OK, going out on a limb and perhaps exposing a bit of weirdness here - thank all the powers that be I took Linn's advice and put on extra pants....

Does anyone find the taste of bourbon to change throughout the course of a single bottle? For example, last night, I decided to revisit my bottle of Woodford Reserve, which to date I had not enjoyed. The first three glassses I had from this bottle lacked any trace of sweetness, and were rather medicinal with a touch of sawdust. The glass I had last night was nothing short of splendid. Sweet, full, robust, tingly, and not the slightest bit medicinal. I've had a couple others that I didn't like the first glass from the bottle, and then it gets better - including bourbons I generally like. The first glass from my current bottle of Old Whiskey River, for example, was flat, dry, and awful. Thought I'd gotten a bad bottle...then it's been fine ever since.

Am I having bourbon hallucinations, or has anyone else experienced this type of thing?
