Frequently Asked Questions
What is a good espresso brew ratio?
Most espresso shots fall between 1:1.5 (ristretto) and 1:3 (lungo), with 1:2 being a common balanced starting point.
What does a longer shot time mean?
If your shot runs longer than your target time, your grind is likely too fine or your dose too high; if it runs faster, try a finer grind.
Does dose weight matter?
Yes, dose weight along with ratio determines your final yield weight, which directly affects strength and flavor balance.
