COFFEE FLAVOR PROFILES: Coffee’s basic flavors (flavor profile)
Bitter Flavor (
The bitter flavor is one that everyone can detect right away when they consume this drink for the first time. Coffee beans, according to scientists, have a higher concentration of antioxidants than green tea. There are around 82 varieties of CGA acids in green coffee beans, and when the CGA acid breakdown events begin, the coffee will have a bitter taste. Chlorogenic acids are the most common. The bitter taste in coffee is caused by the chlorogenic acid isomer 5-caffeoylquinic acid and di-CGA, which are found in green coffee.
Sour Flavor (taste)
This acidic flavor is less noticeable in green coffee beans. The acidity of the coffee is altered throughout the roasting process, resulting in various and more prominent acidity levels. Lightly roasted coffee has a more acidic flavor than dark roast coffee.
Sweet Flavor (roast, recipes)
Many of us drink coffee that has been sweetened with milk or sugar because we can’t bear the bitterness of the original coffee; as a result, we don’t realize that the actual coffee has sweetness. However, while there is sweetness in coffee, the offensive is so strong that we find it difficult to detect it. Because coffee has a sweet flavor due to the amount of fructose and glucose in the beans, we won’t be able to see the sweetness right away at the tip of our tongue. Instead, after drinking, a mild sweetness stays in the throat, making coffee taste delicious. The sweet flavor will neutralize the bitterness and sourness of the coffee.
It may sound strange to you, but real coffee beans have a salty taste. The salty flavor derives from the mineral salts found in coffee beans, which are generally in the form of free inorganic salts like NaCl and KCl. We can immediately detect the salty flavor when drinking cold coffee. A salty flavor in coffee is sometimes undesired since it can mask the bitterness and leave a harsh taste in the throat after drinking. However, the salty flavor will only be noticeable if the quality of the coffee you use is poor due to an incomplete extraction or preservation process.
COFFEE FLAVOR PROFILES: Factors that influence coffee flavors
After roasting, more than 800 taste components in coffee have been identified, ranging from green to roasted bean. Each coffee bean is made up of hundreds of different chemical compounds and is the result of natural flow and the farmer’s hand. The primary flavor of a coffee plant is determined by its origin. However, the other components, such as the soil and the type of water supply, contribute to the flavor, resulting in uniqueness and variability for each coffee bean collected. Furthermore, following harvesting, preliminary processing in various ways aids in transforming and enhancing the coffee’s flavor, giving us a wide range of options for our coffee beans. We’ll break down the flavor variances by variety, growing region, and preparation method.
Coffee Arabica is a type of coffee with slightly long beans. The taste of Arabica is slightly sour, mixed with mild bitterness and light brown watercolor. Phenolic compounds create the bitter taste of coffee, accounting for 8% of the volume of Arabica green coffee.
Robusta coffee has from 2 to 4 percent caffeine. Because the beans are more petite than Arabica, which is dried without fermentation, the flavor of Robusta coffee is consistently evaluated as inferior to Arabica, with a bolder, more bitter, and harsh taste and more acidity.
Coffee beans with a round form, robust aroma, and bitter taste are called Peaberry or Culi Coffee. Culi coffee beans, in particular, have a far greater caffeine content than Robusta and Arabica coffee beans. Coffee Culi is a relatively uncommon mutant, only accounting for 2-4 percent of the crop.
The Moka beans are small, firm, and irregularly shaped, with a hue that ranges from greenish-yellow to pale yellow. It has a moderately sour flavor and a unique flavor when consumed. This Moka coffee type is the most difficult to grow in the coffee family, needing meticulous attention.
Soil and climate
Climate and soil conditions fluctuate at different altitudes, affecting the source of nutrients absorbed by the plant and resulting in distinct coffee flavor profiles.
- At 600 meters, coffee usually has a solid harsh taste and a primary flavor.
- 600-760m: Coffee has a mild, earthy flavor at this elevation.
- 760-910m At this point, coffee takes on a pleasant, mellow taste.
- 910-1200m: Coffee contains citrus, chocolate, and vanilla flavors at this elevation.
- 1200-1600m: Coffee has a rich flavor, with notes of fruit and flowers.
There are currently three continents where coffee is grown: Africa, Asia, and Europe.
Coffee is grown mainly in Central and East Africa. Countries such as Kenya, Burundi, Malawi, Rwanda, Tanzania, and Zambia all have export markets for coffee beans. Coffee on this continent has a bright, balanced, sweet taste similar to that of tropical fruit.
Central and South American coffee regions include Brazil, Cuba, Colombia, Costa Rica, Jamaica, Ecuador, El Salvador, Paraguay, Guatemala, Honduras, Mexico, Nicaragua, Panama, and Hawaii. Floral, orange, lemon, and spice notes, with a light body, are typical of the coffee served here.
India, Yemen, Indonesia, Thailand, and Vietnam are some of the East and Southwest Asian countries. Asiatic coffee has a distinctive earthy aroma and sweet taste, and the chocolate flavor is slightly bitter and has a robust body.
There are currently three standard preliminary processing methods: wet, dry, and honey.
Dry – Natural Process
This production’s dry processing (also called the natural method) results in a sweet, mellow, yet nuanced flavor. This method is commonly employed in places where rainfall is rare and lengthy periods of sunshine allow the coffee to dry naturally. The dry processing method is used in the majority of coffees from Indonesia, Ethiopia, Brazil, and Yemen. However, because it is so reliant on the weather, this strategy is fraught with danger. Heavy rain will over ferment the coffee, resulting in dark and rotten beans.
Wet-processed coffee is a time-consuming technique that requires the removal of four layers surrounding the beans. The coffee beans become cleaner, brighter, sweeter, and more acidic as a result of this process (specific sour taste and natural fruity aroma). Wet processing is used by the majority of countries that produce high-quality coffee.
PULPED NATURAL PROCESS HONEY
This type of cooking is comparable to wet processing. On the other hand, people will not remove or retain all of the slimes before it dries. It is what gives the coffee bean a dark brown tint that resembles honey, as the honey processing method is named. When coffee is treated in this way, it retains a lot of sweetness and enhances the flavor.
