Brew Day Planner

How it works. Water volumes come from our equipment profile for each system, the same numbers as our BeerSmith profiles. Gravity uses each malt’s typical extract and your efficiency; bitterness uses the Tinseth formula, with whirlpool hops counted at half a 5-minute addition; colour uses the Morey formula. Heat-up times assume about 80% of the element’s power reaches the water, with the lid on. Every system boils off a little differently, so note your real volumes on your first brew and enter them under “Fine-tune your system”.

Why Brewfather? Most of our brewers keep their recipes and brew logs in Brewfather or BeerSmith. Set up your system there once with the numbers above, and any recipe you download here imports and scales to it.
