Clement Single Cask (which I was delighted to be introduced to by Sailor22). As the name suggests this is from a single cask that is generally 7 to 9yo which is likely a good deal older than the Clement Select Barrel which is 3+ years old and only 80 proof (the Single Cask is 93.6 proof). The Single Cask was available only outside the US in the past (it comes in the dreaded 500ml) but it has been rumored that it will be brought to the US in limited quantities in a 375ml. I have yet to see it in Atlanta (or anywhere else so far) but I keep banging on people for information about it.
Admittedly the Single Cask is likely to be significantly more costly than the Select Barrel. Then again, as good as the Select Barrel is, I find the Single Cask to be considerably better. I like the 6 and 10yo Grande Reserve too but the Single Cask is still the best to me.
I have since acquired a handful of bottles from overseas but would love to be able to buy it locally so if you see it please let me know! NOLA might be the kind of market where it would show up with its French and Caribbean roots.
