Two decades ago, Maximilian J. Riedel redefined the way wine enthusiasts enjoy their favorite vintages with the introduction of his wine glass collection, RIEDEL O Tumbler. Over the years, the O Tumbler collection has evolved into versatile, multi-functional glasses suitable not only for wines but used as water glasses and other alcoholic and non-alcoholic beverages. Notably, the former Big O Pinot Noir tumbler has earned its place as the number one choice for gin enthusiasts, marking a significant milestone in the success of the collection.
