How much caffeine is in a cup of coffee?
It depends on the brew method. A standard 8 oz drip coffee contains about 95 mg of caffeine. An espresso shot (1 oz) has roughly 63 mg. Pour-over runs around 80 mg per 8 oz, French press around 107 mg, and cold brew around 155 mg per 8 oz.
What is the safe daily caffeine limit for adults?
Health authorities including the FDA and European Food Safety Authority recommend a maximum of 400 mg of caffeine per day for healthy adults — roughly 4 drip coffees or 6 espresso shots. Pregnant individuals are advised to stay under 200 mg per day.
Which brew method has the most caffeine?
Cold brew has the highest caffeine per fluid ounce at around 155 mg per 8 oz. French press is next at ~107 mg. Espresso is highly concentrated (63 mg per 1 oz shot) but typically consumed in smaller volumes than drip coffee.
Does roast level affect caffeine content?
Very little. Contrary to popular belief, dark roasts lose a tiny bit of caffeine during roasting but the difference is negligible — well under 1%. Caffeine content is primarily determined by brew method, dose, and water ratio — not roast level.
