Farrington's Mellow Yellow Rapeseed Oil
Drive through the countryside in the late spring/early summer, and you will see field after field of vivid yellow flowers. This is rapeseed (Brassica napus), also known as oilseed rape. It's been a feature of our countryside, and agricultural production, for many years now, and the harvested oil is used for biodiesel, and for human consumption, in the form of rapeseed oil.
