Glen Spey distillery was built in 1878 by James Stuart & Co. under the name ‘Mill of Rothes’. The distillery actually started its life as an oatmeal mill. The exterior of the distillery is still pleasingly Victorian with solid, weathered stone buildings. Much of the interior, too, is in period. There are two pairs of stills, the second pair being added in 1970 during rebuilding of the distillery. Water is taken from the Doonie Burn. The two spirit stills both have so-called ‘purifiers’. Purifiers act as small condensers, returning a proportion of the alcohol vapours back to the pot to be re-distilled. These purifiers are said to produce a lighter, more delicate malt whisky.
