There is a nice short review of Islay Single Match Scotch Whisky brands over at the NY Times.
The article makes some interesting observations and facts about the seaside Islay. This might be useful to you if you are looking for a last minute gift for a 'peat' lover, or are a wanna be peat lover.
I have had the Lagavulin 16 and Bowmore 12 on the top ten list and enjoyed both. Laphroaig tops the list for value, and appears twice, but I have not had those distills. I have had the Laphroaig Quarter Cask, and wouldn't recommend it for peat noobs, but it is a must try for peat lovers.
