How much caffeine is in Turkish Coffee?

Turkish coffee is tiny but mighty, packing about 50 mg of caffeine into a concentrated 2 oz cup. Brewed unfiltered with finely ground beans, it delivers a coffee's worth of kick in a few small sips.

Small (~2 oz) but concentrated; ~25–60 mg per cup.

Will Turkish Coffee affect your sleep?

At 50 mg, a cup sits right at the sleep-threshold and dips below it within an hour. An afternoon Turkish coffee is usually clear by bedtime, though doubling up brings it closer to a full mug.
