Designed to enhance all whiskies and eaux-de-vie, such as Cognac and Armagnac. https://www.cutleryandmore.com/peppermills.htm With a distinctive wide bowl, this technical glass will reveal the subtleties in the whisky, bringing out the aromas for an utterly indulgent tasting. To enjoy full benefits, the pour of whisky should be lower than the central dome, which is intended to divide the liquor and prevent an overpowering elevation of alcohol vapors to the nose. Thus, tasting in sheer perfection. 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. No need for water to open up the whisky; the stylish curves help release the subtle aromas while the central dome divides the liquor and prevents an overpowering elevation of alcohol vapors to the nose. For better results, leave the metal base in the freezer for a few hours.
