If I am out and see an attractive bottle (Gray Goose has a beautiful bottle), I will ask for that and so far have none of the problems that I had with Fleischmans, and other "bar rail" vodkas I had before.
As I said, I never knew when I would get the headaches, but they were crushing, so I assume it was from certain batches as opposed to brands, maybe some impurities that wouldn't be filtered out in cheap vodkas. Or who knows, maybe it was all in my head.
I would be interested in trying this new brand, because there is also a subtle taste difference in vodkas, I notice that the higher quality, the smoother the taste (not unlike many liquors).
(Ug I refuse to drink Grey Goose, 1 its french, 2 its french vodka which they pitch as the world's greatest. If the french are great at anything its wine and whine, not vodka)
A lot of vodka like Fleischmans are made in NJ... that's enough to scare you right there.
