Start with a baseline
Record your beans, grinder setting, dose, yield, and shot time. Keep the starting point simple enough to repeat.
Find your sweet spot.
Remember the way back.
Great espresso takes a few small adjustments. Give each one a place to live, so a promising shot becomes a recipe you can come back to.

Taste before you tweak
A number can’t tell you whether you enjoyed the shot. Add your impressions, then change one variable and record the difference.
Keep the shot that worked
Save the details when you find a cup you like. Revisit them when you open the same coffee, and adjust as the beans age.
Frequently asked questions.
What does espresso dial-in mean?
Dialling in means adjusting your recipe and grind to get the flavour you want from a coffee. Keep a record so you can compare the result of each change.
Does the app control my espresso machine?
No. Coffee Book helps you record and refine your brew. You still control your machine and grinder.
Is 1:2 always the right espresso ratio?
No. It is a useful starting point for many coffees, not a rule. Different beans, baskets, roast levels, and tastes can call for a different yield.
