What Is a Doppio? Double Espresso Explained

A doppio is one pull through a double basket with roughly twice the grounds, so the puck is deeper and more even. That changes more than volume:

• Steadier flow: single baskets are shallow and tapered, so small errors in dose or tamp cause channeling; a double is easier to dial in and repeat.
• Milk drinks: a single gets lost in a large volume of milk.
• Equipment: modern baskets are built around about 18g.

If you want less coffee, many cafés split a double into two cups rather than pull a true single, and at home a split-spout portafilter does the same. The espresso ratio calculator turns your dose into a target shot weight.

A double espresso usually contains somewhere around 120–150 mg of caffeine, but the real figure depends on the beans, the dose and the extraction. Robusta-heavy blends contain much more caffeine than 100% arabica, and a larger dose naturally contains more. Roast level makes less difference than many people think.

For comparison, a typical mug of drip coffee often contains a similar or larger amount of caffeine in total, even though each sip tastes less intense. If you are watching caffeine, track the number of shots across the day rather than the size of each drink. Our caffeine calculator estimates caffeine for common drinks.

If you are sensitive to caffeine, a single shot or a decaf espresso still gives you the ritual and flavour.

Full breakdown in coffee drink differences.

Most café milk drinks, from cortados to large lattes, use a doppio as their base.

Most of the drinks in our guide to alternative espresso drinks start from a doppio, and so does a properly made americano.

• Most cafés: "espresso" already means doppio.
• Italian bars: "un caffè" is a single; ask for "un caffè doppio".
• Drink it quickly: crema breaks down within a minute or two.

• Dose: 18g of freshly ground coffee, weighed.
• Yield: 36–40g (about 1:2). Tighter leans ristretto, longer leans lungo.
• Time: about 25–30 seconds, at around 93°C (199°F) and 9 bar.
• Adjust: sour or thin, grind finer; bitter or dry, grind coarser.

Level the grounds and tamp straight before each shot. Everything else, from puck prep to fixing shots that run fast or slow, is in how to dial in espresso; the espresso dial-in calculator tells you what to change after each shot.
