Many coffee enthusiasts have heard of the three terms "original extraction," "fine extraction," and "full extraction," but are not quite clear on what exactly distinguishes them, nor why these options are almost never seen in specialty coffee shops. In fact, they correspond respectively to Normale, Ristretto, and Lungo in espresso—that is, regular espresso, short-extraction espresso, and long-extraction espresso. The core differences among the three center on concentration and flavor expression: different brew ratios lead to changes in the extracted coffee's concentration and extraction yield. This article uses Front Street Espresso Blend · Strawberry Candy Espresso as an example to break down the extraction parameters and flavor characteristics of the three espressos one by one, and explains why specialty coffee shops rarely offer multiple espresso type choices—this involves both the practical difficulty of grind size adjustment and the compatibility of different espressos in milk coffee.
