The Riedel Sommeliers Bordeaux Grand Cru glass, created in 1959 and refined over the years, is designed to enhance the experience of drinking Bordeaux wines. Crafted by the Austrian glassware company Riedel, it features a large bowl to allow the wine to breathe and concentrate its aromas. While opinions on the science behind such designs vary, many wine enthusiasts appreciate the attention to detail in these grape-specific glasses.
