Ice cream doesn’t "expire" in the traditional sense, but it does have a best-by date indicating peak quality. Commercial ice cream, when unopened and stored at 0°F (-18°C), can last 2–3 months beyond its printed date. However, factors like temperature fluctuations, packaging, and ingredients affect longevity. Homemade ice cream, lacking preservatives, typically lasts 1–2 weeks. While old ice cream isn’t always unsafe, its texture and flavor degrade over time.

4 Signs Your Ice Cream Has Gone Bad

Spotting spoiled ice cream is key to avoiding unpleasant experiences. Look for these red flags:

1. Freezer Burn

   • Appearance: Thick ice crystals or a dry, crumbly texture.

   • Cause: Exposure to air due to improper sealing.

   • Safety: Not harmful, but impacts taste and creaminess.

2. Unusual Texture

   • Grainy or icy ice cream signals fat separation or sugar crystallization from thawing and refreezing.

3. Off-Putting Odor or Taste

   • Sour, rancid, or "off" smells indicate oxidation or contamination.

   • Strange flavors (e.g., overly metallic or bitter) mean it’s time to toss it.

4. Mold Growth

   • Rare but possible if contaminated before freezing. Discard immediately if spotted.

How Long Does Ice Cream Last? Commercial vs. Homemade

• Unopened Commercial Ice Cream: 2–4 months past the best-by date (if stored correctly).

• Opened Commercial Ice Cream: 1–2 months. Cover the surface with parchment paper before resealing to minimize ice crystals.

• Homemade Ice Cream: 1–2 weeks due to lack of stabilizers. Use airtight containers to preserve freshness.

How to Store Ice Cream Properly

Maximize your ice cream’s shelf life with these tips:

• Keep It Airtight: Press plastic wrap against the surface before closing the lid to block air exposure.

• Avoid Temperature Swings: Store in the back of the freezer (not the door) to maintain 0°F (-18°C).

• Don’t Thaw and Refreeze: Partial melting breeds bacteria and ruins texture. If thawed, consume within 1–2 days.

• Use Shallow Containers for Homemade: Reduces crystallization and preserves creaminess.
