Coffee Brewing Starter
Start a new bag without guessing.
Choose your brew method, roast level, and water amount. Measured Bloom will give you one repeatable first brew for ratio, grind, and temperature — then you can let taste decide what changes next.
Your first-brew baseline
18 g coffee + 300 g water
Pour over · medium roast · 1:16.7
Brew this baseline once. If the cup tastes off, keep the recipe steady and use the Brew Troubleshooter to choose one next change.
Keep the same dripper, filter, pouring pattern, and water amount for the next brew so taste can guide one clean adjustment.
Why the starter begins at 1:16.7
The Specialty Coffee Association describes 60 grams of ground coffee per liter of water as a commonly used brewing ratio for drip and immersion coffee. That is 1 gram of coffee for every 16.7 grams of water. Measured Bloom uses it here because the first brew needs a stable reference more than it needs a supposedly perfect number.
Why the tool changes temperature before changing the ratio
Roast level can shift a useful starting temperature by a few degrees, while the ratio stays fixed so you do not move several variables before tasting the coffee. Lighter roasts start a little hotter and darker roasts a little cooler in this tool. The next adjustment still comes from the cup, not from the label on the bag.
Why grinder numbers are not shown
Grinder settings are not standardized across brands, models, burrs, calibration points, and even individual grinders. The starter gives a relative grind zone such as medium-fine or coarse. Use the Grind Size Finder after the first brew if you need to move finer or coarser from taste and brew behavior.
Coffee Brewing Starter FAQ
What ratio does the Coffee Brewing Starter use?
It begins at 1:16.7, equal to 60 grams of coffee per liter of water. The Specialty Coffee Association describes 60 g/L as a commonly used brewing ratio for drip and immersion coffee.
Why does the starter not include espresso?
Espresso is better described by dry dose, beverage yield, shot time, basket type, puck preparation, flow, and taste. Measured Bloom handles those variables in the Espresso Dial-In Assistant instead of forcing espresso into a filter-coffee starter recipe.
Why does the starter not include cold brew?
Cold brew commonly uses very different ratios and may be brewed as concentrate or ready-to-drink coffee. The Cold Brew Calculator keeps brewing ratio and post-brew dilution separate.
Is this supposed to be the perfect recipe?
No. It is a repeatable first brew. The point is to establish a useful baseline, taste it, and then change one variable at a time.
