A fast fermenting Vodka
For those looking for a fast ferment, a little time spent during the preparation stage pays huge dividends in shortening the time for a ferment.
Here is my routine for a fast Vodka at very low cost wiith no carbon filtering or added clearing compounds.
Ingredients ( for a 23l wash)
250g wheat bran
1 Multivitamin tablet
Pinch Epsom salts
½ tsp DAP Di-Ammonium Phosphate (available at good HBS or dee the discussion for a couple of good mail-order sources)
50g bakers yeast
I source the bran from the local Stockfood Co (5kg bag for $6.50) however most supermarkets will have it as baking bran. This is not the All-Bran breakfast cereal but works out so much less expensive.
In a large pot (5 litre or bigger) bring 2 to 3 litres of water to the boil.
Add the 250g of bran, bring back to the boil then simmer for 30 minutes stirring from time to time
Dissolve the sugar in warm water and add to the fermenter wiith cool water to bring quantity up to 20 litres.
Add the crushed MV tab, Epsom salts and DAP.
Once the bran has simmered for 30 mins, add it to the fermenter.
I then adjust the pH to around 5 wiith the citric acid (usually takes about ½ a tsp.)
Rehydrate the yeast in 100ml water and add to the mix. (A good guide to rehydrating is on the site) Making sure the start temp is below 30C
Stir well (I use a stick blender to thoroughly aerate it.)
Leave plenty of headroom as this takes off like a rocket. I use a 30l fermenter
Do NOT seal for at least 24 hours as a thick foamy cap will form within an hour. I put it under an airlock only after 36 hrs so I can monitor progress.
This produces a fast ferment ( normally dry to .990 within 3 to 4 days).
Rack off and allow to stand for a couple of days to clear before distilling.
I find this has a nice slightly wheaty taste and is much nicer than the TPW.
