Old Ballantruan is made in the Tomintoul Distillery within part of the most famous Scotch whisky producing region, “Speyside Glenlivet” using peated malt barley. It's unusual to find a heavily peated malt whisky from Speyside. The Old Ballantruan whiskies contain the smoky phenolic notes that are associated with Islay malts while in the background are sweet notes that characterise the Speyside region.
Old Ballantruan is made using heavily-peated malt barley with a total phenol content of 55 ppm (parts per million). This sits at about the same level as some of the peatiest Islay malts, whereas the most delicately peated malts may have a ppm content of as low as 2 or 3.
