Duerr’s English Traditional Strawberry Jam comes in a 3kg tub. Today, Duerr’s products can be found all over the world, as the company exports to over 30 different countries. Duerr’s remains very much a family business, and a member of the Duerr family has sat at the helm of the company since it's inception. This has ensured that the traditions so lovingly begun by Mary are adhered to today, with the emphasis on quality ingredients, innovation and manufacturing excellence.
