Laphroaig is an institution on Islay. As such, they’ve had time to experiment. Some whiskys get additional flavoring from being partially or wholly aged in a variety of barrels (ex-bourbon, ex-sherry, ex-etc.). The folks at Laphroaig have doubled, nay, tripled down on that area of the distillation process with this Triple Wood offering. The first is ex-bourbon American oak, the second is quarter casks (smaller cask means more of the whisky is in contact with the wood and thus takes on more flavoring), and the third is ex-Oloroso sherry European oak.
