Here are a few of my favorites with little or no peat: anCnoc 12, Arran Bourbon Cask 1996, Auchentoshan Valinch (or Classic), Balblair (several different vintages), Benromach Cask Strength 2001, Bruichladdich The Laddie Ten, Deanston 12, Glenmorangie Astar (not bourbon barrels, but a similar profile from Jack Daniel's barrels), Glenrothes Alba Reserve, Tullibardine 1993
And here are a few peated favorites: Ardbeg 10, Ardmore Traditional Cask, BenRiach 10 Curiositas, Bruichladdich PC 7, Edradour Ballechin # 6, Kilchoman (any of the bourbon cask releases), Laphroaig (many)
Thanks for the suggestions. Many of these were on my list of whiskies to try; however, it can be hard to find out how they are aged. I didn't realize so many were bourbon aged now.
A LOT of Single Malts are bourbon aged. Almost every whisky that isn't Sherry aged is Bourbon Cask aged. So your search for bourbon aged whisky will definitely be fulfilling.
What other bourbon cask aged whiskies are there besides Glenlivet's Nadurra? I enjoyed that one enough to grab another bottle.
