My grandmother knew how to keep things fresh. I don’t want to knock my mother — she froze everything — but Nonna understood what belonged in a tin and what absolutely did not.

Biscotti should never be frozen. They are twice baked to remove moisture. Freezing reintroduces that moisture, softens the crumb, and dulls flavor. If you freeze them, you undo everything that makes biscotti biscotti.

Below, you’ll find how long homemade biscotti really last, how to store them, how to re-crisp soft cookies, and how to tell when they’re truly past their prime.

How Long Does Homemade Biscotti Last?

The short answer: 2 weeks at room temperature. With airtight storage, many batches stay crisp for up to 1 month.

Moisture and humidity are the true enemies of biscotti. Keep both out, and your cookie jar stays perfect.

The Best Way to Store Homemade Biscotti

• Store in a sealed airtight container or classic tin.
• Keep them in a cool, dry spot, away from heat or sunlight.
• Avoid light — it dulls flavor and melts chocolate.
• For gifting: polypropylene heat-sealed bags work best (this is what we use at TBC).

Nonna’s way: a simple cookie tin kept in a dry cupboard. Still one of the best methods.

Should You Refrigerate or Freeze Biscotti?

• No freezing — ever.
• No refrigeration. Fridges introduce humidity and odors.
• Always store at room temperature in a sealed container.

Note: The Biscotti Company biscotti last six months unopened and one week after opening. That’s printed on every bag.

How to Refresh Soft Biscotti

If biscotti lose their crunch, warm them on a baking sheet at 300°F for 5–7 minutes. Cool fully before tasting. This removes absorbed moisture.

Store-bought biscotti respond well to this too.

Signs Your Biscotti Have Gone Bad

• Texture: limp, soggy, or won’t re-crisp.
• Flavor: flat, stale, or strangely sweet.
• Smell: sour, musty, or oily.
• Appearance: mold growth or greasy patches.

Final Thoughts

Biscotti last because they are simple, lean, twice baked, and low in moisture. With proper storage, you can enjoy that crisp, fragrant bite for weeks.
