Did you know that…
… green coffee is not a special kind of coffee? All coffee beans are green when raw and unroasted. After the drying process and separation from the pulp, they are ready for further processing. To preserve their freshness, they are further distributed. Subsequently, they go through the roasting process into the form we know – aromatic dark brown grains.
However, unroasted coffee fruits have an undeniable advantage over the final product, which has gained them a lot of fans lately. They contain caffeine, lipids, amino acids, potassium, carbohydrates and antioxidants. These substances beneficial to the human body are lost during roasting. The research confirmed that when processing raw coffee beans at a temperature of 230 to 250 degrees Celsius for 12 to 21 minutes, the total antioxidant content was halved. Just one particular antioxidant, chlorogenic acid, has elevated green coffee to a healthy weight loss remedy.
Chlorogenic acid primarily slows down the aging process of cells. It further lowers blood pressure and blood sugar levels due to the absorption of carbohydrates from the digestive tract. The study confirmed an association between chlorogenic acid and weight reduction. This acid has been shown to improve the function of the hormone adiponectin, which increases the oxidation of fatty acids and prevents the storage of fats in the body. By drinking this unusual beverage regularly, you can prevent the development of diabetes, reduce the risk of cardiovascular disease or cancer and last but not least, lose some extra pounds.
We must also not forget the caffeine content, which is the same in green coffee as in roasted coffee. Caffeine has stimulating effects on the central nervous system, which in most cases is associated with a reduction in fatigue. However, this stimulation also increases the rate of metabolism. Caffeine increases the so-called Rest Metabolic Rate by 3 to 11%. Peaceful metabolism is an indicator of how easily our body burns calories at rest. The higher the value, the higher the energy consumption and the more one can indulge in eating without fear of extra pounds. Therefore, with regular (but not exaggerated) drinking coffee, there is a greater chance of weight loss. Beware, however, with long-term consumption of any beverages containing caffeine, there is a risk that the body will develop resistance to its effects.
During the whole period we have been working with green coffee, we have become one of the largest sellers. Thanks to this, we had the opportunity to collect information directly from our customers. We have met with various reactions, but especially the positive ones.
The most common reactions were:
- faster digestion
- weight loss
- pressure adjustment
- energy boost
- special taste
There were also people who prefer classic roasted coffee. In the end, everyone has different taste. And what do you like? Do you belong to the club of lovers of this healthy delicacy, or do you lean towards the good old classic roasted coffee?
Caffeine is a substance that is found freely in nature in various plants, their leaves, flowers or fruits. When caffeine is mentioned, everyone is probably thinking of coffee immediately. And here comes the everlasting dilemma. Is caffeine dangerous, or is it just a myth?
Many studies show that caffeine has health benefits. It has a positive effect on the human body inside and out. The effects of caffeine have been known since ancient times. Its ability to affect the human body is amazing and is therefore used in many areas such as gastronomy, cosmetics, the pharmaceutical industry, etc.
But most often everyone sees caffeine in connection with coffee. This second best-selling commodity in the world is a rich source of antioxidants for the human body. The stimulating effects of coffee on the human body are well known and therefore many cannot imagine their morning routine without it. However, everything needs to be done in moderation. Excessive caffeine consumption can also cause side effects such as anxiety, sleep disturbances, palpitations and restlessness.
According to the American National Coffee Association (NCA), a regular cup of (dripped) coffee contains approximately 65-120 mg of caffeine. However, the amount of caffeine in the cup cannot be generalized, it is influenced by several factors that we must take into account when preparing coffee:
- Coffee bean type – Arabica coffee beans are known to contain less caffeine than robusta beans.
- Roasting – lighter roasted coffee has a higher caffeine content than darker roasted coffee.
- Type of coffee – the caffeine content can vary significantly between filtered coffee, espresso, instant coffee and decaffeinated coffee. Filtered coffee usually contains more caffeine than espresso.
- Serving size – “one cup of coffee” can range from 15 to 300 ml, which also affects the total caffeine content.
