Here is a simple calculator so you can quickly calculate the ABV% of your wash after fermentation.

• Enter the original gravity (OG) value in the "Original Gravity (OG)" field. This is a measure of the density of the wash (unfermented wash) before fermentation. It is typically expressed in specific gravity units.
• Enter the final gravity (FG) value in the "Final Gravity (FG)" field. This is a measure of the density of the wash after fermentation. It is also typically expressed in specific gravity units.
• Click the "Calculate ABV" button.  The result will be displayed on the page. It will show the calculated ABV as a percentage.
