PHYSICOCHEMICAL CHARACTERISTICS OF WATER

Water is a molecule made up of one oxygen and two differentially charged hydrogen atoms (H2O), resulting in an unequal distribution of electrical charge (see Fig. 16.1), which is known as polarity. Water is an excellent solvent for polar substances due to its polar nature, as seen during coffee extraction. It, on the other hand, barely dissolves nonpolar molecules like oils and fats, which account for more than 10% of the weight of roasted coffee. The solubility of nonpolar substances …

GRINDING COFFEE

The goal of grinding the beans before brewing is to expose enough surface area to extract enough flavor from the beans to make a nice cup of coffee. You'd get a very weak brew if you brewed whole beans. The finer the beans are ground, the more surface area is exposed, and the coffee should brew faster in theory because the water has more access to it. When determining how finely the coffee should be ground for various brew processes, …

TASTING AND DESCRIBING COFFEE

Tasting takes place in two places: our lips and our noses, and it's essential to think about these two aspects of the process independently while learning to taste and talk about coffee.
