Last night I was enjoying a pour of BT with a bit more water than I usually do. A new taste came rushing to me... COCONUT. I've never tasted that before, and it wasn't fleeting... the experience was reproduceable.
This got me to thinking... we all know of the familiar bourbon flavours (vanilla, oak, citrus, smoke, leather, etc.) but I'd be interested in hearing some of the unusual flavours that you've encountered while enjoying your favourite pour. I'll start with a couple of my experiences:
Buffalo Trace (mixed 4 parts BT with 1 part distilled water) = Coconut.
Wathens (mixed with just a splash of water) = Chocolate
