Balsamic glaze is a thick, sweet and syrupy condiment that is made from reduced balsamic vinegar. It has become increasingly popular in recent years and can be used to drizzle over cheeses, fruits, desserts and more to add a sweet and tangy flavor. However, like most condiments, proper storage is important to maintain its quality and prevent spoilage.
Should balsamic glaze be refrigerated?
Yes, it is best to store balsamic glaze in the refrigerator after opening. The refrigeration will help slow down the growth of bacteria and mold and extend its shelf life. Specifically, an opened bottle of balsamic glaze will typically last about:
- Refrigerator: 6 to 12 months past the printed expiration date
- Pantry: Up to 6 months past the printed expiration date
So for maximum freshness, it is recommended to keep it refrigerated once opened. The pantry storage time is shorter because the higher room temperature promotes faster bacteria growth.
What container should balsamic glaze be stored in?
Balsamic glaze should be stored in an airtight, non-reactive container. Good options include:
- The original glass bottle with the lid tightly closed
- A squeeze bottle with an airtight cap
- A mason jar with an airtight lid
- Food storage containers with airtight lids
The key is choosing a non-reactive container, meaning something that will not react with the vinegar in the glaze. Materials to avoid include copper, aluminum and cast iron. Storing it in the original bottle is convenient, but for longer storage, transferring to an airtight container helps prevent any air exposure which can degrade the quality over time.
What temperature should balsamic glaze be stored at?
For best results, balsamic glaze should be refrigerated at 40°F (4°C) or less. The colder temperature inside the refrigerator will slow down bacteria growth and chemical reactions. Storing it at room temperature or warmer temperatures can shorten its shelf life.
While it can last for a shorter time in the pantry, it’s ideal to refrigerate an open bottle for maximum shelf life. Make sure to keep the refrigerator at the proper temperature and not over-crowded.
Can you freeze balsamic glaze?
Yes, balsamic glaze can be frozen for longer term storage. To freeze:
- Transfer the glaze to an airtight freezer-safe container, leaving about 1/2 inch at the top for expansion.
- Seal the container tightly.
- Label with the name and freeze date.
- Freeze for up to 6 months.
The acidic vinegar content means it is safe for freezing. Allow the frozen glaze to thaw overnight in the refrigerator before using. Mix well once thawed, as some separation may occur during freezing.
What happens if balsamic glaze goes bad?
There are a few signs that balsamic glaze has gone bad, including:
- Appearance: Liquid separating, oil on the top, mold development
- Texture: Becomes thinner and more watery
- Smell: Vinegar smell turns harsh or unpleasant
- Taste: Sour, sharp vinegary taste
A bottle of sealed, unopened balsamic glaze can last 2 to 3 years past the printed expiration date when stored properly in a cool, dark pantry. But once opened, it should be used within 6 to 12 months and discarded if it shows any signs of spoilage.
How can you tell if balsamic glaze has gone bad?
Here are some simple ways to tell if your opened bottle of balsamic glaze has spoiled:
- Check the expiration or “best by” date on the bottle. If it has passed, the glaze may be expired.
- Look at the consistency. Fresh glaze should have a thick, syrupy texture. If it looks thinner or separated, it may be bad.
- Smell the glaze. It should have a rich balsamic vinegar smell. An unpleasant or rotten odor means it’s no longer good.
- Taste a small amount. The flavor should be sweet and tangy, not harsh or sour.
- Look for any mold growth in the bottle or lids. This is a sign it should be discarded.
Trust your senses! If the glaze doesn’t look, smell or taste right, it should not be consumed and should be thrown out.
Conclusion
Balsamic glaze requires proper storage to maintain quality and freshness after opening. Keep it refrigerated in an airtight container, ideally its original bottle. Refrigeration at or below 40°F helps slow bacteria growth. It can also be frozen for longer storage up to 6 months. Use your senses to check for signs of spoilage and discard if expired or looking/smelling bad. Following these tips will help extend the shelf life of your balsamic glaze.
