The soil’s mineral content and pH levels can impact the coffee’s taste and acidity.
For example, volcanic soils like those found in regions such as Costa Rica and Guatemala can impart distinct flavors and a higher acidity to the coffee beans.
Processing Methods and Their Impact on Coffee Varietals
The processing methods used after the coffee cherries are harvested significantly impact the flavor and characteristics of the final coffee beans.
There are several standard processing methods, each with its own unique effects on the taste profile of the coffee varietal.
1. Washed/ Wet Process: In this method, the outer skin of the coffee cherry is removed, and the remaining pulp is fermented and washed away.
This results in a clean and bright cup of coffee with higher acidity and floral or fruit flavors.
The washed process is commonly used for arabica coffee, enhancing its delicate and nuanced characteristics.
2. Natural/ Dry Process: In this method, the coffee cherries are dried with the fruit pulp intact.
As the cherries dry, they impart their sugars and flavors to the beans, resulting in a sweeter and fruity cup of coffee.
The natural process is commonly used in regions with limited access to water and is known for producing full-bodied and complex coffees.
3. Honey/ Pulped Natural Process: In this method, the skin of the coffee cherry is removed, leaving some or all of the fruit pulp on the beans.
The beans are then dried, allowing the sugars from the pulp to ferment and penetrate the beans.
The honey process produces a coffee with medium acidity, a smooth body, and a balanced sweetness.
4. Semi-Washed/ Semi-Dry Process: This method combines aspects of both the washed and natural processes.
The outer skin and some fruit pulp are removed, and the coffee beans are dried.
The semi-washed process can result in a coffee with a balanced acidity, fruity flavors, and a clean finish.
5. Experimental/ Alternative Processes: Coffee producers constantly experiment with different processing methods to create unique flavor profiles.
These methods include carbonic maceration, anaerobic fermentation, and enzyme soaking.
These processes can result in wildly different flavor profiles, often showcasing fruity, funky, or wine-like characteristics.
