I love beer but recently I have been drinking a lot of Old Fashions (thanks Don). I used to drink Manhattans and I would like to have one every now and then. The only problem is I am cheap and I don't want to buy a bottle of vermouth if it will not last me. I may only have 1 Manhattan a week and I usually don't use much Vermouth.
How long will a bottle of vermouth last once opened?
