Expiration & Storage Tips
When does vermouth expire?
Vermouth, being a fortified wine, has a longer shelf life than regular wines, but that doesn't mean it lasts indefinitely. An unopened bottle can easily last up to three to four years if stored properly in a cool, dark place. However, once opened, vermouth should be consumed within one to two months. Keeping it refrigerated after opening can slow oxidation and prolong its life up to an additional month. Freezing vermouth isn't usually recommended as it can alter its flavors and consistency.
How do you tell if vermouth is bad?
Telling if vermouth has gone bad can be tricky, especially if you're not a connoisseur. However, one fairly reliable way is to smell and taste it. If the vermouth gives off an off-putting, sometimes vinegar-like smell or tastes sour or overly bitter, it's likely past its prime and should be discarded. Another possible telltale sign of bad vermouth is a change in color - it can start to look darker and more murky than usual when it turns.
Tips for storing vermouth to extend shelf life
• Always reseal your vermouth tightly after each use to minimize its exposure to air. Vermouth, like other wines, oxidizes when exposed to air, affecting its flavor over time.
• Store opened vermouth in the refrigerator, not your liquor shelf. The cold temperature will help delay the oxidation process and keep it fresh longer.
• For even better preservation, consider pouring the vermouth into a smaller bottle once it's half-empty. The less air in the bottle, the longer the vermouth will keep its flavors.
• If you're buying vermouth primarily for cooking, consider buying smaller bottles so you can finish them quicker.
