From a recent post:
I've been using two 'Great' olive oils lately.
One is the 'house' olive oil from Alex Farm, which they import from Greece by the barrel. Following is the description on their website: "This extra virgin olive oil is stone pressed, giving it a thick full olive flavour complimented by a slight bitterness in the finish; a sign of pure oil". Alex Farm sells two kinds: one that starts with a K and the other with an M. I can't remember the names. I use the one with a K; it is the stronger, more flavourful of the two.
The other one, which also comes in bulk, is in the basement of St. Lawrence Market (the place at the northwest of the basement). They bring in barrels and sell one litre plastic jugs for about 10 bucks. Also great stuff.
Anyone have other suggestions for great olive oils?
