Less guesswork.
More flavor.
Good espresso takes a little attention. Keep track of what you change and what you enjoy.
Taste your espresso.
Measure your shot and note how it tastes. Too sour, too bitter, or just right? What you taste guides your next step.
Refine your grind.
Your taste notes and shot data lead to a specific recommendation, such as grinding a little finer. Try another shot and compare.
Save your recipe.
Turn a great shot into a recipe saved with your beans. Grind setting, dose, and target yield stay together. Next time, start with your saved settings.
