The act of brewing coffee itself is referred to as oxidation. The moment the beans interact with water, the beans start to release their oils into the liquid, giving you your favorite rich and flavorful cup of Joe in the morning. It is best to avoid oxidation before brewing to get the best-tasting coffee.

Coffee Ice Cubes
