What is the optimal temperature range for brewing coffee?

The optimal temperature range for brewing coffee is indeed between 195°F to 205°F. This temperature range is crucial because it allows for the extraction of the coffee's flavors and aromas without bringing out excessive bitterness or undesirable compounds. Brewing at temperatures lower than 195°F may result in under-extracted coffee, which can taste sour or weak, while brewing at temperatures above 205°F risks over-extraction, leading to a harsh or burnt taste. This balance is essential for achieving a well-rounded cup of coffee with a full spectrum of flavors.

In contrast, the other choices suggest brewing temperatures that do not facilitate the best extraction process. For example, temperatures of 175°F to 185°F are too low, potentially leading to under-extracted coffee. Similarly, brewing at 210°F to 220°F exceeds the optimal range and can result in undesirable flavors that compromise the drink's quality. The other option of 180°F to 190°F also falls short of the ideal range needed for effective coffee brewing, affecting the richness and complexity of the final brew.
