In a cup of black coffee, water makes up the vast majority, so its impact on flavor must not be underestimated. Different brands of drinking water vary in mineral composition, hardness, and pH, so the coffee brewed with them naturally takes on different characteristics. To investigate this variable, Front Street Coffee selected four common drinking waters—Baisui Mountain, Nongfu Spring, Ganten, and C'estbon—and used the same Costa Rica Mozart coffee beans to make cold brew, measuring TDS, coffee liquid concentration, and recording flavor performance one by one. The experiment found that the amount of calcium and magnesium ions in water affects extraction efficiency and taste direction, while Nongfu Spring with medium TDS and C'estbon purified water each showed distinct stylistic differences. This article will present the full experimental process and tasting results, and offer water selection suggestions for different taste preferences. [more…]

Caffeine is the key source of coffee's stimulating effect and an important reason why many people drink coffee every day. However, tolerance to caffeine varies greatly from person to person.

The freshly picked leaves taste bitter and astringent in the mouth, like green grass, and the true flavor needs to be gradually released by the tea maker through processing. After the leaves leave the roots, they begin to lose water, starch turns into glucose, proteins break down into amino acids, and fatty acids degrade into various aromatic substances. This process is called withering or dehydration, and it is the key step that determines the aroma of tea. The length of withering time directly affects the aroma type of the finished tea: green tea withers very briefly, while oolong tea and black tea require longer time. Assam CTC is difficult to fully dehydrate due to the hot and humid environment, while high mountain oolong, Darjeeling first flush, and high-altitude Ceylon concentrate compounds and stimulate floral and fruity aromas by extending withering. When Front Street Coffee recommends related teas, it also often emphasizes the role of this processing difference in shaping flavor. [more…]
