Cold pressing is the traditional and natural way to produce oil. Oil is simply gently squeezed out of the seed at temperatures below 40°C which ensures that the full essence and character of the oil is preserved. This careful process means that all the natural goodness within the seeds is preserved. Once the oil has settled, it is filtered to guarantee its purity, and then bottled. It is as simple as that - no heating, no refining - just pure, healthy rapeseed oil. Another important quality factor is that the rapeseed used in Farrington's MELLOW YELLOW is only pressed once and therefore the process is equivalent to Extra Virgin cold pressed olive oil. The whold process is natural which means that slight variations in character and appearance in the oil can be seen from season to season. However, through our careful selection of the finest seeds, and utmost care taken during the oil's production, we aim to produce the best quality cooking oil possible.
