Fellow solo cocktail enjoyers... How long are you really using vermouth after it's opened?
My understanding is the guideline is it keeps 2-3 weeks in the fridge after open. But, I'm literally never finishing a vermouth that fast at home, predominantly mixing for myself. It takes 4-6 weeks, occasionally even 8.... And call me a Philistine... I'm not sure I have ever noticed it 'spoiling'. Am I alone here? Are you all really tossing your vermouth after 2-3 weeks in the fridge?