- Brewing time – the longer the water flows through the ground coffee, the more caffeine is released
- Although the name can be misleading, decaffeinated coffee is not completely decaffeinated, on average it contains about 3mg of caffeine.
The daily dose of caffeine should not exceed 200-300 mg, which corresponds to approximately 5-6 properly prepared espressos from the Arabica variety.
Caffeine has also found great use in the cosmetics industry. How to keep your skin tout as long as possible? How to slow down aging?
Cosmetic companies have begun to add coffee and coffee berry extracts – caffeine – to many of their products. Studies whose results have been published in the Journal of Investigative Dermatology, show that caffeine breaks down UV-infected cells without damaging healthy cells. Due to its anti-inflammatory and stimulating properties, it has a positive effect on the skin and penetrates through it into the body.
Coffee peeling is currently experiencing a big boom. This cosmetic product is a mixture of roasted and green coffee in combination with various oils. And the effects?
- helps remove dead skin
- has an anti-inflammatory effect
- thanks to the caffeine content, which strengthens the skin, it can help reduce cellulite
- antioxidants prevent the formation of wrinkles and prevent premature skin aging
- relieves eye swelling, can help reduce circles under the eyes
- contributes to the overall regeneration of the skin
To sum it up, there is a difference between taking caffeine through coffee and the difference between applying a caffeine-containing cosmetic product to the body. While the caffeine contained in coffee gets directly into the body, which we apply through the cream, brings benefits only locally.
Every human body is different and reacts individually, so only yourself can find out, how beneficial is caffeine for your body
The trend of enjoying quality coffee in the comfort of home has put coffee lovers in front of a difficult decision. How to choose the variety, the degree of roasting or the thickness of grinding? With growing concern about the environment and overall quality of life, another question is crawling into our minds: regular or organic coffee?
Coffee is the second most traded commodity in the world after oil. In 2014, the world consumption was estimated at 149.3 million bags of coffee, which is almost nine billion kilograms of coffee. To meet mass demand, production was maximized to such an extent that coffee cultivation began to harm the environment. Therefore, the question of choosing between regular and organic coffee is very relevant in the current situation.
Many synthetic fertilizers, pesticides, herbicides, fungicides and insecticides are used in the cultivation of coffee, as well as in the cultivation of other crops. Growers and coffee collectors are thus exposed to these harmful substances, which can cause various health complications and serious diseases. These chemicals continue to enter the water and air. Thus, another vulnerable group is people living near coffee plantations, who are directly threatened by the surrounding chemicals.
The plantations themselves are also a problem. They were mostly preceded by deforestation, so that hybrid varieties of coffee could ripen in direct sunlight. There is a risk of landslides during heavy rains in the tropics. Erosion is usually caused by the grubbing-up of the forest stand, the root system of which ensured the stability of the soil. In addition, during rains, chemicals are washed out of the soil and there is a risk of contamination of drinking water sources, animal death and human health complications.
What makes organic coffee growing better for the environment? The product is only labeled as organic when grown on soil that has not been chemically treated for at least three years. This time period is required for the soil to be cleaned of all chemicals. Organic farming uses natural fertilizers – coffee husks, chicken manure or compost. These types of fertilizers do not have a negative impact on the environment, whether it is the quality of the soil, water, air or the lives of its inhabitants.
Most of the production of organic coffee is grown in the shade of the forest. There is no need to artificially create plantations when the forest provides everything needed for growing coffee. Coffee trees naturally prefer shade. Birds and reptiles, which lose their natural habitat during deforestation, are very useful in growing coffee. These animals feed on insects parasitizing on coffee trees. Conventional coffee cultivation uses unnecessarily large amounts of pesticides and insecticides, as the absence of birds and reptiles causes pests to multiply in the area.
Growing organic coffee is beneficial for both the ecosystem and the end consumer. This is not a new trend, as all products have been organically grown in the past. Thus we can say, organic production is successfully verified over the time.
Arabic wine. That’s what Europeans used to call coffee in the past. Today, many know it only as dark, chocolate-brown grains stored in various containers.

