Home Brewed Beer Calculators
Home brewing beer calculators to aid in your brewing. These calculators work well with our brew day sheets, or stand alone.
Computes all of the following: ABV, IBU, SRM, OG, FG. Allows scaling by batch size or efficiency, matches recipe to style,
and has many advanced features. Allows saving, sharing, and the ability to 'brew' a recipe.
If you took an original gravity reading (or had estimated OG), and also took a final gravity (FG) reading prior to adding priming
sugar bottling you can find out your batch’s alcohol by volume ABV.
The hotter the wort is, the less accurate your hydrometer reading becomes.
This calculator tells the actual specific gravity no matter what temperature the sample is at, and provides a place for
you to enter your hydrometer's calibration. Hydrometers are typically calibrated to (59F/15C, or 68F/20C).
IBU = international bittering units. This calculator tells you how many IBUs your batch has, given hops additions and wort gravity.
SRM = Standard Reference Measure. Tells how light or dark your home brew will be based on the amount and types of ingredients. Uses Morey's Formula.
Calculates how much you need to dilute or boil down your wort volume to hit a certain gravity. Helps
you hit the correct wort volume and target gravity for your home brewed beer!
Pitch your yeast like the pro's do with this easy to use calculator that supports dry yeast,
liquid yeast, slurry, and starters. Choose your desired pitch rate in million cells / milliliter of wort / ° Plato.
Calculates yeast viability, starter size and how much DME to add to that starter. Supports 3 step-ups, including yeast slants.
Converts refractometer readings taken of wort (Brix WRI) to their actual value in Brix / Plato and Specific Gravity.
Supports alcohol correction of refractometer readings when calculating FG (which requires OG).
All Grain Brewers:
For infusion mashing, use this calculator to find out your strike water temperature and volume.
If you are performing additional rests you can plan them out in advance.
If you are an all grain brewer and want to know your expected original gravity (OG),
expected final gravity (FG), and expected alcohol by volume (ABV), you can plug in the
numbers and get instant results. This calculator is specifically designed to work with our
all grain brew day sheet.
Water chemistry calculator for beer brewers targeting certain mineral levels.
Converts salt additions to teaspoons. Calculates balance of flavor ions and checks for harmful levels.
Computes mash pH using state of the art engine written by Kaiser.
Supports slaked lime, acid additions, multiple water sources.
Reports beer mash extraction efficiency in percentage terms and points per pound per gallon (ppg).
Useful for all grain beer brewers to calculate their actual efficiency at extracting sugars from the grain during the mash.
Finds the amount of boiling water needed to reach a new rest temperature in your mash tun.
For use in the middle of mashing.
If you are an extract brewer and want to know your expected original gravity (OG), expected final gravity (FG),
and expected alcohol by volume (ABV), you can plug in the numbers and get instant results.
This calculator is specifically designed to work with our extract brew day sheet.
Bottling, Priming, and Kegging:
Ever wonder if you have enough bottles to hold your 5 gallon batch? Ever wondered if you have 4 22oz, and 6 half liter bottles,
how many 12oz bottles do you need to cover the rest of the batch? This calculator does the math for you.
Calculates how much priming sugar is needed. Works with table sugar, corn sugar, and DME.
Calculates regulator PSI setting based on desired volumes of CO2 and temperature.
Wine making calculators, not directly related to brewing beer. However there is some overlap between beer brewing and wine making.
These calculators are useful in making grape wines as well as meads and fruit wines.
