Alcotec 48 turbo

[YHB]

Turbo Yeasts are easy and contain all the nutrients that the yeast need and perhaps more than they need.

You will need to provide the Single Strain Whisky Yeast that you quote with nutrients via a different route. Some of the recipes here such a all bran and cornflakes or UJSSM will contain all the nutrients required, others including sugar washes will need additional nutrients if they are to ferment out completely.

I use Alcotec whisky yeast ferments my washes from around 1080 to close to 1000 approx 12% ish ABV takes about 5 days pretty good results so far

' If you shoot for about half that ABV 10-11% there will be a huge reduction in the off flavours'

Thanks for that informatiom. I am sure that you are correct but could you possibly explain why this would be so. (Excuse me if I'm being dim). Understanding why helps me learn,

Also, to reduce to such an % abv would seem to eliminate the major reason for the use of the yeast, or was this an implied point? A Single Strain Whisky Yeast would produce the %abv that you mention, though probably without the flavour taint.

-----------------------------------

Yeast don't like to be stressed - big swings in temp, getting too hot, pH too low and high alcohol levels will all stress and eventually kill the yeast, when they are stressed they produce compounds that don't taste very nice to us. Keep them happy and they produce cleaner alcohol, then sink to the bottom still alive when they eat all the sugar.

Turbos have nutrients and pH stabilizers so they are a simple solution - I ferment 10Kg of sugar with a single pack, but I'm doing a 50-55L wash so shooting for about 11%.
