Whisky Words: Yeast

Vic Cameron, one of our whisky lecturers says: “Yeast is one of the three raw materials used to make single malt Scotch whisky. The others, of course, are malted barley and water. Yeast is used in fermentation and it's a unicellular organism. We add it to the wort that we get from mashing in washbacks and that's what metabolises the sugar to give us the alcohol.”
