Brewing coffee at incorrect temperatures can have a significant impact on the final taste and quality of the brew. Incorrect temperature can lead to under-extraction or over-extraction, resulting in a bitter or sour taste. Additionally, brewing at too low of a temperature can result in a weak or watery flavor, while brewing at too high of a temperature can result in burnt or unpleasant flavors.
Under-Extraction
Under-extraction occurs when the brewing temperature is too low, and the coffee compounds are not fully dissolved into the water. This can result in a weak brew with a lack of flavor and aroma. The coffee may taste sour or acidic, as the desirable flavors haven’t been properly extracted.
Over-Extraction
Conversely, over-extraction happens when the brewing temperature is too high, and the coffee compounds are extracted too quickly and excessively. This can result in a bitter and unpleasant taste. Over-extracted coffee may also have a burnt or smoky flavor due to the breakdown of coffee compounds at high temperatures.
Bitter or Sour Taste
Brewing coffee at incorrect temperatures can also lead to a bitter or sour taste. When brewing at too high of a temperature, the coffee can become overly bitter, as undesirable compounds are extracted. Similarly, brewing at too low of a temperature can result in a sour taste, as acidic compounds are not properly balanced with the sweetness of the coffee.
Weak or Watery Flavor
Brewing at a temperature lower than the recommended range can result in a weak or watery flavor. Inadequate extraction at low temperatures fails to bring out the full spectrum of flavors, leading to a lackluster and diluted brew. To achieve a rich and flavorful cup of coffee, it is essential to brew within the optimal temperature range.
Coffee Roast Level and Brewing Temperature
