Expiration & Storage Tips
When does tarragon vinegar expire?
Generally, tarragon vinegar can last upwards of 5 years unopened, and remains good for about 1-2 years after opening if stored properly. It is important to remember that the shelf life can be dependent on the best-by-date printed on the bottle, so make sure to check that. If the vinegar was homemade, the shelf life may be shorter, typically around 6 to 8 months. If frozen, it can last indefinitely but may lose flavor over time.
How do you tell if tarragon vinegar is bad?
To tell if your tarragon vinegar has gone bad, first take a look at it. If it has developed an off color or if you see mold growing, that's an immediate red flag. Then, give it a good sniff - a spoiled vinegar will have a strong, unpleasant smell usually characterised by a nose-piercing, sharp scent. Lastly, if you’re up to it, you can taste it – any flavor other than a sharp, bright, tangy one accompanied by subtle sweetness and tarragon's distinctive anise-like notes, may signal the vinegar has gone bad.
Tips for storing tarragon vinegar to extend shelf life
• Always store tarragon vinegar in a cool, dark place like a pantry or cellar.
• Ensure the seal of the bottle is closed tightly after each use to help extend its shelf life.
• Avoid using metal containers or utensils when handling vinegar as it can react and change the flavor profile. Opt for glass or ceramic instead.
• If you have a large quantity of vinegar, consider storing it in smaller glass containers. This will reduce its exposure to air each time you open it.
• Freezing tarragon vinegar is an option but consider it a last resort as it can change the texture and taste. To defrost, simply move it to the refrigerator to thaw slowly.
