Raw Materials

Scotch Whisky production, as with other distilled beverage manufacture, is dependent on the quality of its raw materials (malted barley, cereal, yeast and water). The challenge faced at the Institute is how to maintain and improve spirit quality whilst ensuring efficiency. Scientific research, a practical understanding of the manufacturing process and close ties with related industries, such as maltsters and plant breeders, help us meet this challenge.

Our research into raw materials at the Institute is targeted at three fundamental areas:

how the potential of cereal varieties for use in the distilling industry can be assessed and improved

how cereal starch is broken down to give fermentable sugars which yeast can convert to alcohol – the alcohol yield being the most significant efficiency index in the industry

how to minimise production problems caused by the gum-like polymers contained in cereals
