How does coffee get its flavour ?

1. The Coffee Plant 🌱

Just like apples or grapes, coffee comes in different varieties, and each variety has its own unique characteristics. Two of the most popular coffee plant varieties are Bourbon and Typica. These varieties have distinct flavour profiles influenced by their genetics. For example, Bourbon often offers sweet, fruity notes with a silky body, while Typica might give a more balanced cup with notes of chocolate and nuttiness. Much like different apple varieties (like Granny Smith or Fuji), each coffee plant brings its own flavour nuances to the cup.

2. Where It Grows 🏔️☀️

The environment where coffee grows is key to its flavour. Coffee thrives in tropical climates at high altitudes—usually between 1,000 to 2,000 meters above sea level. The cooler temperatures at higher altitudes slow the growth of the coffee cherries, leading to a denser, more flavourful bean. The soil and climate also play a big role in the taste. For instance, Rwandan coffee grows in volcanic soil at high elevations, which results in a bright, fruity profile with rich sweetness. Similarly, coffees grown near the equator, where temperatures are more consistent, can develop more balanced flavours. Other factors, like rainfall and sunlight, influence how quickly the cherries ripen, affecting the flavour development.

3. How It’s Processed 🚿☀️

Once the coffee cherries are harvested, the processing method can drastically change the flavour of the final cup. There are a few different ways coffee is processed after it’s picked:

- Washed Process (Wet Process): The coffee cherry’s skin and fruit are removed before the beans are dried. This process results in a clean, bright cup with clear, fruity notes, as it removes the fruity pulp from around the bean.

- Natural Process (Dry Process): The whole cherry is left to dry in the sun before being hulled. This process imparts a fruitier, more intense sweetness to the coffee, often with wine-like or berry-like notes because the beans absorb some of the natural sugars from the fruit during drying.

- Honey Process: A hybrid of the washed and natural methods, the coffee cherry’s skin is removed, but some of the sticky fruit pulp is left on the bean while it dries. This process tends to give the coffee a sweeter, fuller body with mild fruity undertones, balancing brightness and sweetness.

4. Roasting 🔥

Roasting transforms green coffee beans into the aromatic, flavourful beans we brew. The process is much like toasting bread—heat is applied to bring out different flavours. The degree of roasting plays a huge role in the final taste:

- Light Roasts: These are roasted for a shorter time, preserving the bean’s natural flavours. Expect brighter acidity and fruitiness, as the unique flavours of the coffee plant and its origin are most prominent at lighter roast levels.

- Medium Roasts: These beans have a balanced flavour, where the natural notes of the coffee and the effects of roasting (like caramelization) combine. You’ll notice both fruity and sweet characteristics with a fuller body.

- Dark Roasts: These are roasted for a longer time, which results in a bold, rich flavour profile. The coffee takes on roasted, chocolatey, or even smoky notes, often masking the more delicate flavours that come from the coffee plant’s origin.

5. Brewing ☕

The method you use to brew coffee has a big impact on how the flavours are extracted from the beans. Different brewing methods bring out different characteristics in the coffee:

- Espresso: Brewing under high pressure extracts a concentrated, full-bodied shot with intense flavours. Espresso often emphasizes the richness and depth of coffee, bringing out chocolatey or caramel notes.

- Cafetière (French Press): This method uses immersion, allowing the grounds to steep in hot water for several minutes. It produces a fuller-bodied cup with a smooth texture, ideal for showcasing the coffee’s richness and heavier flavours.

- Pour-Over (V60, Chemex, etc.): This drip brewing method allows for more precise control over extraction, resulting in a clean, vibrant cup. Pour-over methods are great for highlighting fruity, floral, and bright flavours, as they allow for slow, even extraction.

- Aeropress: Known for its versatility, the Aeropress allows for quick brewing with both pressure and immersion. It often produces a coffee with a rich, smooth body and bright flavours, similar to espresso but with more clarity.

Just like how different cooking methods bring out unique aspects of ingredients, each brewing method enhances certain flavour notes in coffee. The way you brew is like the final touch on a dish, ensuring the coffee’s full potential is realized in the cup.

SIMPLY VERSION :

1. The Coffee Plant 🌱

• Different coffee varieties (like Bourbon or Typica) have unique flavours, just like different apple types taste different.

2. Where It Grows 🏔️☀️

• The soil, altitude, and weather affect the taste. For example, Rwandan coffee is often fruity and sweet because of the high mountains and rich soil.

3. How It’s Processed 🚿☀️

• After harvesting, coffee cherries are processed in different ways (washed, natural, honey-processed). This changes the flavour—washed coffees are clean and bright, while natural ones are fruity and sweet.

4. Roasting 🔥

• Roasting coffee is like toasting bread. Light roasts are more acidic and fruity, while dark roasts taste bold and chocolatey.

5. Brewing ☕

• The way you make coffee (espresso, cafetière, pour-over) changes how it tastes. Think of it like cooking—boiling, frying, or baking the same ingredient gives different results.
