The Derwent mills are the epitomy of Cole & Mason style & elegance. Contemporary in design, they are made from clear acrylic. Featuring the Cole & Mason Gourmet Precision mechanisms; carbon steel for pepper that strips peppercorns instead of crushing them, and diamond-sharp ceramic for salt, ensuring maximum flavour release from every turn. The hardwearing qualities of these mechanisms ensure you will always receive a consistently outstanding performance. With 6 pre-selected grind settings for pepper, and 3 for salt, ranging from fine to coarse you will always find the best grind size to optimise the flavour of every meal. To clean, wipe with a damp cloth and use a clean cloth to dry. We recommend you do not use any cleaning products as this can affect the finish of the product. Do not immerse in water or place in a dishwasher. All Cole & Mason salt and pepper mills are covered by our lifetime mechanism guarantee. Should your mill not meet the high standards and expectations of Cole & Mason products we will be happy to replace your mill for an alternative of equivalent value. Accidental breakage, poor care and damage from misuse are not covered.
