Reader Evan asks (in a nutshell): Does vermouth go bad?
Grab that bottle of vermouth that’s been sitting open in your liquor cabinet for a year and take a sip. Yeah, it goes bad. Real bad. Vermouth is basically just wine, after all.
But how long does it last after you open it? Conventional wisdom is all over the map, so I put the question to the experts at Noilly Prat. Their answer: After opening a bottle of vermouth it should be stored in the fridge, where it will keep for about three months.
There ya go. Here’s an idea: Replace your vermouth whenever you replace your fridge deodorizers.
