This app calculates the amount of water to dilute a known volume and percentage of alcohol. The user enters the number of liters or gallons of the sample to be diluted, the known alcohol percentage of the sample, and the desired final alcohol percentage. The app will then calculate the amount of water to add in gallons or liters. Calculations are based on density values at 20 degrees Celsius from the International Alcoholometric Tables - OIML. Results are approximate values only, but are significantly more accurate than standard dilutions equations. Care should be taken to prevent over-dilution of your spirits. ## Key features - Calculate water needed for dilution - Input volume in liters or gallons - Enter known and desired alcohol percentages - Uses International Alcoholometric Tables - Accurate dilution calculations ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/spiritulator/id482443691/reviews.md ### 1/5 — Useless *2020-12-01* Not user friendly **Developer response:** Please specify why it’s useless and not user friendly. All others have rated it 5 stars. Do you have experience diluting distilled spirits? Please let me know how to improve. Thanks. ### 5/5 — Work like a charm *2016-07-04* Colors a bit trippy, but it does what it supposed to 👍😉 ### 5/5 — Now accurate for small volumes too! *2013-05-11* Thanks for the update!! The additional 2 decimals make this app perfect for the brew hobbyist. Thanks for listening and responding with this update !!! Happy to change my rating to 5 stars!!! Previously: App rounds to only one decimal point, fine if you are dealing with hundreds of gallons or liters, but not accurate enough when working with volumes of less than 1 liter or gallon. Example: this app says to add 400 ml to 700 ml of 76% ABV to create a 50% solution. That would actually yield a 47.8% solution. Correct answer would be to add 364 ml. An easy fix would be to change the App calculation to 3 decimal points. ### 5/5 — Just what I needed *2013-05-02* It's a simple little utility that will certainly make your life easier when you're cutting your distillate. ### 5/5 — Great App *2011-11-29* Very handy when you need to dilute your spirits. I always had to do it by hand or use an Internet calculator. A lot easier and more convenient now. Thanks! ## Frequently asked questions about Spiritulator ### What is Spiritulator used for?
