The Riesling Grand Cru/Zinfandel glass is perfect for balancing the high acidity and residual sugar of fruit-forward white and red wines. This shape is the most versatile white wine glass in the RIEDEL range, however it also works perfectly well for a few red wines, like Zinfandel. It helps to balance the fresh characters and high mineral components, emphasising the wonderful fruit aromas.Sommeliers was the world’s first wine friendly glass collection and a design revolution created by Claus J. Riedel (9th generation). The range adheres to the Bauhaus design principle of form follows function, as Claus J. Riedel had discovered that certain wines showed more depth and better balance when enjoyed from certain shapes. Thin-blown and unadorned, Sommeliers was the beginning of RIEDEL's dominance of the global wine glass market. This product is handmade. Our master glassmakers individually craft each item so every piece has a unique character. Due to the nature of crafting, small tolerances in the size and weight of each product, tiny bubbles, imperfections, or slight surface variations are an acceptable part of the process.
