Brewer and cup size
Pick the device first, then a realistic batch size for that brewer.
A familiar baseline for batch-brew coffee at home, where consistency matters more than drama.
Drink size
Water target: 237 g · 8 oz · 237 ml
Brew strength
Strength here means the coffee-to-water ratio, not how dark the roast is.

Roast and water temperature
Roast level mostly moves the starting water temperature. The cup still decides the final tweak.
Start at 194-200°F / 90-93°C for a medium roast. Adjust only after tasting.
Brew pace
Faster brews usually drink lighter; slower brews push toward more extraction and more weight.

What it does
Gives you a starting recipe for water, coffee dose, temperature, grind direction, and brew pace.
What it is not
Not a magic recipe. It gets the first cup close so tasting and adjustment become easier.
Working rule
Change one variable at a time after the first brew. Otherwise the cup stops teaching you anything.
After the first cup
Sharp and thin? Move one step stronger or grind slightly finer.
Heavy and drying? Move one step lighter or grind slightly coarser.
Keep water and dose stable while you test. That is how the brew starts making sense.
Keep going
Turn the number into a cup.
The ratio sets the starting point. Brewing method, grind and water decide the rest of the cup.
