How do I dial in my espresso?

Dialing in means adjusting your recipe until the shot tastes balanced. Start with a 1:2 ratio, pull a shot, and taste it. Then adjust one variable at a time. Grind size has the biggest effect on extraction, so make small changes for a clear read on every shot.

Why is my espresso sour or bitter?

A sour shot points to under extraction, so grind finer or raise the water temperature a few degrees. A bitter shot points to over extraction, so grind coarser or lower the temperature. Fresh beans around 7 to 21 days off roast also pour best.

Q: What is a good espresso ratio?

A good starting espresso ratio is 1:2, which is 18 grams of coffee in for about 36 grams of espresso out. Lighter roasts often taste better at a longer 1:2.5 ratio, while darker roasts can shine at a shorter 1:1.5 ratio.

A sour or weak shot usually means under extraction. Grind finer or raise the water temperature a few degrees. A bitter or harsh shot usually means over extraction. Grind coarser or lower the temperature. Change one variable at a time. Small steps give you a clean read on every shot.

Quick Espresso Troubleshooting Chart

Sour and thin: grind finer, increase dose, or raise temperature.
Bitter and dry: grind coarser, reduce dose, or lower temperature.
Shot runs too fast (gusher): grind finer or tamp level.
Shot runs too slow (choked): grind coarser or reduce dose.

Fresh beans matter too. Coffee around 7 to 21 days off roast tends to pour best. Re-check your grind when you open a new bag.
