"Harvey: just a note to tell you how much I love Alcodens. Worked perfectly "out of the box" and has become one of the most used and useful tools at my distillery. Thanks for making such a great product! We'd be sunk without it! Regards, David"

AlcoDens is a collection of 6 powerful and flexible calculators designed for distillers, blenders and bottlers of potable alcohol (ethanol). These programs replace the manual calculations that are usually done in conjunction with the TTB Tables, the Practical Alcohol Tables and Ethanol Density Tables. They will give you quick, easy and accurate determinations of your alcohol stocks and calculations of your alcohol blending, proofing, dilution and fortification ratios, plus a few extra calculations that go beyond what the tables can do for you.
Where applicable, the AlcoDens calculators will allow you to specify the strength (concentration) of the alcohol blend using Alcohol Proof, ABV (Volume %), Mass %, Ethanol Density, or Molar %. The data covers temperatures from -20°C to 100°C (-4°F to 212°F) and concentrations from 0 to 100% (0 to 200 Proof). All ethanol density and strength data values between -20°C and 40°C are compliant with the International Alcoholometric Tables (OIML), but can also be expressed on an "in air" basis to make AlcoDens compatible with the TTB Tables used in the USA.
In addition to this flexibility in specifying the alcohol blend strength, AlcoDens has a very wide range of units built in for specifying or calculating the temperatures, masses, volumes and densities.
AlcoDens is designed for mixtures of alcohol and water only. If you need to do calculations for liqueurs that also contain sugar please see AlcoDens LQ.
The six calculators are:
All of the AlcoDens calculators have built-in context sensitive help available at the press of a button. Or if you need more help than that you are welcome to email us for the support you need.
"I have been using version v2.3 regularly for the last couple of months since its release and I find it very quick and easy to do almost any imaginable distillery calculation. The author has been very helpful when I have had queries, and included some extra features I suggested after using v2.2 initially." Peter Bignell

"Harvey, ... the end of the process always comes back neatly to the values we need after applying the recommended quantities that AlcoDens comes up with. It has become an integral and indispensable part of our wine batch management. We use it as the basis of all our fortified batches. So thanks a lot, it's a great product! Regards, David"
