Big Belvedere fan. Makes a great martini. I have to say however, that Grey Goose is awesome.
The french also have a Citidel Gin. Very tastey.
This French vodka is practically non-existent on the Polish market, has no tradition at all because it was invented in 1997.
Yech. I have yet to taste a French Gin that has a particularly good flavor in either dry or botanical styles. The neutral spirit is usually of good quality in French gin, but the flavor is typically off and of mediocre character.
Depending on your particular style preferences, high-end UK and Dutch gins pretty much lock up the market in the quality department. But if the French come out with something new in gin, I will always buy a bottle to check it out.
