Within the Brew Meister for EasyDens and SmartRef 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 and SmartRef app uses your temperature corrected results for SG / °Plato for the selected equation.
