The Chef & Sommelier's Open 'up Spirits Ambient Glass 16.5cl / 5 3/4oz Case Size 24 is part of the Chef & Sommelier's Open Up collection. It’s remarkable and iconic shape, the extensive Open Up range has become the flagship technical stemware range, magnificently demonstrating the benefits and ingenious of performance glassware design. The shape creates an accelerated decanter effect that encourages aromas to develop. The large surface for oxygenation, that closed wines require, in the lower bowl helps the aromas develop, whilst the upper part of the glass concentrates the aroma, these elements all come together to allow instant enjoyment.
