Frequently Asked Questions

How much caffeine is in moka pot coffee?

A typical 2oz serving from a moka pot contains approximately 80mg of caffeine. This can vary based on coffee type, grind size, and brew time.

Does espresso have more caffeine than regular coffee?

Per ounce, yes - espresso has about 63mg per ounce vs. 12mg per ounce for drip coffee. However, a full cup of drip coffee (8oz) has more total caffeine (95mg) than a single espresso shot (63mg).

Is 400mg of caffeine a day too much?

For most healthy adults, 400mg per day is considered safe by the FDA. However, individual tolerance varies. Start with less if you're caffeine-sensitive.

Does dark roast have more caffeine?

No, this is a myth. Light roasts actually have slightly more caffeine because the roasting process breaks down caffeine molecules. The difference is minimal though.

How long does caffeine stay in your system?

Caffeine has a half-life of 3-5 hours, meaning it takes this long for your body to eliminate half the caffeine. Full elimination can take 8-10 hours.
