Q: Do olive oils really expire? I have two great bottles at home, and being single, and not home often, they have passed their expiration dates printed on the bottle. I’m still using them, as they don’t smell any different.

Are they still safe, or should I get new ones? And if they are bad, what’s a good way to dispose of leftover olive oil?

Editor: Rose, olive oil is definitely best used within a year, but if it hasn’t developed bitter or rancid flavors, then sure, it’s fine to use. Make sure you store it in a dark, cool place (see this post for more tips).

Readers, have you ever had olive oil go bad? What did it taste like?
