Four fields drive every calculation on the page:litres
The volume you expect in the fermenter. Every gravity figure is a
concentration, so this is the single biggest lever on OG.
minutes
default:"60"
Used for hop utilisation, so it feeds IBU directly.
percent
default:"72%"
Your brewhouse efficiency — how much of the theoretical sugar you actually
extract. This describes your system, not the recipe. If imported recipes
consistently read high or low, this is usually why.
all grain | extract | partial mash
The brewing method. Extract recipes do not use efficiency the same way,
because extract yield is not a function of your mash.
Ingredients
Fermentables
Fermentables
Grain, sugar, liquid extract, dry extract, or adjunct. Each carries a weight
in kilograms, a colour in SRM, and an extract yield percentage.Weight and yield determine OG; colour determines SRM. Brewgravity ships presets
for common malts, so picking “Maris Otter” fills in sensible colour and
yield rather than making you look them up.
Hops
Hops
Each addition has an amount in grams, an alpha acid percentage, a time in
minutes, and a use: boil, dry hop, mash, first wort,
whirlpool, or aroma.Only additions that contribute bitterness affect IBU, and their contribution
falls off sharply as time drops — which is exactly why a 5-minute addition
barely moves the number and a 60-minute one dominates it.
Yeast
Yeast
Strain name, type (ale, lager, wheat, wine, champagne), form (liquid, dry,
slant, culture), and expected apparent attenuation.Attenuation is what turns OG into estimated FG, and therefore ABV. If you
know from experience that a strain finishes drier than the lab number, put
your number in — the estimate will follow you rather than the packet.
Other ingredients
Other ingredients
Spices, finings, water agents, herbs, flavourings, and anything else. Each
has a type, a use (boil, mash, primary, secondary, bottling), an amount with
its own unit, and a time.
Mash steps
Mash steps
An ordered schedule of infusion, decoction, or temperature steps, each with
a target temperature and a rest duration. A single 60-minute infusion at
66 °C is a perfectly good schedule; step mashes are there when you want them.
The stats
Stats recalculate on every keystroke — there is nothing to press.Versions
The right-hand panel has two tabs: Stats and History. History lists every saved version of this recipe, newest first, with the kind it came from and the numbers it had at the time. Versions appear two ways:
Editing a recipe never creates a version on its own — the list stays short
enough to be useful.
Click any version to see what has changed since it: the individual edits, and
the effect on OG, FG, ABV, IBU and SRM. Two icons on each row:
Brew this version
Starts a brew session from the version exactly as it was. Your current
recipe is not touched.
Restore into the recipe
Rewrites the recipe back to that version. It lands as a single undo step, so
⌘Z takes it all back.
Saving twice with no changes in between reuses the existing version instead of
adding a duplicate. Restoring re-adds any missing ingredients at the end of
their list — the ingredients match, the ordering may not.