Just as grapes used for wine have many varieties, so does the coffee trees. They grow in about 70 countries around the world with suitable climatic conditions. These areas are referred to as the “coffee belt” and are found between the Tropic of Cancer and the Tropic of Capricorn.
The whole process of coffee beans treatment is fascinating. Before coffee can land in a cup, it has to go a long way, which starts with a coffee tree. The farmer on his plantation takes care of that. Thanks to his many years of experience, he knows when is the best time to collect. Coffee cherries are harvested in a more complex (manual) way, or in a less expensive way, also called unsorted harvesting.
The green beans that the farmer obtains from coffee cherries, which we, the roasters, are interested in, are processed by the three most common methods, which have a significant effect on the overall taste of coffee. The farmer decides whether he wants to process the grains by the wet, dry or honey method. The wet method gives the coffee chocolate and nut tones. Dry (natural, dry) processing will highlight especially fruity and more acidic tastes, and finally the honey method emphasizes sweeter tones and thanks to it, coffee also acquires a consistent body. In addition to these known methods, there are many variants with small differences in the processing. However, they are very easy to recognize in taste. Such methods belong to a common group called experimental.
Roasters then turn the green beans into tasty, roasted beans suitable for making coffee. We offer mainly coffee beans called Coffea Arabica.
If you’ve ever walked through Obchodná street in Bratislava, you may have smelled a delicate, caramel scent that easily overwhelms the senses. Most likely we just roasted one of our coffees. Roasting is the alpha and omega of its final taste. It is due to different roasting that its assorted tastes are created. We are a local roastery that focuses mainly on roasting with the designation City + and Full City, which means darker roasting used mainly for espresso. Over time, however, we have expanded our offer to include light-roasted species, which are principally suitable for preparation using alternative methods, such as V60, Chemex, Vacuum Pot, Nitro Brew, Cold Brew, frenchpress or mocha.

Roasting coffee is an art and a science at the same time. It is a complex process in which coffee beans change from green to pale or dark brown. Roasting is what influences the taste of coffee the most.
Green grains have no properties of roasted grains. They are hard, tasteless and have a grassy scent. Roasting turns them brown, crunchy with a typical aroma and taste, as we see them most often – ready to grind and make coffee.
During roasting, chemical and physical changes take place inside the grains, thanks to which they gradually transform. Most of the moisture evaporates from the grains, they increase their volume, their density decreases and thus they lose weight. Coffee beans lose 12-25% of their weight during roasting. The sugars present in the green grains caramelize under the influence of heat, which, in addition to the high temperature, also contributes to the colour change. When roasting, two types of “cracking” can be heard: first as the water escapes of the grains, when caramelization begins. In the second cracking – carbon dioxide gets out. The cracking is very loud, it can be compared to the popping of popcorn. The green grains gradually pass through the yellow, pale brown to dark brown colour, depending on the degree of roasting. As the coffee is roasted to a darker colour, oils are being formed in the beans and come to the surface.
Once the optimum properties have been reached, the coffee must be drained from the roaster and cooled immediately, otherwise the roasting process would continue, which could reduce the quality of the coffee and change its final taste.
Light roast is suitable for alternative preparations, it emphasizes the natural fruity character of the coffee, acidity, floral tones and aroma.
In medium roast, the characteristics supported by roasting are being amplified, the natural properties of the coffee begin to be lost and a balance between acidity and the body of the coffee is created.
The darker the roast, the more the acidity disappears and the easier is to feel the specific roasting profile rather than the characteristic tones of the individual coffee.
Many people wrongly believe that the darker the roasted coffee, the stronger it is in terms of caffeine content. However, the longer the grains are roasted, the lower is the caffeine content. We roast our coffees light (especially suitable for making filtered coffee) or dark (for making espresso).
Many coffee enthusiasts get used to roast coffee at home. There are several ways to do this, for example on a special perforated pan, in a popcorn maker, or on a classic pan. These methods are cheap, but often at the expense of coffee quality. It is difficult to achieve equal roasting of all grains and the problem is mainly with their cooling. In case you would still decide to try roasting at home, we offer excellent green coffee beans of assorted varieties.
