Yep you are right, the first Black Bottle (in a green bottle) was more Islay biased than the current bottling. Every-time I find an original bottling I snap it up, really nice easy drinking daily dram.
Ordered this along with the two gins as part of their Black Friday deal, should be here today to tomorrow. Deal was so good for the two gins that the whisky is just a bonus. Will pour a dram when it arrives and report back
