How to Store Red Wine Vinegar Properly?
Due to the nature and chemical composition of red wine vinegar, there is no need to refrigerate it. Instead, you can just store it in a dark and dry place.
For unopened red wine vinegar, you can store it just about anywhere away from heat like in the pantry cabinet or cupboard.
This should be obvious as heat is the prime cause for spoiling any food.
For an opened bottle of red wine vinegar, the preliminary precautions remain the same with one additional thing to take note of.
Make sure the lid of the container is tightly sealed. Failing to do so will make the liquid more susceptible to rapid evaporation, making it lose its taste faster than usual.
- Keep the lid of the bottle sealed tight
- Store in absence of sunlight or heat
- A double-safe measure would be to use waterproof tape on the lid
All in all, red wine vinegar rarely goes bad and has an indefinite shelf life only with taste degradation.
It will remain safe to consume with just a change in taste.
Thus, to achieve the best taste, it is recommended to replace your bottle with a new one every 3-4 years.
Does Red Wine Vinegar Go Bad? How Long Does Red Wine Vinegar Last?
Let’s start with the elephant in the room – does red wine vinegar go bad? In simple words, it does not. However, that’s only a part of the answer.
You see, red wine vinegar is essentially an acid produced from the fermentation of red wine, meaning that it has a low pH.
This plays a vital role in preventing it from spoiling (source).
That’s because most bacteria that spoil food are unable to thrive at such a pH. Hence, the major reason that makes food rot is not present.
However, there is a catch to this: the red wine vinegar suffers from taste degradation.
While it has an infinite shelf life, over time, that taste becomes duller and less punchy.
It is for this reason that manufacturers generally give it a Best By date of 2-3 years.
This holds true for both opened and unopened red wine vinegar, provided that the opened bottle is tightly sealed.
The expiry date just indicated the period during which it is will taste the best.
