Last night I ordered a drink at one restaurant bar and then at another someone else had the same thing. It was some Bourbon over ice and at the first one the booze was pure monkey juice with an isoamyl acetate aroma which would knock your socks off, at the second it was fine. Not sure what the difference was, I watched them pour the hooch at one restaurant and at the second it was delivered and I missed the pour. Anyway, it got me wondering if it was possible to have bottle variability in something which isn’t single barrel or small batch. My gut says no and what was served at the second place wasn’t what was promised, but I’ll have to do some additional research to be sure. Just seemed odd one bottle would have an ester which was so pronounced and another would be devoid of that same ester. I suppose it could be the ice in the Bourbon, but I doubt that as well.
