Single vs Double vs Triple Espresso Baskets.
Single vs double basket espresso: a single basket holds about 7–9g of coffee, a double about 14–20g (18g is the modern standard), and a triple about 20–22g. Most baristas use the double for everything, including a single drink, because it's easier to prep evenly and more forgiving.
A double basket doesn't make "two shots." It makes one shot from a bigger dose, which is the one the rest of our espresso advice is built around. The basket sets how much coffee the shot has to work with; your dose and yield do the rest.
01.The three basket sizes
Dose is the dry coffee you put in; yield is the liquid that comes out. At a 1:2 ratio, yield is about double the dose — see our dose guide.
| Basket | Dose in | Yield out at 1:2 | Best for | Catch |
|---|---|---|---|---|
| Single | ~7–9g | ~14–18g | A small, concentrated drink | A shallow bed; small prep errors show up fast |
| Double | ~14–20g (18g modern) | ~28–40g (~36g at 18g) | Nearly everything — the default | None worth worrying about |
| Triple | ~20–22g | ~40–44g | Larger drinks or higher-dose recipes | Mostly a 58mm basket; rare on smaller machines |
02.Why the double is the default
A bigger dose gives you a deeper, more forgiving coffee bed, so small flaws in grind or distribution show up less. A single basket is shallow, which magnifies the same flaws and can lead to channeling. That's why even a single drink is usually pulled from a double basket.
The double also keeps your recipe consistent. The 25–30 second timing in our shot time guide is built around a double.
03.When a single or triple makes sense
A single basket suits someone who really wants a small, strong drink and doesn't want to waste coffee, and it can work well once your prep is good. A triple suits higher-dose recipes and bigger drinks, but it needs a basket and portafilter that fit: they're mostly a 58mm thing, and 54mm and 51mm machines usually top out at a double. See our 54mm vs 58mm guide.
For most people the practical advice is simple: use the double, weigh the dose, and move on.
04.Match the dose to the basket
Every basket has a dose it was designed for, usually printed on it or in the manual. Underfilling leaves headspace and a loose puck; overfilling compresses it unevenly and can press against the shower screen. Either invites channeling.
Weigh the dose every time — a basic scale costs about as much as a bag of beans, and our accessories guide covers what to buy.
FAQ
- What's the difference between single and double espresso baskets?
- Size. A single holds about 7–9g of coffee and a double about 14–20g. The double produces one larger shot and is the standard choice because it's more forgiving.
- How many grams does a double basket hold?
- About 14–20g depending on the basket, with 18g the modern standard. Check the number printed on your basket or in the manual.
- What is a triple basket for?
- Higher-dose recipes and larger drinks, around 20–22g. They're mostly made for 58mm portafilters and are uncommon on smaller machines.
- Can I use a double basket for one drink?
- Yes, and most baristas do. A single drink from a double basket is easier to prep evenly than one from a shallow single basket.
