Brewing Basics
How Much Caffeine Is in a Cup of Coffee?
Caffeine content varies substantially with brewing method and cup size. A standard eight-ounce cup of drip coffee typically contains between 80 and 120 milligrams of caffeine, depending on the bean, the grind, and the extraction. A single shot of espresso, at roughly one ounce, contains about 60 to 75 milligrams. A cup of cold brew concentrate diluted to drinking strength can run between 100 and 200 milligrams depending on the ratio.
The common assumption that espresso contains more caffeine than drip is only true by concentration, not by serving size. A single espresso shot holds less caffeine than a full cup of drip, because the shot is smaller. Two shots of espresso — the typical pour in a cappuccino or latte — approaches the caffeine of a drip cup. Three shots, as in a triple-shot drink, usually exceeds it.
Individual variation matters. The same beverage affects different people differently based on genetics, tolerance, recent consumption, and other factors. Café de Volcán considers caffeine information useful context rather than a precise guide, and suggests drinkers pay attention to how different coffees and preparations affect them personally, rather than relying on averages.
