Yes. All non-distilled liquor requires refrigeration after it's opened. Vermouth is wine, and wine turns to vinegar if you leave it out. According to the experts at Noilly Pratt, an opened bottle of vermouth will last about 3 months if it's properly refrigerated. Buy the small bottles and keep them in the fridge.

Vermouth, just like Vodka, Gin, Rum, Tequila, Whiskey, or Scotch is a liquor. As long as you leave it in a closed container it will last forever.^ ...the above answer is not quite so, vermouth is a fortified (with alcohol) wine, as such, it lasts a long time. However, at 18% alcohol, it is much lower "octane" than the other mentioned drinks; Vodka, Gin, Rum, Whiskey and Scotch all (usually) have at least 40% alcohol, up to (sometimes) over 75% (151 rum). Vermouth keeps well, and very well if refrigerated.

Vermouth is a wine. Once it is opened it can last for months, but no longer than that. Then the flavour tends to deteriorate, though you can still use it for cooking. The flavour is always best when martini is freshly opened.
