The Alcotec 48 turbo yeast is a “dual recipe” yeast. You can choose whether to produce moderate alcohol (14%) in 48 hours, or high alcohol (20%) in 5 days simply by adding different amounts of sugar. The standard dose of 6 kgs of plain sugar into 25 litres total will give you the 14% recipe. If you instead go for 8 kgs of sugar the turbo yeast will automatically go for 20% in 5 days.
This turbo yeast is also very tolerant to high temperatures. The optimum is still ambient (and liquid) temperature around 25 C, but it is no disaster if the ambient temperature shoots a bit over 30 C.
