Wm Teacher & Sons was established in 1830, when a Victorian grocer named William Teacher began selling whisky in Glasgow, Scotland. Teacher's became an immensely successful brand as the company hedged its sales during the First World War by distributing to its customers ration coupons, which entitled them to only five glasses of Teacher’s per week. When the war was over, business resumed, and the company was able to fulfill growing demand from its ample supply. Jim Murray, the world’s leading whisky authority, states in his Whisky Bible 2004: "This is a whisky of spellbinding complexity and of a style that is an umbilical cord to our blending forefathers."
