We have tried several different olive oil brands as our primary cooking oil, and we finally discovered Terra Delyssa. I'm not an expert, but I can clearly tell the difference compared to other brands. In terms of taste, quality, and aroma, Terra Delyssa is better than any olive oil we’ve tried so far. My wife likes it so much, too. I'm a repeat customer, and it seems likely that we’ll continue purchasing it in the future.
