What do brew ratios determine in coffee preparation?

Brew ratios play a critical role in defining the strength and flavor balance of the final cup of coffee. The brew ratio is the relationship between the amount of coffee grounds used and the amount of water added during preparation. A well-calibrated brew ratio ensures that the extraction process yields optimal flavors from the coffee grounds.

When the ratio is appropriately adjusted, it can enhance certain flavor notes and deliver a balanced cup, promoting desirable characteristics such as sweetness, acidity, and body. For example, a higher coffee-to-water ratio generally results in a stronger brew, while a lower ratio can create a lighter, more diluted flavor profile. Thus, mastering brew ratios is essential for crafting a coffee experience that meets the preferences of the drinker, making this choice the correct answer.
