Well now, I just happen to have a bottle of Cragganmore CS lying around--bought it a year and a half ago for $105. I have opened it this very evening, just for you! The sacrifices we make here at Tattie Heid Central, just to help out our fellow forumites! My only regret is that there isn't a real feinschmecker around to give you proper notes. I will do the best I can.
I had a wee spot earlier, just before dinner, to warm up. After dinner, I finished off the end of a Cragganmore 12 mini, just for comparison. Then I poured a small amount of the CS and watered it, in an attempt to tease out some aromas. Honestly, I have no nose. ("How does he smell?" "Terrible!" ...Ahem.

) I want to say orange blossoms, although I've never actually smelled orange blossoms; but it's pleasantly and sweetly floral and orangey. Tasting the watered dram, I get burnt bitter orange. Back to the full strength. I usually enjoy cask strength whiskies without trouble, but I've recently had ten days off from dramming, and the spirit is a bit much for me at the moment. Again, orangey, not unlike a Balvenie, but drier, and with what seems like a peaty buzz on the middle of the tongue. Not an enormously long finish, but I don't feel cheated. It's not far different from the 12, but more intense in every way. The one thing I'm missing here is the oily mouthfeel I get from a lot of cask-strengths; I wonder if this has been chill-filtered. Now I'm really going to sacrifice--I'll pour a bit more and water it, to see if it clouds. Results inconclusive...too many greasy fingerprints on the glass! Doesn't seem to, though, and I've watered it pretty far. Seems a shame to chillfilter a cask-strength like this, if indeed they did (I won't claim to have found out). But I will say the more I sip, the more I like--it's a very tasty dram. If you're a fan of Cragganmore, I think this will be worth it. $100 worth? As I've said many times, it depends as much on what you think of $100 as on what you think of the whisky. I don't spend $100 too often, but I think I will enjoy this bottle, and furthermore I think I will get more out of it as it goes along.
I hope you will get some corroboration from a more sophisticated palate than mine, but there it is, for what it's worth.
