Raw coffee beans can only release those thousand-plus aromatic compounds and become a fine brew in the cup after roasting. During heating, substances such as sugars and lipids undergo Maillard reactions and caramelization, while the coffee bean fibers gradually carbonize, ultimately approaching a charcoal-like state. Based on the degree of carbonization and surface color, the industry classifies roast levels into three major categories: light, medium, and dark. Under different roast levels, the amount of precursor aromatic substances retained in coffee beans and the degree of fiber caramelization differ, resulting in distinctly different acid-bitterness balance and regional flavors. Light roasts are bright with acidity and aroma, medium roasts are balanced with nutty and creamy notes, and dark roasts are full-bodied with interwoven bitterness and sweetness. Starting from the principles of chemical reactions, this article will break down the flavor characteristics of the three roast levels one by one, recommend representative Front Street specialty coffee beans for each roast level, and also discuss which roast level is more in line with health considerations, providing a reference for coffee lovers' daily purchasing decisions.
