ABV Calculator
Calculate the approximate alcohol content and apparent attenuation of your beer using the Original Gravity and Final Gravity.
OG is the specific gravity measured before fermentation. FG is the specific gravity measured after fermentation.
You can enter gravity as either 1.055 or 1055.
Estimated Alcohol by Volume

Apparent Attenuation: 0.0%

IBU Calculator
Estimate the bitterness of your beer using the Tinseth method. Add each hop addition separately to calculate the total IBU.
Hop Additions
Alpha Acid % can be found on your hop package.
Enter each boil hop addition separately.
Example: Cascade 25 g · 7% AA · 60 min.
Whirlpool and dry hop bitterness is more difficult to predict, so this calculator is primarily intended for traditional boil additions.

Hydrometer Correction Calculator
Correct a hydrometer gravity reading when your wort or beer is measured at a temperature different from the hydrometer's calibration temperature.
You can enter either 1.050 or 1050.
Temperature of the wort or beer when the reading was taken.
Check your hydrometer scale or instructions if unsure.
Hydrometers are calibrated to give an accurate reading at a
specific temperature, commonly 20 °C.
If the sample is warmer or colder than the calibration temperature, the density of the liquid changes and the observed gravity reading should be corrected.
For the most accurate brewing measurements, allow the sample to cool close to the hydrometer's calibration temperature whenever practical.

Temperature correction is an estimate. Accuracy decreases as the
sample temperature moves farther from the hydrometer calibration
temperature.
Refractometer Calculator
Convert Brix to Specific Gravity or correct refractometer readings after fermentation has started.
Brix to Specific Gravity
Enter your Brix reading.
Fermentation Correction
Use this calculator when fermentation has already started.
Enter the original and current Brix readings.

Brewhouse Efficiency Calculator
Calculate how efficiently your brewing system converts the potential extract from your fermentables into wort collected in the fermenter.
Fermentables
Enter the amount of wort that actually reached your fermenter, not the pre-boil volume.
The calculator compares the gravity points collected in the fermenter with the theoretical extract potential of your fermentables.
The listed malt potentials are typical reference values. Actual extract potential varies by maltster and product. Use Custom Potential when you have the exact specification from the malt analysis sheet.

utilities, packaging and equipment — and see exactly
how much your beer costs per liter and per bottle.

Carbonation, purging and serving allocation.
Fruit, spices, filters or any other expense.
How it works: enter the package size, package price and the amount actually
used in your recipe. The calculator automatically charges only
the portion consumed in this batch.
Example: a 100 g hop package costs €8 and you use 65 g. The hop cost for the batch is automatically calculated as €5.20.
Currency conversion is not performed. All prices should be entered in the currency selected above.
