How Long Does Herbal Tea Last Unopened?
Unopened herbal tea typically lasts 1.5 to 3 years when stored properly in a cool, dry place.
Key factors affecting unopened herbal tea shelf life:
-
Type of herbs used
-
Packaging quality (foil, airtight, paper)
-
Storage conditions (humidity, heat, light)
Loose leaf herbal tea usually lasts longer than tea bags because it is less processed and often sealed better. Commercially packaged herbal tea with foil wrapping generally stays fresh longer than handmade or artisanal blends.
How Long Does Herbal Tea Last After Opening?
Once opened, herbal tea lasts about 6 to 12 months if stored correctly.
Shelf life after opening:
-
Tea bags: 6–12 months
-
Loose leaf herbal tea: 8–18 months
Exposure to air and moisture is the biggest enemy of herbal tea freshness. If herbal tea absorbs humidity, it can lose flavor quickly or develop mold.
Tip: Always reseal tea tightly or transfer it to an airtight container.
How Long Does Brewed Herbal Tea Last?
Brewed herbal tea has a much shorter shelf life than dry tea.
Brewed herbal tea shelf life:
-
At room temperature: 6–8 hours
-
In the fridge: 3–5 days
-
Frozen: Up to 6 months (quality may decline)
Bacteria can grow quickly once tea cools, especially if sugar, honey, fruit, or milk is added.
How Long Does Herbal Tea Last in the Fridge?
When stored in a sealed glass or BPA-free container, herbal tea lasts 3 to 5 days in the refrigerator.
Signs refrigerated herbal tea has gone bad:
-
Cloudy appearance
-
Sour or musty smell
-
Slimy texture
If any of these signs appear, discard the tea immediately.
How Long Does Herbal Tea Last at Room Temperature?
Brewed herbal tea should not sit out longer than 8 hours at room temperature.
Warm environments accelerate bacterial growth, especially in sweetened teas. For safety, refrigerate leftover tea within 2 hours of brewing.
How Long Does Herbal Tea Last in the Freezer?
You can freeze herbal tea for up to 6 months.
Best freezing practices:
-
Use airtight containers or ice cube trays
-
Leave room for expansion
-
Label with date
Freezing preserves safety but may slightly reduce flavor and aroma.
Does Herbal Tea Expire?
Yes, herbal tea does expire, but it usually loses potency before becoming unsafe.
Expiration vs quality:
-
Past best-by date: Flavor and benefits decline
-
Visible mold or bad smell: Unsafe to drink
You can often drink herbal tea 6–12 months past expiration if it’s dry, mold-free, and smells normal but quality will be lower.
How to Tell If Herbal Tea Has Gone Bad
Signs herbal tea is bad:
-
Mold spots on tea bags or leaves
-
Musty or sour smell
-
Faded color or weak aroma
-
Bitter or unpleasant taste
Never drink tea with visible mold even if brewed.
