If you’re standing in front of a shelf and the bag tells you ‘Medium-Dark roast,’ what does that actually mean for your cup tomorrow morning? Here’s what every roast level tastes like and when to use it.<\/em><\/p>\n\n\n\n When green coffee beans hit the roaster, they go through a chemical transformation \u2014 sugars caramelize, acids develop, oils migrate. Roasters measure the level by bean color<\/strong> (using an instrument called the Agtron) and by time + temperature<\/strong> in the drum.<\/p>\n\n\n\n Three landmarks during roasting:<\/p>\n\n\n\n Myth 1: ‘Dark roast has more caffeine.’<\/strong> False. Roasting burns off<\/em> caffeine. A light roast has slightly more caffeine per bean. The difference is small but real.<\/p>\n\n\n\n Myth 2: ‘Espresso has to be a dark roast.’<\/strong> Italian tradition uses dark, but specialty espresso uses medium and even light roasts. Modern espresso machines extract well from any roast \u2014 the choice is about flavor, not necessity.<\/p>\n\n\n\n All roast levels have similar antioxidant levels, with light roasts containing slightly more chlorogenic acids. Health-wise the difference is minimal \u2014 the bigger factor is freshness and brew method.<\/p>\n\n\n\n Dark roasts pushed too far into second crack develop char-like flavors. If your dark roast tastes like ashtray, the roaster pushed it too hard \u2014 try a medium-dark instead.<\/p>\n\n\n\n You can, but it’ll taste sour and thin. Moka pots benefit from the body of a medium-dark roast. Save your light roast for filter methods.<\/p>\n\n\n\nWhat ‘roast level’ actually measures<\/h2>\n\n\n\n
