Oil is just one letter short of being a four letter word as processed foods in general are widely condemned. Yet there are good-for -you virgin oils such as walnut, olive, grapeseed, avocado, sesame and others that are not fully refined, stripped of nutritional benefits.   Matthieu Kohlmeyer knows good oils start with good farming. He set out from France for Northern California to build a company from scratch taking high-quality walnuts, drying them, and then toasting them in custom-made, French cast-iron kettles before pressing them to extract pure, "virgin" oil. At the time  walnut oils available in the United States were overly heavy or diluted with cheaper oil. Consumers took to La Tourangelle’s trich tasting, artisan oil full of "good-for-you" omega-3 fatty acids. From the farm to our tables, byproducts of well grown produce such as non vegetable virgin oils offer flavor, nutrition and climate smart production for consumers who care more than ever. www.latourangelle.com
