Looking for advice, light & subtle non-peated whisky

So a lightweight Bourbon matured whisky

First thing that comes to mind is Amrut single malt, bottled at 46%. A little lighter and less intense than the Amrut cask strength, but nonetheless excellent. Along those lines is the Amrut unpeated CS, and if you can get it, a single cask (bourbon, of course) bottling.

If you want to stray from the single malt realm (you did mention your flexibility), Highwood 90/20, Wiser's Last Barrels, Forty Creek Confederation Oak are all good prospects.

Redbreast 12 YO CS is apparently a mix of bourbon and sherry but I would suggest it is very different from any "sherry monster" and good in its own right.

@Rovaben, try Hazelburn malt, G & M Glenallachie 14yo malt, Bernheim's Original Wheat Whiskey, or Van Winkle 12 yo Special Reserve bourbon.

In no partcular order...

Single Malts: Dalwhinnie 15, Cardhu 12, Glenkinchie 12, Glenlivet 12, Glenlivet Founders Reserve, Glenfiddich 12, Auchentoshan American Oak, Glenmorangie 10, Macallan Fine Oak 10, Aultmore 12, Scapa 16, Scapa Skiren

Blended Whisky: Famous Grouse, Compass Box Great King Street, Compass Box Asyla, Three Ships 5 YO

@tfahey1298 gave some of the answers I would have given. I would especially highlight Glenkinchie 12, Dalwhinnie 15, and Aultmore 12. You've probably already tried Glenmorangie 10 and Glenfiddich 12 anyway. I'd add also Arran 10 as a good alternative.

Add Black & White Blended Scotch and Compass Box Oak Cross blended malt to the list. I like Clontarf Single Malt (Bushmills) very much too, but that one seems to be not too easy to find. Clontarf is the simplest malt I have ever tasted. Barley, without peat or wine, and just the faintest hint of vanilla from oak, and that only after the bottle has been long opened.

Wow! Thanks for the quick replies all!

On to some further research before I decide what to buy.

Midleton Very Rare might be a good choice.It is Irish. If you have deep pockets, it is really worth a try. It is one of the first whiskeys I have tasted and it is very delicate.

Good call @Nozinan, the Amrut is strictly Bourbon cask right? And a good one at that..

@Alexsweden Yes, The Amrut single malt is, I believe, essentially bourbon cask.

the old glenlivet 12 (not the excellence)and arran 10 are both good. i didn't really care for the singleton of glendullan 15 so i'd avoid that one.

Hazelburn, An Cnoc and Glenlivet comes to mind. Start from the standard and readily expressions: 12 Year Olds and work your way up would be my recommendation.

Tomintoul 14yr old

Clynelish 14yr old, Glencadam 10yr old.

For scotch I'd pick the unique Scapa 16 (this might not be available, but there is Scapa Orcadian). It is distilled in Orkney but is non peated.

For bourbon i'd try Jefferson's Old Small Batch, which offers a very light and smooth character compared to other options.
