Bulk Whisky

Whisky is a spirit produced exclusively by distillation at less than 94.8% vol. of a mash made from malted cereals. The final distillate is then matured for at least three years in wooden casks not exceeding 700 litres capacity.

Malt whisky is made from three ingredients: barley, water and yeast. The process can be broken down into five stages:

(1) malting - the barley is germinated to convert the starches into sugar;
(2) mashing - to render soluble as much of the malt as possible;
(3) fermentation - through the addition of yeast;
(4) distillation - a means of separation through vaporisation and then condensation; and
(5) maturation - in oak cask for a minimum of three years.

Grain whisky is made from any cereal grains such as maize or wheat. The processes involved in grain whisky production is very similar to those involved in malt whisky. Both grain and malt whisky are produced from malted cereals. The main difference is that for grain whisky cereals such as wheat or maize are used and not barley. In addition, the type of still used is different. Grain spirit is very pure, matures faster than malt and is less prone to quality variations. Our grain whisky is aged for a minimum of 3 years in order to comply with EC regulations.
