Whisky Sheep Dip Islay Blended Malt. A variation of the wonderful Sheep Dip Blended Malt Scotch Whisky, made with malt whiskies from the island of Islay. Plenty of classic Islay character runs through its core, and it's still adorned with the picture of a sheep on the label, so all's good here! The name Sheep Dip comes from the olden days when people in the West Country used to make their own whisky and hide it in barrels marked "SD" to avoid paying taxes on it.
