What is the common ratio of coffee to water for drip brewing?

The common ratio of coffee to water for drip brewing is indeed between 1:15 to 1:18. This range is generally accepted as the ideal balance for extracting the flavors and aromas of the coffee without leading to over- or under-extraction. When coffee is brewed within this ratio, it typically results in a well-rounded and flavorful cup, as it allows the water to adequately extract the soluble compounds from the coffee grounds.

Using a ratio of 1:15 is often desired for a stronger flavor, while 1:18 is more suitable for those who prefer a milder taste. This flexibility lets Brewistas tailor the coffee to individual preferences while adhering to standards that produce consistently good results.

In contrast, other ratios, such as those with higher proportions of water to coffee, such as those found in options suggesting 1:20 or above, may lead to a weaker flavor profile. Likewise, ratios that use a significantly less amount of water than suggested can result in overly concentrated coffee that may taste bitter or harsh. Hence, the range of 1:15 to 1:18 is recognized as optimal for drip brewing techniques.
