The Science of Coffee: What Makes a Great Brew?
7th Jun 2025
The Origin of Flavor
The flavor of coffee begins at its origin, with factors like soil composition, altitude, and climate playing vital roles.
- Soil: Coffee plants thrive in rich, volcanic soil that is high in nutrients. This type of soil influences the overall health of the coffee plant and contributes unique flavor notes to the beans.
- Altitude: Higher elevations often yield coffee with a complex flavor profile. The cooler temperatures slow the growth of coffee cherries, allowing them to develop a richer taste. Many of the exotic locations we source from, like the mountainous regions of Colombia and Ethiopia, provide these ideal growing conditions.
- Climate: Coffee requires a specific climate with plenty of rainfall and sunlight. The balance of these elements can create magnificent flavor variations that reflect the coffee’s home region.
The Processing Method
Once harvested, coffee beans undergo various processing methods, each influencing the final taste of the brew. The primary methods are:
- Washed (or Wet Process): This method involves removing the coffee cherry’s outer fruit before fermentation. Washed coffees are typically brighter and have cleaner flavors, allowing the characteristics of the bean to shine.
- Natural (or Dry Process): This method allows the bean to dry inside the cherry, imparting fruitier notes. Natural-processed coffees often have a heavier body and more complex flavor profiles.
- Honey Process: This hybrid method retains some of the mucilage while drying, offering sweetness and fruitiness without the overpowering characteristics of full natural processing.
At our coffee shop, we emphasize the beauty and complexity of these different processing methods, often showcasing beans from various regions to highlight their unique flavors.
The Roast
Roasting is where the magic truly happens. The degree to which coffee is roasted can bring out different flavors within the bean:
- Light Roast: Known for its bright, acidic notes, a light roast retains much of the bean’s original flavor profile, allowing for floral and fruity tasting notes.
- Medium Roast: This roast strikes a balance, offering a rounded flavor with hints of sweetness and a moderate acidity.
- Dark Roast: This roast is often characterized by its bold, rich flavor, with deep chocolate and smoky notes but can mask the original attributes of the bean.
Each roast unlocks a different side of the coffee, and at our shop, we take pride in offering a range of roasts that cater to diverse preferences while maintaining the integrity of the coffee's origins.
Brewing Methods
How you brew your coffee can also significantly impact its flavor. Various brewing methods — from French press to pour-over to espresso — extract different elements from the coffee.
- French Press: This method allows oils and compounds to remain in your cup, providing a rich and full-bodied taste.
- Pour-over: Pour-over methods provide clarity and cleanliness, emphasizing the unique flavor notes of the specific bean.
- Espresso: This concentrated coffee is bold and robust, perfect for a quick caffeine kick, often used as the base for other coffee drinks.
The Importance of Freshness
One of the most crucial aspects of brewing great coffee is using fresh beans. Ideally, coffee should be consumed within two to four weeks of roasting. We recommend purchasing whole beans and grinding them just before brewing to ensure maximum freshness and flavor.
