Definition: FG - Final gravity is a measure of the unfermantable substances remaining in beer after fermentation. When FG is mathematically compared to OG, Original Gravity, the exact alcoholic strength can be determined.
Kyle's Nut Brown ale had an OG of 1.054 and an FG of 1.015 resulting in 5.3% alcohol by volume.
