The specially shaped glass reveals the qualities and subtleties of whiskey, cognac, scotch, brandy, Armagnacs, and more while cutting down on the alcohol vapors. It comes paired with a metal chilling base and a branded Peugeot coaster so you can savor a single malt as it was meant to be enjoyed. No ice needed – enjoy it neat! Keep the chilling base in the freezer for a few hours until frozen then place on the coaster to prevent condensation rings. Set the glass over the base and pour the spirit without covering the dome. Wait for 2-3 minutes, or until the content has chilled to about 41 - 46°F (5-8°C). The whisky is now at the perfect temperature, yet not watered down, for a more authentic flavor.
