How Much Caffeine Is in a Cup of Coffee?

Caffeine is probably the reason most of us start the day with coffee — but the amount in your cup varies more than you'd think. Here's a realistic breakdown.

Typical caffeine by brew

• Drip coffee (8 oz): roughly 95–165 mg
• Pour-over (8 oz): roughly 90–150 mg
• French press (8 oz): roughly 80–135 mg
• Espresso (1 oz shot): roughly 60–75 mg
• Cold brew (8 oz): often 150–240 mg, since it's brewed strong

Does dark roast have less caffeine?

Barely. Roast level has a very small effect on caffeine. By weight, light and dark are nearly identical; by scoop, dark roast beans are a touch less dense, so you might get marginally less. The bigger factors are how much coffee you use and how it's brewed.

What actually changes the number

Dose (more grounds = more caffeine), brew time and temperature, grind size, and cup size all matter more than roast. A big mug of strong cold brew can easily have two to three times the caffeine of a single espresso.

Enjoy it fresh

However you take your caffeine, fresh beans make the cup worth drinking. Explore our freshly roasted coffees.
