What to Look for When Buying
- Freshness: Always check the expiration date on the jar. I prefer jars with the longest shelf life to ensure freshness.
- Packaging: Costco’s Castelvetrano Olives usually come in glass jars, which I find better than plastic because it preserves the flavor and prevents contamination.
- Brine Quality: The olives should be submerged in a clear brine without cloudiness or sediment. This indicates good preservation.
- Size and Texture: I like olives that are plump and firm, not shriveled or mushy. Castelvetrano olives should have a satisfying crunch when you bite into them.

- Added to pasta dishes or tapenades.
- Paired with cheese and charcuterie on a grazing board.
Storage Tips
Once opened, I keep the olives in their original brine and store the jar tightly sealed in the refrigerator. This keeps them fresh for several weeks. If the brine level drops, I sometimes top it off with a little salted water to maintain freshness.
Final Thoughts
If you’re looking to add a versatile and delicious olive to your kitchen staples, I highly recommend giving Costco’s Castelvetrano Olives a try. Their mild flavor and great value make them a favorite in my home. Just remember to check the freshness and store them properly to enjoy them at their best!
