Wineo's plain ol' sugar wash

A neutral sugar wash “without a bunch of extra stuff in it to cause flavours”. Wineo's answer is simple: use plenty of yeast and only the minimum of nutrients. The result is clean enough to make a neutral spirit even in a pot still.

About this recipe

wineo set out to make the plainest possible sugar wash for neutral spirit. Many sugar-wash recipes add tomato paste, cereals or a cocktail of nutrients; each can leave its own flavour. wineo's insight was that a generous amount of yeast does most of the work itself, so only the essentials go in: a little acid, nitrogen (DAP), calcium (gypsum) and magnesium (Epsom salts).

He pot-stills it and finds it very neutral and very clean - run through a reflux still, cleaner still. His advice to newcomers using turbo yeasts: try this, and leave turbos and carbon filtering behind.

Volumes are typical for the still chosen. Make the cuts by smell and taste, never by volume alone - the guide to making the cuts shows how.

Estimates for planning, assuming a healthy fermentation. Your settings are remembered on this device.

Method

  1. Dissolve the sugar. Dissolve the sugar in hot water and stir until it has dissolved completely.
  2. Add the nutrients. Add the DAP, gypsum, citric acid and Epsom salts, and stir until they've all dissolved.
  3. Make up the volume. Pour into the fermenter and add enough cool water to make the full batch. The starting gravity should be 1.070–1.080; for best results, don't go above 1.080.
  4. Pitch the yeast. Once the temperature is at or below 35 °C (95 °F), sprinkle the yeast on top.
  5. Stir it in. After 15–20 minutes, give it a good stir to mix things up and work some air in. Cover with a cloth or fit an airlock.
  6. Let it ferment out. Depending on the temperature, it works off in one to two weeks. Don't rush it: let it ferment to dryness.
  7. Let it clear. Give it another week to clear before running it.

Fermentation

A glass demijohn of nearly water-clear sugar wash with a column of fine bubbles rising through it, beside bowls of sugar, nutrient crystals and yeast.
Wineo's wash ferments clean and nearly clear: plenty of yeast, and only as much nutrient as it needs.

The large amount of yeast gives a strong start, and patience gives a clean finish. Letting the wash ferment fully dry and then clear for a week is part of the recipe, not an optional extra: it keeps yeast and its by-products out of the boiler.

Distilling

Pot-stilled, it gives a clean neutral; refluxed, a cleaner one. Discard the foreshots, and cut tightly for neutral spirit - see making the cuts.

Fermenting a wash is legal in many places; distilling it often is not. Distil only where it is legal to do so, and check your local licensing first.

Troubleshooting

The starting gravity is low.

Add a little more dissolved sugar, towards 1.070 - but no higher than 1.080.

It's still cloudy after fermenting.

Give it the full extra week. A cool spot helps the yeast settle.
