Riedel recommends Miele.
Can delicate, expensive wine glasses really be washed in a dishwasher? Yes, as long as it's a Miele! With a unique combination of intelligent appliance features and the rinse aids from the Miele CareCollection, Miele is the specialist for gentle treatment of glasses.
The result: spotless, sparkling glasses that don't need to be polished. Even after numerous wash cycles, your valuable glassware will look as good as new. You can wash even high-quality, thin glasses in your Miele dishwasher without worrying, using Miele CareCollection products. Riedelglas, manufacturer and creator of wine glasses, has confirmed this. Georg Riedel recommends Miele dishwashers for washing his glasses (hand-blown and machine-blown).
