Millstone Whisky is double distilled in handcrafted copper pot stills. The small stills have an extraordinary large copper surface if you compare them to the large stills used elsewhere. The extra contact between the alcohol vapors and the copper helps to eliminate any unwanted substances and also stimulates the formation of the complex and fruity esters. The small stills thus produce a very delicate and fruity new spirit.After the careful distillation the whisky is aged in small barrels. Millstone use new barrels of American white oak as well as barrels that have previously held Bourbon and Olorosso Sherry. Because they use new or barrels that have been used only 1 time and we store the barrels in a warm and dry warehouse the whisky ages rather quickly. The downside is that the evaporation losses are rather high.
