveness as weight loss supplements. A review of human studies did show that green coffee extract may have the potential to help with weight loss. But the documented effects on weight loss were small, and the studies weren’t long term. The studies were also poorly designed. So, there isn’t enough evidence to say that the supplements are effective or safe. More research is needed.

Side effects

Negative side effects for green coffee extract are the same as regular coffee since the extract still contains caffeine. Common side effects of caffeine are:

  • upset stomach
  • increased heart rate
  • frequent urination
  • trouble sleeping
  • restlessness
  • anxiety

What should I look out for?

Since green coffee beans became popular, the Federal Trade Commission (FTC) sued at least one company for false marketing and making unrealistic claims about weight loss. Senators on Capitol Hill questioned Dr. Oz for promoting green coffee beans and other “miracle” weight loss products without adequate scientific support.

Both the FTC and the Food and Drug Administration (FDA) recommend doing research and using caution when it comes to supplements. Scientific research should back dietary supplement claims. And you should be skeptical of products that claim to help you drop weight fast without changing your habits.

The FTC is responsible for making sure companies don’t use misleading language to confuse and deceive consumers. And the FDA regulates ingredients and product labels. But dietary supplements don’t require FDA approval before they go on the market. Private companies are responsible for doing their own research and testing. The FDA may not get involved until reports of false claims or dangerous side effects surface.

Like many other supplements, green coffee bean may be marketed as a natural solution to weight loss. The term “natural” is common in the supplement industry, but it doesn’t necessarily mean a product is safe. In fact, there is no legal definition of “natural.” Many plants that grow in nature can be deadly, and natural supplements can still have added, unnatural ingredients.

If you’re thinking about trying green coffee beans as part of your weight loss plan, check the company you’re buying from on the FTC’s website. Make sure they aren’t being accused of fraud or contaminating their products with unlisted ingredients. It’s also important to discuss any supplements with your doctor, especially if you have other conditions like high blood pressure or diabetes, or are taking medications.

What else can I do to lose weight?

Long-term weight loss is about adopting a healthy lifestyle and sticking to it. Green coffee bean extract may help, but many experts agree that there is no substitute for maintaining a healthy diet and getting regular exercise. The Centers for Disease Control and Prevention (CDC) recommends cutting your daily calorie intake by 500 to 1000 calories and getting 60 to 90 minutes of moderate physical activity most days of the week.

It is curious that has products that nature puts us within reach of the hand for centuries, these are used in traditional medicine during the same period, but for those who give to know or come to light is not easy, until a celebrity makes it fashionable or is associated with benefits both the people pursues today , as it is the fact of having a body 10 or lose weight.

The history of green coffee fits perfectly with the description you just give. And it is that you it’s a type of product that exists, as if to say, since man is man; that for centuries has been used in traditional medicine to improve health or combating certain problems related to the same, but, really, not given to know too much until its properties have not partnered with the fact that it helps to lose weight and it had everything to do the propaganda that made it famous as Demi Moore , Jennifer López or Katy Perry, among others.

People who are equipped with sufficient weight and influence to talk about the virtues or defects of a product, in this case, a type of coffee, as it is the Green and that today we want to focus, it’s true: green coffee helps to lose weight, but also characterized by other comprehensive listing of benefits which we would like to speak today in this post.

What is the green coffee?

This is the first question you would like to respond, since the origin of any product is the best basis to explain what are its Properties and benefits.

Unlike what many it may seem them, green coffee has not gone through any kind of processing, but quite the opposite. And it is that green coffee is not something else, but the natural grain of the coffee, without having gone through the process of torrado or roasted plant, that is the usual step through which pass the coffees that come to the catering establishments or to our home.

The green coffee bean has not finished its maturation process and its natural color is green, so this type of grain is named for its color.

Main differences between green coffee and roasted coffee

Once people know what to the green color of the coffee bean, the most common question tends to be the differences with which we usually take, the roasted coffee. In this regard, it is worth mentioning the following:

  • Processing: as we have already said, green coffee has not gone through any kind of process and the black coffee if: has been toasted or torrado.

  • Aroma: black coffee has, depending on the variety, a scent or another that characterizes him. More or less intense, but always has an aroma that dominates insofar as we have grains of black coffee to our around. However, with green coffee would not happen, since the aroma is very slight.

  • Flavor: the green coffee is much more bitter, recalling sometimes to those more pajoso flavor infusions; opposite to the roasted coffee, having a body and a strong flavor that will change according to its origin and variety.

  • Degree of caffeine: is higher in the case of the roasted coffee. Green coffee contains caffeine, but in smaller amounts.
