Within the Brew Meister for EasyDens mobile app you are able to choose three different equations to estimate the alcohol by volume (ABV) of your beer.
ABV determination with °Plato:
-
Hubert Hanghofer Formula
ABV = ρ * ABW / 0.7894
Source: Hubert Hanghofer (2010). Gutes Bier selbst brauen (11th ed.). blv. ISBN 978-3-8354-1556-0
ABW = 81.92 * (OG - FG) / (206.65 - 1.0665 * OG)
ρ... density [g/m³] (Density measurement undertaken by EasyDens)
ABV determination with Specific Gravity:
-
Standard Formula
ABV = (OG - FG) * 131

-
Alternate Formula
ABV = (105 / 0.79) * ((OG - FG) / FG)

Please note that Brew Meister for EasyDens uses your temperature corrected results for SG / °Plato for the selected equation.
