})();How It Works
The Bitterness Ratio (BU:GU) Calculator uses the following formula: BU:GU Ratio = IBU / GU, where GU is the Gravity Units, which is calculated as the difference between the Original Gravity (OG) and the Final Gravity (FG) multiplied by 131.25, which gives the Alcohol By Volume (ABV). This formula is used to determine the balance between the bitterness and the gravity of a beer.
How to Use
- Enter the Original Gravity (OG) of your beer
- Enter the Final Gravity (FG) of your beer
- Enter the IBU (International Bitterness Units) of your beer
- Click the “Calculate” button to calculate the BU:GU Ratio
Common Questions
What is the ideal BU:GU Ratio?
The ideal BU:GU Ratio varies depending on the style of beer, but a general rule of thumb is that a ratio between 0.5 and 1.0 is considered balanced.
