Yes probably Cook's Illustrated. IIRC they also liked the Colavita EVOO...I know it was one of the bigger commercial brands. I generally find their taste testing reviews to be pretty good. We don't use much balsamic, but I agree the Colavita aged is good. We also received a small production bottle a few years ago from a friend who visited Italy. There's still a bit left, like I said we don't use it much, mostly in a homemade salad dressing (rarely) or a drizzle over grilled vegetables. What else should I be using it for?
