I get a lot of questions about how to dilute limoncello to a certain proof, or alcohol percentage. So I created this simple calculator to help you reach the proper strength. The calculator labels say ML but it works the same regardless of the measurement used. So if you enter your quantities in liters, the answer will be in liters as well. This calculator is useful for dilution of any homemade liqueur, not just limoncello.
Enter Quantity of Liquor (ml)
Enter Alcohol as % of Liquor (Proof divided by 2)
Enter Desired Alcohol % of Final Product
Total Simple Syrup Required (ml)
