I once favored Boissiere for martinis (which are made with gin and vermouth), but I agree that it's not as good in cooking. Because of that and the fact that it's not to be found just anywhere (at least around here), I rarely buy it any more. For both martinis and cooking duty, Noilly Prat is now my vermouth of choice. I used to assume that Gallo vermouth from California, which is very cheap indeed, couldn't possibly be any good. Then a few years ago on one of Julia Childs's television programs she said something about a California vermouth that was just awful, but whose name she would not reveal. Well, she had to be talking about Gallo, so I felt my actually uninformed judgment had been validated. Who would know better than Julia? Then a couple of years ago, Cook's Illustrated did a blind test of vermouths in cooking (I think they might also have tasted the stuff as is), and surprisingly the two winners were Noilly Prat and Gallo, with M & R and Boissiere down at the bottom of list. So one day when I was in an inferior supermarket in rural Virginia needing some vermouth and all they had was Gallo, I bought a bottle. It's very good! A nice clean taste with the appropriate floral notes, no off flavors at all, and it's good for cooking and martinis. And as I say, it's cheap even for vermouth.
