I usually get my olive oil at Trader Joe's (though I wonder if it's real olive oil), but I was out of it a couple of weeks ago and I was at Costco and decided to get their house brand: Cost Kirkland Filippo Berio Organic Extra Virgin Olive Oil. Bad call. The olive oil has a very nice olive oil scent, fresh and vibrant. But it has a bitter edge to it, it probably doesn't matter for cooking, but it's not too pleasant to eat with bread. I won't buy it again.
