What are ways to extend the shelf life of vermouth?

Well it depends a little on how you store it.  If you buy it in a glass bottle then you should store it in a cool dark place like a pantry or a closet.  If you buy it in a bottle in a box then you should store it in a cool dark place, but you can store it on a shelf or in the fridge if you put it in a sealed plastic bottle and put a little bit of liquid soap in the bottle and swirl it around for a few minutes.  If you want to store it for more than a few months you can put it in the freezer.

Your suggestion about the liquid soap does not sound right at all

It might not be right, but there’s nothing wrong with it.  When wine and alcohol are stored in a cool dark place for a long time they get stale and taste more like the container than the alcohol.  If you swirl some liquid soap around in a glass bottle, that will attract the harmful chemicals that make it smell stale.  If you swirl some liquid soap around in a bottle that’s in a box, it might evaporate and it won’t be in the bottle any more.  It doesn’t do much but it makes the alcohol smell better when you pour it, and it also tastes better.

That is absolutely not right. I looked it up and nothing about that comes up.

That’s too bad.   I hope that helps.  When it comes to vermouth, you want to keep it at a cold dark place.  It tastes good that way.  In a pantry, or in the basement.  You shouldn’t just open it to check if it’s safe, or check the bottle for mold.

Where should I store it after opening it in order for it to extend its shelf life?
