Drink Recipe
18g coffee → 36g espresso
Simple Method
Bloom with about 2–3× the coffee dose, then pour slowly until you reach the target water amount.
Taste Adjustment
Start with the suggested setting. If the cup tastes sour or drains too fast, move one step toward FINE. If it tastes bitter, dry, or drains too slowly, move one step toward COARSE.
This brew plan is a starting point based on MAXA testing and common specialty-coffee brewing references. Final adjustments should be made by taste, brew time, roast level, and your coffee beans.

Adjust by Taste
Small changes make a big difference.
Too Sour?
Move one step toward FINE.
A sour cup often means under-extraction or too fast of a flow.
Espresso
Move one step toward COARSE.
Bitterness often comes from over-extraction or a brew that runs too slowly.
Flow Too Fast?
Move toward FINE.
A finer grind slows the water flow and increases extraction.
Flow Too Slow?
Move toward COARSE.
A coarser grind improves flow and reduces clogging.
Why Grind Size Matters
Grind size directly affects extraction.
• A finer grind can slow down water flow and increase extraction.
• A coarser grind can speed up flow and reduce over-extraction.
The right setting helps you find better balance, clarity, and sweetness in the cup.
