I bought a 200 ml to top up my current JD vatting and was surprised how good it was. Soft and elegant, and it reminded me of nothing so much as the original Michter's (despite the low rye in the Jack). It had zero banana or other fruit but a complex slightly smoky sweetness.
I bought a couple more from the same shelf a few days later and they taste the same.
Jack is getting better and better and it's not my imagination. For once I thought it was worth the money - and more.
