Trader Giotto's Sicilian Seleccion Extra Virgin. Has a light, pleasant grassy taste and no aftertaste. We taste tested with the TJ Spanish Extra Virgin and found the Spanish oil had a decidedly bitter aftertaste.
Not specifically olive oil but I just had some of their white truffle oil drizzled on some lobster bisque. It was really *very* nice. I've had truffle oils that barely could be tasted. But this held up marvelously to a full-bodied soup.
