Fermentation Calculator

Original Gravity (OG) is measured before your wort begins to ferment. Final Gravity (FG) is measured once the fermentation process has ceased. Run your OG & FG hydrometer readings through the 'Gravity Corrector' before entering them below, if you haven't done so...

Refractometer Calculator

Convert a temperature-corrected refractometer reading from Brix/Plato to specific gravity. A standard wort calibration factor of 1.04 is used to correct for non-sugar components in the wort.

Hydrometer Gravity Calculator

Hydrometers are typically calibrated at a reference temperature of 60°F. If your solution is at a temperature other than 60°F, you must correct your gravity readings. Enter the temperature of your sample along with the specific gravity reading in the fields below.

Yeast Pitching Rate Calculator

To ensure that you achieve a complete, vigorous, and fast fermentation, it is often necessary to make a yeast starter. Prepare the starter 1-2 days before your brew day. White Labs vials and Wylabs XL Smack Packs contain an average of 100 billion pitchable yet cells per container.

Infusion Mash Calculator

Calculate the strike water temperature for your initial infusion, and up to 2 additional infusions depending on your step mash schedule. To remove additional infusions, set the 'Target Rest Temp' to 0. Preheat your mash tun!
