Caffeine Content Database

A standard 8 oz cup of drip coffee contains about 95 mg of caffeine, but the amount varies widely depending on the brewing method and serving size. Espresso has about 63 mg per shot, while cold brew can have 155-215 mg per serving. French press averages 107 mg and pour over around 120 mg per 8 oz cup.

Among common drinks, Bang and Reign energy drinks have the highest caffeine content at 300 mg per 16 oz can. For coffee, a 16 oz Nitro Cold Brew has about 215 mg and a 16 oz Cold Brew has about 205 mg. Among smaller servings, 5-Hour Energy packs 200 mg into just 2 oz.

Yes, decaf coffee is not completely caffeine-free. An 8 oz cup of decaf typically contains about 7 mg of caffeine. While that is a small amount compared to regular coffee (95 mg), it can add up if you drink several cups. People who are highly sensitive to caffeine should keep this in mind.

Tea generally contains significantly less caffeine than coffee. An 8 oz cup of black tea has about 47 mg of caffeine, compared to 95 mg for drip coffee. Green tea is even lower at 28 mg. However, matcha is an exception at 70 mg for a 2 g serving, since you consume the whole leaf. Herbal teas are naturally caffeine-free.
