The Glen Spey distillery is a single malt Scotch whisky distillery in Rothes, Aberlour, Banffshire at the centre of the Speyside whisky producing area of Scotland.
Glen Spey (along with Glenlossie and Strathmill) continues to use ‘purifiers’. Purifiers act as small condensers, returning a proportion of the alcohol vapours back to the pot to be re-distilled. So, this would increase the amount of ‘reflux’ within the pot stills. This results in a lighter spirit.
