This whisky glass is designed to enhance all whiskies and eaux-de-vie, such as Cognac and Armagnac. With a distinctive wide bowl, this technical glass will reveal the subtleties in the whisky, bringing out the aromas for an utterly indulgent tasting.The central dome is intended to divide the liquor and prevent an overpowering elevation of alcohol vapors to the nose. The metal base is designed to chill the spirit for at least 30 minutes, without upsetting it or creating a temperature shock that would inhibit the release of the scents, and without the use of ice. For better results, leave the metal base in the freezer for a few hours.
