I'll go the Sherry. Especially if I can get it at the same price as I once did in a pub in the Scottish Highlands.
The young lass behind the bar couldn't find the Talisker 20 on the till (a computer-controlled till with touch-screen), so she gave it to me for the same price as the only Talisker she could find, Talisker 10... I quickly ordered a double.
I love when that happens--had a Glenfiddich 30 for the price of an 18 once. Not sure it was worth it, anyway, but at least I got to try it.
Lugy, sherry and peat can be a marvelous combination. If I were the one looking at those two bottles, I'd probably think about it for ten minutes and buy them both.
