A non-age-statement addition to William Grant & Sons growing collection of single grain Scotch whiskies comes in the shape on The Girvan Patent Still No. 4 Apps, which takes its name from the distillery term for ‘Apparatus’. No. 4 Apps has been in use at the Girvan distillery in Ayrshire since 1992. The single grain whisky itself spends its maturation in American oak barrels.
