Free calculators for home distilling, wine and liqueurs
We have gathered in one place all the calculations you need when working with a still, fermenter and liqueur kit. The calculators work live – just enter your data and the result appears instantly, on your phone too.
Alcohol strength, dilution and blending calculations are based on the international density formula for water–ethanol mixtures (OIML R22), so they include volume contraction. Blg, SG and Oechsle conversions use formulas from brewing and winemaking.
From calculation to shopping – no guesswork
The column packing calculator converts the result straight into packs of prismatic springs and stainless scrubbers that you can add to the cart with one click. Under each calculator you will also find parts and accessories for that stage of the work: heaters, power controllers, condensers, thermometers, alcoholmeters and hydrometers.
Who are the calculators for?
For beginners building their first still who want to match the column, heater and condenser, and for experienced distillers who want to quickly work out dilution water, wash yield or the cost of a run. Each calculator explains how it works and answers the most common questions.
Frequently asked questions
Are the calculators free?
Yes, all calculators are free and require no registration. Your browser remembers the data you entered last.
Can I send someone my result?
Yes. The “Copy link with result” button creates an address with your data – when opened, the calculator shows the same result.
How accurate are the calculations?
Alcohol dilution and blending are calculated from OIML density tables (accuracy better than 0.1 percentage point). Equipment values (column flooding power, packing density) are approximate because they depend on the specific design.
