I opened a bottle of Bowmore Darkest that I had saved from a few years ago.. It had the FWP taint . I wrote a letter to Bowmore in the US and got this reply.....

"I assume you had opened the bottle of Darkest for the first time just recently. Scotch can change in the bottle after it has been opened due to oxidation, etc. just like any food product can. Spirits generally last longer because of the alcohol content unless you left the cap off. If you opened it for the first time and experienced an unfamiliar odor it may be that you aren't accustomed to single malt scotch or, more likely, you never tasted an Islay malt before. Islay whiskies are known for their peaty, smoky, salty, iodine flavors and aromas. Islay malts are very esoteric and not generally appreciated by the novice scotch consumer. Lagavullin and Laphroaig are other examples of Islay whiskies. Maybe you should try a Highland malt next time. It will certainly be less peaty and may suit you better. Bowmore has won more awards than any other single malt whisky in the world. "
