I am a big fan of the Spanish virgin olive oil at Costco (the one in the tall green bottle), so I got excited when I saw their olive oil from Italy. I thought it would also be great, but it tasted very very strange. I don't know what 'acrid' is, but the word sounds like what that oil tasted like.

Costco sells a few different Italian olive oils. The best flavor is the Toscano or Val di Mazara. (Which one they have varies from year to year.) They only have these for a while from late spring until they runs out, and it is the most recent October/November harvest. They are in tall square green bottles, perhaps similar to the Spanish you mention.

Yes, I should have been more specific. Out of the two italian olive oils in tall bottles, the one with the purple colors tasted bad to me. I think it says Italy on it in big letters. The green label bottle, also from Italy but which says Toscano, tasted just fine (though I still prefer the Spanish bottle).

Do you make sandwiches with olive oil and lettuce? Genuinely curious.

I'm not that commenter, but dipping toasted bread in olive oil is delicious. And with the lettuce, you can mix olive oil and balsamic with a bit of seasoning to make a simple vinaigrette for a dressing.

I am that commenter and exactly this (lemon is great too) The best there's some kind of cheese or fish around
