Still Spirits Turbo Yeast Classic 8 (48 hour) is the best all rounder Turbo Yeast, performing excellently under most conditions. Use with 8 kg of sugar for high ABV, or 6 kg of sugar for fast fermenting. Classic has been further improved with the inclusion of new mineral absorbents, further improving distillate quality. We recommend you use Turbo Carbon as it will significantly improve the performance of Classic 8 Turbo.
