I've had a bottle of this on my butcher's block for at least 10 years now. It's been opened for that long as well. It's maybe one sixth full now. I have a measure every couple or six months.

Just in the past few months it has started significantly changing and for the better. I used to get what I was supposed to get, pears and oak. Simple and what you'd expect. Lately it's getting lemony and herbal, tyme and rosemary. I really like it a lot now that it's almost gone.

Has anyone else had a bottle around like this that has significantly changed on them or am I the only nitwit that has an bottle lying around open for this long?
