Roasting
Coffee roasting is the process of heat-treating coffee beans, during which the raw coffee beans develop delicious aromas and distinctive flavor notes. During the roasting process, the color, taste, and aroma of the coffee beans fundamentally change. The coffee beans are exposed to high temperatures and various durations in a roasting machine.
Different roasting levels create different flavor notes:
Light roast: Characterized by a short roasting time and low temperature. The result is a light body, high acidity, and a fruity, floral flavor profile.
Medium roast: The coffee beans are given additional time and heat. It creates a balance between body and acidity, with distinctive chocolate and nutty flavor notes.
Dark roast: Characterized by a longer roasting time and high temperature. The result is a deeper body, lower acidity, and strong roasted, cocoa flavor notes.
Coffee roasting depends on personal preferences, and coffee enthusiasts experiment with different roasting levels to find the coffee that best suits their taste. The roasting levels determine the flavor and character of the coffee, making the roasting process crucial in shaping the quality and enjoyment of the coffee.


Flavor and Aroma Notes
The aroma and flavor notes of coffee open up a world of complex and rich experiences for coffee lovers. Numerous factors play a role in the development of these notes, ranging from the type and terroir of the coffee beans to the degree of roasting and the method of preparation.
Characteristic Aroma Notes:
Floral: Fresh and floral aromas, such as jasmine or lily, that can be detected in coffee, providing a special and light sensation.
Fruity: The aroma of coffee can often contain fruity notes, such as citrus fruits, berries, or ripe cherries, which refresh the senses.
Chocolatey: Cocoa or chocolate aromas developed during roasting give coffee a rich and warm feeling, sometimes complemented by vanilla or caramel.
Spicy: Various spice aromas, such as cinnamon, cloves, or ginger, emanating from the coffee, offer a unique and warm experience.
Flavor Notes:
Fruity: Various fruit flavor notes, such as apple, blueberry, or tropical fruits, that enrich the coffee's flavor profile.
Sugary: Sweet flavor notes, such as caramel, vanilla, or honey, that add sweet and pleasant notes to the coffee.
Roasted: Flavor notes developed during roasting, such as roasted, bitter, or chocolatey notes, that define the character and body of the coffee.
Spicy: Various spicy flavor notes, such as cinnamon, cloves, or nutmeg, that offer a spicy and intense experience.
These notes together create the complex flavor profile of coffee that coffee lovers can enjoy and explore. Unique coffee varieties and coffee terroirs bring additional diversity, so each coffee can have its own distinctive flavor and aroma world. Coffee drinkers often enjoy this rich palette and experiment with different coffee varieties to discover the most beloved flavor combinations for themselves.


Acidity
The acidity of coffee is an important element of its flavor profile and originates from two main sources: the coffee variety and the roasting process. The Arabica coffee variety generally has higher natural acidity, while Robusta tends to have lower acidity.
During roasting, the flavor notes of coffee beans transform, including the acids. Lighter roasted coffees often retain their higher natural acidity, resulting in a sharp and refreshing effect. Meanwhile, in darker roasted coffees, the roasting contributes to a reduction in acidity, while developing intense, roasted flavor notes.
Finding the optimal balance during roasting is crucial. The roast master must consider the characteristics of the coffee variety, the desired flavor profile, and consumer preferences. A well-roasted coffee will be balanced, with vibrant acidity, rich aromas, and a harmonious flavor profile. Thus, the roasting process not only shapes the body of the coffee but also defines the enjoyment experience of the coffee.


Methods of Coffee Preparation
The rich world of coffee preparation methods extends from traditional espresso to innovative pour-over techniques. Each method creates unique flavor profiles and requires different types of coffee.
1. Espresso:
Espresso is a short and intense coffee made by forcing hot water under high pressure through finely ground coffee. Ideally, it is made from arabica or blend coffee beans, with a strong roast level and fine grind.
Drip Coffee:
In drip coffee brewing, hot water is dripped over medium-ground coffee beans. This results in a lighter, balanced-flavored coffee. It is usually made from arabica coffee varieties with medium roast level and medium grind.
3. French Press:
In a French Press, medium-coarse ground coffee meets hot water, and after a longer steeping, the coffee brew is pressed into the serving pot. A full-bodied, aromatic drink is created, requiring medium-roasted arabica or blend coffee beans and medium-coarse grind.
4. Moka Pot Coffee:
Moka pot coffee is a traditional and simple coffee brewing method. In the moka pot, water passes through the grounds after boiling and extracts them. It is important not to continue heating the coffee maker after the first coffee drops appear, so neither the coffee grounds nor the finished coffee are exposed to more heat than necessary.
For moka pot coffee, medium-coarse ground arabica coffee beans are typically used, roasted to a medium-dark level, but the variety and blend are determined by personal taste.
5. Pour-Over:
In pour-over coffee brewing, hot water slowly pours over finely ground coffee. This is a manual and creative process where the coffee type (usually specialty coffee), roast level, and grind all affect the flavor.
6. Turkish Coffee:
Turkish coffee uses finely ground Turkish coffee beans, brewed with sugar and water in a special Turkish coffee pot. The result is a dense and intense drink, where the fine roasting and very fine grinding of the coffee beans are crucial.
7. Cold Brew
Making Cold Brew coffee is extremely simple. It requires medium or dark roasted coffee, coarsely ground. Mix 100g of coffee with 400g of cold water and place it in the refrigerator for at least 12-24 hours. Thanks to the long steeping, you get a smooth, slightly sweet, and low-acidity drink. Strain it, then garnish if desired. You can experiment with the ratios and steeping time to achieve a personalized flavor profile. Medium or dark roasted coffee provides the rich and distinctive notes for Cold Brew coffee.
Each coffee preparation method creates its own unique flavor and aroma world, and the quality of the coffee type, roast level, and grind is crucial to achieving the desired taste experience. Through experimentation and developing personal taste, every coffee lover can discover the perfect preparation method and coffee for themselves.
