Moka pot coffee averages 93 mg of caffeine per 2 fl oz serving, or about 46 mg per fluid ounce, on Caffeine Informer's tests. That makes a Bialetti "cup" (2 oz) roughly 93 mg and a full 3-cup Moka Express (4.4 oz) about 205 mg.
The confusion with moka pots is the word cup. A moka cup is an espresso-sized pour, not a mug. Bialetti's own sizing guide puts it plainly: 1 cup = 2 oz, 3 cup = 4.4 oz, 6 cup = 9.1 oz, 9 cup = 14.2 oz, 12 cup = 22 oz, 18 cup = 27.3 oz. So a "6-cup" pot holds a bit more than one American mug, and if you drink the whole thing you are drinking six espresso-sized servings of a brew that is stronger than drip.
Caffeine by Bialetti pot size
| Moka Express size | Yield (Bialetti) | Caffeine at 46.5 mg per oz |
|---|---|---|
| 1 cup | 2 oz | about 93 mg |
| 3 cup | 4.4 oz | about 205 mg |
| 6 cup | 9.1 oz | about 425 mg |
| 9 cup | 14.2 oz | about 660 mg |
| 12 cup | 22 oz | about 1,020 mg |
Yields from Bialetti's product page. Caffeine is our arithmetic: Bialetti's yield multiplied by the 46.5 mg per fl oz figure on Caffeine Informer's moka pot page, which is the average of three test brews normalized to a 50 ml serve. Your pot will land above or below it depending on grind, dose and how long it runs.
Where moka sits between espresso and drip
Per ounce, moka coffee is well under espresso and well over drip. USDA lists restaurant-prepared espresso at 212 mg of caffeine per 100 g, about 63 mg per fluid ounce, and brewed coffee at 40 mg per 100 g, about 12 mg per fluid ounce. Moka at 46 mg per ounce is closer to espresso in concentration, which is why a 4.4 oz pot carries about as much caffeine as a 16 oz drip (roughly 190 mg on the USDA rate). It is also why moka pots do not make espresso: the pressure is far lower and the extraction longer, and the numbers show it.
What raises or lowers it
Brew time is the one Caffeine Informer flags: the longer the pot runs, the more caffeine comes across, so a pot left sputtering on high heat extracts more than one pulled off the flame as soon as the stream turns pale. Dose is fixed by the basket, since a moka basket is meant to be filled level, but a fine grind extracts more than a coarse one. Blend matters more than any of that: robusta-heavy Italian blends, which is most of what gets sold for moka use, carry more caffeine than 100 percent arabica.
Reading the pot size honestly
A 3-cup pot is a normal single serving in Italy and lands near a double-shot americano. A 6-cup pot drunk by one person is a different thing: on the test average it runs past the 400 mg figure below in one sitting. If you brew a 6-cup and drink it alone, you are not having a cup of coffee, you are having two large ones. Splitting it, or buying the 3-cup, is the easy fix. The AeroPress vs moka pot page covers how the two brewers compare on taste and effort.
For context, the FDA cites 400 mg of caffeine a day as an amount not generally associated with negative effects in healthy adults. That is information, not advice. How caffeine affects you depends on your own tolerance and health.
