Frequently Asked Questions
What is a good espresso brew ratio?
Ristretto shots are typically 1:1 to 1:1.5, normale shots are around 1:2, and lungo shots range from 1:3 to 1:4.
Does brew time matter if I hit my ratio?
Yes. Even with the correct ratio, a shot that pulls too fast or slow usually indicates your grind size needs adjustment.
Should I weigh my dose every time?
For consistency, weighing both dose and yield is the most reliable way to replicate a great shot.
