Once you have made all your olive oils, it is time to take the last few steps. The first thing is to taste them. Our How to Taste page features advice from an expert in the field. You can then blend different oils to achieve the taste profile you want for each of your finished products. If you want your oils to be certified as extra virgin, you will have to have them tested by a lab, and then sent to a certifying agency. Finally, of course, they have to be bottled and labeled.
