I've noticed recently that a few bourbons I've had before taste different to me now after buying new bottles of them.
Eagle Rare SB 10 Year has been my long running favorite, but the most recent bottle I bought was good...not excellent like the previous few bottles I've gone through. In this case, I know there will be some variability among bottlings of a single barrel product, so it didn't come as such of a shock, but it is still a little disappointing to have a bottle that just doesn't seem to live up to the others I've had.
I had a similar experience with a non-single barrel product (at least i think so - there is no mention on the bottle), Buffalo Trace. There first bottle I tried about 8 months ago seemed must less smokey than the newest bottle I got. The new bottle is actually so smokey/ashy to me that I don't really care for it, but I remember liking the previous bottle. Have my tastes changed that much in 8 months? Or are the bottle bottles really that much different?
The other whiskey I've run into this with really screams product inconsistency to me and no just variability. I really enjoy the first 2 bottles of Michter's Unblended American Whiskey that I had. Lots of vanilla and caramel flavor and a very low amount of wood - a nice change of pace from bourbon. To me, the flavors tasted "natural", and nothing was cloying to me. The newest bottle I bought tastes very artificial in comparison, like they've been adding flavoring all along and for some reason in this batch, it just didnt mingle well with the whiskey. Since the issue with Michter's is that no one seems to know who distill's thier stuff, I have my suspicions about something being added to this particular whiskey.
Have any of you run into similar situations with a certain whiskey you like - you get a bottle that just doesn't match up to the last few you had?
