Whisky Johnnie Walker Blenders Batch Red Rye Finish. Inspired by the bold flavours of American whisky, it was created by a whisky maker’s small team of expert blenders, led by master blender Jim Beveridge. At any one time there are hundreds of ongoing flavour experiments being carried out by the Johnnie Walker blending team in Scotland, and the Red Rye Finish is the first of these batches. It includes malt and grain whiskies aged in first fill bourbon casks and finished in rye casks. It took more than 50 experiments exploring 203 malt and grain whisky samples to hit upon Red Rye Finish and it was created using a blend of just four whiskies, including Cardhu single malt for its vibrant, fresh fruitiness, along with creamy, vanilla grain whisky from Port Dundas.
