How It Works
The Original Gravity (OG) Calculator by Grain Bill uses the formula: OG = 1 + (points / (batch size * 8.345)), where points are calculated as grain weight * grain potential. This formula is based on the standard brewing practice of measuring the potential of grains to contribute to the original gravity of the wort.
How to Use
- Enter the weight of the grains used in the recipe in pounds.
- Enter the potential of the grains in points per pound.
- Enter the batch size in gallons.
- Click the “Calculate” button or press enter in any of the input fields to calculate the Original Gravity (OG).
Common Questions
What is grain potential?
Grain potential is a measure of the amount of fermentable sugars that a grain can contribute to the wort. It is usually expressed in points per pound, and can vary depending on the type of grain and its moisture content.
