"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.
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

Testing the AlcoDens gauging and blending calculator is risk free. Download and test the free, but fully functional, trial version for 15 runs before you make the decision to buy. After your purchase you are covered by our 30 day money back guarantee. No questions asked. And if AlcoDens is upgraded tomorrow you get that free too. In fact all updates released within 12 months of your purchase are yours for free. No risks, just great software.
AlcoDens is designed to work with mixtures of ethanol and water only, but many products have added sugar as well. The calculation problems caused by the shrinkage or contraction that occurs when water and ethanol are mixed are even worse when sugar is added into the mix. The degree of shrinkage varies with both the alcohol and sugar concentrations, and of course with the temperature.
We are currently developing a new application, called AlcoDens LQ, which will provide several tools similar to those available in AlcoDens but with the added capability of accurately calculating the impact of added sugar. More details of the AlcoDens LQ program, together with examples of the calculators already completed, are available here.
"Hi Harvey, Just tried the freezing point calculator and it's fantastic! I like the other tools you've added too. Many thanks for the update. Kind regards, Pete"

First public release of AlcoDens
"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"

AlcoDens isn't only used in the comfort of the office. Here it is being used right on the distillery floor during blend gauging at Six & Twenty Distillery.
