Frequently asked questions
How much caffeine is in a shot of espresso?
About 63 mg per single 1 oz shot, so a double is roughly 125 mg. Amounts vary with the bean, roast, and dose, but a single shot is a good rule of thumb.
How much caffeine is safe per day?
The FDA considers up to 400 mg a day — about four cups of brewed coffee — safe for most healthy adults. Pregnant people are generally advised to stay under ~200 mg. Tolerance varies, so listen to your body.
Does espresso have more caffeine than drip coffee?
Per ounce, yes — espresso is far more concentrated. But by the cup, a big mug of drip usually has more total caffeine than one espresso shot, simply because you drink much more of it.
How much caffeine is in decaf?
Decaf isn't caffeine-free — an 8 oz cup has roughly 2 to 5 mg versus about 95 mg for regular. Tiny, but it adds up over several cups.
Caffeine sensitivity, sleep, and heart conditions differ from person to person. If caffeine affects your sleep, anxiety, or health, talk to a doctor about what's right for you.
