PURPLEFLOW / COFFEE

Stop guessing your coffee dose

A repeatable hot-filter brew starts with measured coffee and water—not a mug’s “cup” marking.

PURPLEFLOW / COFFEE

Read 1:16 correctly

That means 1 g dry coffee for every 16 g brewing water. It is a starting point, not a universal best.

PURPLEFLOW / COFFEE

Try 20 g + 320 g

Weigh 20 g coffee. Add 320 g water in total, including the bloom. Expect less finished drink.

Your mug is not a measuring cup

Machine “cups,” measuring cups and mugs differ. Measure the water you add, then scale your recipe.

Change one thing

Keep dose and water steady while testing a small grind adjustment. Strength and extraction are different.

Make the next cup repeatable

Record coffee, total water and one taste note. Keep what works; adjust one variable next time.
