Does espresso have more caffeine than coffee?
Last updated September 3, 2026.
Espresso has more caffeine per ounce, but the tiny serving means a regular coffee usually has more caffeine total. Mayo Clinic's chart: a 1-ounce espresso shot is about 63 milligrams; an 8-ounce brewed coffee about 96. The FDA puts a 12-ounce brewed coffee at 113 to 247 milligrams depending on beans and brew. Espresso's intense taste is concentration, not total dose. Count shots and cups, and keep all sources inside the FDA's 400 milligram daily guide for most adults. If you are caffeine-sensitive, even a single late-afternoon shot can cost you sleep.
What to do
- Count shots, not intensity: a double latte is roughly 126mg, less than a big drip.
- Watch the large brewed coffees; a strong 12-ounce can top 200mg.
- Keep the daily total under 400mg across coffee, tea, energy drinks, and cola.
- Cut off earlier if you are sensitive; the numbers matter less than your own reaction.
