The Meridian Grapeseed Oil is the only oil in the Meridian range which is not organic and which requires refining. This is because an unrefined grapeseed oil, would be malodorous and unpalatable, however it is processed for the least possible time. The resulting oil is light and versatile, being good for frying and making mayonnaise.
