Beer Styles – Original Gravity and Final Gravity ChartWednesday, February 4th, 2009
Beer comes in a wide range of malt/hop flavor balance and alcohol level. This chart shows the BJCP beer styles and their original gravity and final gravity in bar graph format.
Original gravity (OG) measures how much sugar is present in the wort before it is fermented. The final gravity (FG) is how much sugar is left over when fermentation is done. For a beer to fit into a certain style, each of these numbers must be within the specified range as the chart depicts.
A lower final gravity indicates a dry or crisp flavor, while a higher final gravity indicates a sweet or malty flavor.
The size of the gap between OG and FG can be used to calculate how much alcohol the beer contains.
Data for this chart comes from the the Beer Judge Certification Program (BJCP).
