The Boplaas Whisky is a blended cask-aged grain whisky.  It is made from maize, and distilled to an alcohol content of 93% and then diluted with distilled water to 68% strength. The ageing takes place in American oak barrels for between 54 and 60 months. The spirit is then finished in Boplaas brandy barrels for a short time. The Boplaas single grain whisky is bottled unfiltered.
