What each ratio is called and where it shines.
| Ratio range | Name | Character | Best for |
|---|---|---|---|
| 1:1 to 1:1.5 | Ristretto | Concentrated, heavy, sweet | Dark roasts, milk drinks |
| 1:1.5 to 1:3 | Normale | Balanced, classic, clean | Single / double / triple shots (1:2 default) and turbo shots (1:2 to 1:3) |
| 1:3 to 1:4 | Lungo | Long, extended extraction | Light and medium-light roasts |
| 1:4+ | Very lungo | Close to filter territory | Very light or Nordic-style roasts |
A brew ratio is the ratio of dry coffee going in to liquid espresso coming out. Both measured in grams. If you dose 18g of ground coffee and pull 36g of espresso into the cup, your ratio is 1:2.
Ratios affect taste because they govern how much water passes through the puck. A short shot (low ratio, like 1:1.25) extracts less, giving you a dense, sweet, concentrated ristretto. A long shot (high ratio, like 1:3 to 1:4) extracts more, giving you a lighter, brighter, more delicate lungo.
The modern default is 1:2, whether you are pulling a single, double or triple shot. It is the most forgiving starting point and suits the majority of beans. From there, adjust up for lighter roasts (they benefit from more extraction) and down for darker roasts (which already have big flavour and risk going bitter with too much extraction).
For a deeper treatment of how ratio interacts with grind size and taste, see Espresso brew ratios explained.
Not every shot is defined by ratio alone. These are the other styles PUCK YEAH! tracks in the app.
Categorised by dose size, not ratio. All default to 1:2. Single = ~7-9g dose. Double = ~14-20g. Triple = ~21-25g. Pick by what your basket takes and how much caffeine you want.
Modern style. Very fine grind pulled fast (12-18 seconds) for a higher ratio. Produces a sweet, bright cup with less bitterness. Popular with light roasts on prosumer machines.
A diluted espresso. Pull a normale shot then add hot water to the cup. Different from a lungo because the extraction itself is standard; only the final drink is diluted. French cafe staple.
Not a ratio, a verdict. The rare shot where everything aligns. The bean is fresh, the grind is dialled, the pour is even, the crema is perfect and the taste is unreal. Label it, learn it, try to repeat it.
All of these are taggable in the PUCK YEAH! app.
A calculator tells you what 36g on 18g means. It doesn't tell you that your current grind is 2 clicks too coarse for the bean you opened on Sunday. Jarvis does.
