The Secret to Delicious Coffee: "Water"

コーヒーがもっと美味しくなる「水」の秘密

98% of a cup of coffee is water.

The taste of coffee is not determined by the beans alone. In fact, approximately 98% of a cup of coffee is composed of water. No matter how high-quality the specialty coffee beans, the taste can vary greatly depending on the quality of the water. That's why, if you're truly pursuing delicious coffee, a commitment to water is essential.

How Coffee Taste Changes with Soft and Hard Water

Japanese water is generally soft, which is said to be compatible with coffee. Soft water tends to bring out the delicate aroma, sweetness, and fruity acidity of coffee beans, resulting in a well-balanced taste. Hard water, on the other hand, tends to emphasize bitterness and richness, leading to a completely different impression even with the same beans.

Water is Especially Important for Specialty Coffee

Specialty coffee's appeal lies in enjoying the unique characteristics of each region. To maximize the splendid aroma of Ethiopia, the fruitiness of Kenya, or the elegant sweetness of Guatemala, appropriate water is necessary. Differences in water can make the inherent charm of the beans even more vivid.

Temperature is Also an Important Factor that Affects Taste

Not only water quality, but also the temperature during extraction is important. Generally, 90-96℃ is considered ideal; if too high, bitterness will be strong, and if too low, insufficient components will be extracted. By adjusting the temperature according to the characteristics of the beans, you can get closer to a more ideal cup.

Water Quality at Home

In recent years, more and more people are using water purifiers or mineral water specifically for coffee. Even with the same beans, you might be surprised by the difference in taste just by changing the water. For coffee lovers, it's worth experiencing the difference in taste due to water at least once.

The Best Cup Starts with Water

Coffee isn't complete with just good beans. High-quality beans, appropriate roasting, careful extraction, and high-quality water. Only when all of these come together can an amazing cup be created.

Next time you drink coffee, try paying attention to the "water." Your usual coffee might transform into an even richer and deeper flavor.The ultimate coffee experience begins with a commitment to water.
