Understanding the 7 Factors Influencing Your Brew

The factors influencing the flavour of coffee are diverse and complex, forming a series of elements that come together to create a unique coffee experience. At Terminal 3 Roasters, we believe that exploring these factors is key to understanding and enjoying the diversity of coffee flavours. In this Gateway article, we will explore the seven primary factors that significantly influence the flavour profile of your coffee.

Coffee Bean Varieties

One of the fundamental aspects of creating coffee flavour is the type of coffee bean used. Arabica and Robusta, the two most common coffee varieties, impart very different flavour characteristics. Arabica, with its softness and complexity, stands apart from the stronger and more robust Robusta. 

Geographical Origin

Every region where coffee beans are grown contributes unique nuances to the final flavour profile. Climate, soil, altitude, and unique geographical conditions shape the flavour characteristics that distinguish coffee from one region to another. 

Coffee Processing Methods

The coffee bean processing method, such as washed or natural processing, adds new dimensions to the coffee flavour. Each method brings out unique characteristics, altering the complexity and acidity of the coffee flavour. 

Roasting Level

Roasting coffee beans is not just a process but an art in guiding beans towards their desired flavour identity. The duration and temperature of roasting play a significant role in creating a balance between strength and smoothness. The right combination of roasting level and coffee variety produces a cup that expresses its unique character.

Freshness of Coffee Beans

Allowing time for coffee beans to develop flavour after roasting is crucial. Resting beans for a while before brewing allows the carbon dioxide (CO2) produced during the roasting process to escape, enabling a fuller and more balanced flavour profile. However, it is important to consume coffee beans within a specific timeframe, typically 1-2 months after roasting, to preserve their freshness and prevent staleness.

Brewing Method

How you brew coffee also has a substantial impact on its final flavour. French press, pour over, espresso, aeropress, drip each provide a different experience. Finding a brewing method that suits your preferences is a crucial first step in exploring the variety of coffee flavours.

Brewing Variables

Details such as water temperature, the ratio of water to coffee, and brewing equipment play a crucial role in creating the desired flavour profile. Adjusting these variables can make a significant difference in the final quality of your cup of coffee.

Our view at Terminal 3 Coffee Roasters is that every cup of coffee is a sensory journey through the diversity of flavours that reflects the richness of the coffee world. By understanding these factors, you can delve into a deeper coffee experience, discovering flavours that match your unique taste. Happy brewing!
