ABV Adjustments
Calculate how much Alcohol is needed to raise the ABV. Spike sparkling water or how does adding Bourbon affect your beer ABV
Example 1. Spike 12 oz. sparkling water to 5% ABV. Add 1.7 oz of 40% Vodka.
Click the Starting Volume box and tab to the next field.
Example 2. Starting volume of your beer is 640 oz. Starting ABV is 7%.
Add 6 oz Bourbon at 40%. Find the new ABV

This calculator can be used to expirement with adjusting a grain to change the gravity of your beer. This could be useful if you need to scale up a recipe based on your efficiency. Based on the values you use, I will display the weight of the grain needed to add or remove to change the gravity. This can also be used to determine how much DME to add to adjust gravity. You can use this tool calculate you efficiency albeit harder as you have to determine your recipe average PPG then add your Original Gravity and adjust your efficiency until you get your grain bill weight. e.g. my 1.044 Blonde with a PPG of 38 and Efficiency of 70% gives me the 9lbs I used.
Enter points to change (1.004 = 4 points. 1.040 to 1.050 is 10 points)
