Q: What is the best ratio for espresso?

The modern standard is 1:2 — 18 g of dry coffee yielding 36 g of liquid espresso in about 25–30 seconds. That's 'normale': balanced, sweet, syrupy. Prefer intensity? Go ristretto at 1:1–1:5 (denser, sweeter, less bitter). Prefer a longer, milder drink? Lungo at 1:3–1:4 . The 1:2 starting point suits most medium-roast specialty coffee; very light roasts sometimes shine at 1:2.5.

Q: What does a 1:2 espresso ratio actually mean?

It means one part dry coffee to two parts liquid espresso, both weighed in grams : 18 g in the portafilter → 36 g in the cup. The 'parts' are mass, not volume — a 36 g shot looks like roughly 45–50 ml because crema is mostly air. Weigh the cup on a scale; volume markings on shot glasses mislead by up to 30%.

Q: Ristretto vs normale vs lungo — what's the real difference?

All three use the same coffee; only the ratio changes. Ristretto (1:1–1:5) stops the shot early: concentrated, sweet, heavy body, lower caffeine per gram. Normale (1:2) is the balanced all-rounder. Lungo (1:3–1:4) runs long: thinner body, more bitterness, higher total caffeine. Grind stays in the same neighborhood — you're changing how much water passes through, not the coffee itself.

Q: How do I measure espresso ratio without a scale?

Honestly: get a $15 scale — it's the highest-ROI upgrade in home espresso. Until then, approximate: a double basket holds ~18 g, and 36 g of espresso looks like about 1.5 oz / 45 ml in the cup (crema inflates volume). Time it too: 25–30 seconds for a 1:2 is the classic sanity check. But every volumetric shortcut drifts; the scale is what makes the ratio real.

Q: Does grind size change the brew ratio?

No — the ratio is weight in vs. weight out , independent of grind. Grind size changes how fast the water flows and therefore the extraction: too fine chokes the shot (slow, bitter), too coarse gushes it (fast, sour). Dial in this order: lock the ratio (start 1:2), then adjust grind to land 25–30 seconds, then taste and move the ratio only if the flavor demands it.

Question 3

What is extraction yield in coffee?

Accepted Answer

The percentage of the coffee's mass that dissolved into the water: extraction % = TDS × beverage weight ÷ dose. The Specialty Coffee Association's golden-cup window is 18–22% extraction at 1.15–1.35% TDS for filter coffee (espresso runs 8–12% TDS). Below 18% tastes sour and thin (under-extracted); above 22% tastes bitter and dry (over-extracted). The TDS tab above computes it from your refractometer reading.
