Whisky Johnnie Walker Sweet Peat. Too often pitched as opposite extremes on the Scotch whisky flavour spectrum, peat smoke and sweetness can actually work together remarkably well. This fact is exemplified in Sweet Peat from Johnnie Walker, which blends powerful peat and citrus flavours with sweet Speyside character and a luscious sherried note. The result is a flavour profile full of rich caramel and vanilla flavours, a light spiciness and wisps of warming wood smoke.
