Distilling & equipment

Column packing calculator – prismatic springs How many litres of prismatic springs your column needs, split into copper and stainless – with the number of packs ready for the cart. Calculate → Stainless and copper scrubber calculator for columns How many stainless or copper scrubbers (20, 40, 60, 100 g) you need to pack your column – with the number of pieces ready for the cart. Calculate → Heater power and column working power calculator Heater power from voltage and resistance (P = U²/R), current, fuse selection and safe power for your column diameter. Calculate → Wash heat-up time calculator How many minutes it takes to bring the boiler to a boil at a given heater power – and how much electricity it uses. Calculate → Condenser water flow calculator How many litres of water per minute the condenser needs at a given heating power – and how much water the whole run uses. Calculate → Coil (spiral) calculator – tube length and heat transfer surface How much tube a coil needs, how many turns it has, its heat transfer surface and cooling power – for single and double coils. Calculate → Boiler capacity and charge calculator Boiler/keg capacity from its dimensions, a safe charge (no boil-over into the column) and how much sugar fits in the wash. Calculate → Distillation cost – calculator What electricity, sugar and yeast cost – and the price of 1 litre or a 0.5 l bottle of the finished product. Calculate →

Alcohol – strength & dilution

Alcohol dilution calculator (with contraction) How much water to add to spirit or distillate to get 40% – precisely, taking volume contraction into account. Calculate → Calculator for blending two spirits What strength and volume you get by mixing two distillates of different strength (e.g. several hearts fractions). Calculate → Ethanol boiling point vs. pressure Boiling point of ethanol and water at current pressure or altitude – useful for reading your thermometer. Calculate → Alcoholmeter temperature correction The true alcohol strength when you measured at a temperature other than 20°C. Calculate → Liqueur calculator The strength of your liqueur after adding juice, syrup, sugar or honey – and how much spirit to add to reach the target strength. Calculate →

Wash, wine & beer

How much alcohol from 1 kg of sugar? Sugar wash calculator How much pure alcohol and 40%/60%/96% distillate you get from sugar and how much water a wash of your chosen Brix needs. Calculate → Blg / Brix / Plato / SG / Oechsle / Baumé / KMW converter Enter a value on any hydrometer scale – the rest is converted automatically. Calculate → Alcohol content of wine, beer and wash The ABV of your wine, beer or wash based on hydrometer readings before and after fermentation. Calculate → Wine calculator – sugar and metabisulphite How much sugar to add to the must to reach your target strength, and how much potassium metabisulphite for a given SO₂ dose. Calculate →

Workshop & materials

Steel weight calculator – sheets, bars, tubes and profiles (m ↔ kg) How much a metre of tube, bar, angle, channel, tee or hollow section and a sheet weigh – and how many metres a given number of kilograms is. Steel, stainless, aluminium, copper, brass. Calculate → mm to inches and inches to mm – standard and pipe inches Convert millimetres to inches (with fractions, e.g. 1 1/4") and back, and check how many millimetres a pipe and thread are in pipe inches (1/2", 3/4", 1", 2"…). Calculate → Tap drill and die rod size calculator – metric, BSP (G), UNC, UNF, BSW Which drill to use for a tapped hole and what rod diameter to prepare for a die – for metric, BSP (G) pipe and UNC, UNF, Whitworth inch threads. Calculate →

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.
