If we talk about the shelf life of sweet vermouth, then you can keep an unopened bottle for 3 to 4 years.

Its flavors keep intact and similar until the bottle is closed and refrigerated.

However, the taste will not be the same if you open the bottle and store it for a long.

When the bottle is open the factors like heat, air, and moisture ruin the taste of the drink.

Thus one should keep the bottle closed if they are not planning to use it recently.

An opened bottle, if refrigerated, can only be good for two months; also, it can degrade in quality as time passes.

An open bottle of vermouth should be finished quickly, as keeping it safe from external factors is pretty hard.

Storage of the beverage in the pantry is not at all recommended as the drink cannot handle storage at a higher temperature.

How to Tell if Sweet Vermouth Has Gone Bad?

  • Off Smell.

When you do not remember the time of storing an open bottle, then before having it, you need to be sure that it is fine for drinking.

For that, you can look for signs that can indicate its freshness.

You can simply smell the bottle and see if it still holds that aromatic fragrance when it is fresh.

If it gives a good smell, you can have it, but if it’s a foul odor, you should avoid having the drink.

  • Change in Color.

Another sign one can notice a change in color because these drinks do not change their color frequently, but if they do, it indicates that the drink has gone bad.

Some of the wine sometimes turns a little dark when anyone prolongs their storage, but a drastic change in color means that it is not drinkable, and you should throw the beverage out.

  • Take a Sip.

You know how flavorful a sip of a sweet vermouth drink can be so that you can taste it.

Be sure that first, you look for a change in smell and color, as drinking a bad beverage can be harmful.

Thus tasting can help you a lot; if you are getting that same flavor, then you can have the drink as it is good.

However, if the taste turns out to be rancid or dull, you should immediately stop and discard the beverage.

  • Storage in Pantry.

As discussed above, better storage can help you to make your drink last more, so you need to store it correctly.

When the bottle is closed, then you can keep it in the pantry as it will be intact from all the external factors.

But if the bottle is opened, then heat and the high temperature of a pantry will make the oxidation process faster.

  • Storage in Fridge.

Once the sweet vermouth bottle is opened, you need a cool and dark place to store it.

Therefore fridge can be the best way to keep your drink.

Problems like pests and oxidations get eliminated by the lower temperature; thus, your beverage can be good for extended periods.

  • Use an Airtight Container.

An unopened bottle is entirely sealed, so it does not need any container, but once it’s open, you have to reseal it back.

For that, one can use an airtight container and keep the drink in the fridge and save it from moisture.


One can easily store their drink and exceed its shelf life for an extended period by the earlier provided storing measures.
