Typically, the recommended brewing temperature for most coffee brewing methods ranges between 195°F to 205°F (90°C to 96°C). At this temperature range, a harmonious balance is achieved between sweetness, bitterness, acidity, and body.

When brewing coffee at lower temperatures, there is a tendency for the extraction of soluble compounds to slow down, which can lead to a diminished flavor profile. As a result, the coffee may taste more acidic and under-extracted, lacking the richness and sweetness that can be unlocked through higher temperatures. For example, brewing with light roast beans at around 185°F (85°C) may result in an overly bright and tangy cup, which might not provide the fuller spectrum of flavors like those found in darker roasts.

Conversely, brewing coffee at higher temperatures can enhance the extraction of oils and solids, leading to a more robust and fuller-bodied cup. However, excessively high temperatures can also extract undesirable bitter compounds, overshadowing the coffee’s natural sweetness. For instance, medium roast coffees generally thrive at a temperature of around 200°F (93°C), allowing for an optimal balance of flavor without overpowering the natural characteristics of the bean.

Understanding the relationship between brewing temperature and flavor is essential for coffee enthusiasts seeking to refine their brewing techniques.
