BIAB calculator

In my first steps into beer brewing, I was looking for a easy tool to start making my own Beer recipes.

Since I use a simple Brew In A Bag system, which I also don’t really plan on upgrading any time soon. Aside from the pot and stove, I wanted something that was tailored to this, and following the K.I.S.S method, or keep it simple stupid.

I am homebrewing here for friends, family, and most of all myself. So no need to complicate it needlessly.

Beer is: Art, History, and Culture.

🍺 BIAB Recipe Builder & Calculator

Loading a recipe fills in the grains, hops, yeast, mash profile and boil time below, scaled to your current batch volume. Everything remains fully editable afterwards.

Enter a percentage and click "Apply" to proportionally rescale all grain weights below to reach the desired ABV, while keeping the ratios between the grains intact.

🌾 Grains & Malts

Grain / Malt Type Weight (g) Share (%)
Total grain bill 100%

Edit a share (%) to rebalance the other grains while keeping the total weight, or edit the total to scale the whole grain bill. New grains start at 0%.

🌿 Hops

Current bitterness0 IBU
Style range-
Balance (BU:GU)0.00

Pick a style to see its typical bitterness range and set a target IBU. "Apply to Hops" rescales all hop additions below proportionally to reach the target, keeping the ratio between them. The ranges are guidelines, not strict style rules.
