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.
Examples:
Kyle's Nut Brown ale had an OG of 1.054 and an FG of 1.015 resulting in 5.3% alcohol by volume.
