How much caffeine is in Espresso (single shot)?
A single espresso shot delivers about 63 mg of caffeine in barely an ounce, a small cup with a surprisingly full kick. Ounce for ounce it's intense, but the tiny volume keeps the total in the neighborhood of a modest cup of drip.

Will Espresso (single shot) affect your sleep?
With 63 mg, one shot drops below 50 mg within a couple of hours and is largely cleared in five or six. An espresso with dessert is gentler on sleep than most coffees, though late-evening shots can still keep light sleepers alert.
