With their distinctive and iconic shape, Chef & Sommelier Open Up Ardent brandy/cognac glasses make a statement. Their shape creates an accelerated decanter effect that encourages aromas to develop. A large surface area promotes oxygenation, allowing the spirit to breathe and develop, while the glass's upper section concentrates the aroma. Made from Krysta lead-free crystal glass, these flame-polished and finished glasses feature 30% more rim strength than standard crystal glassware. They are also dishwasher safe for quick and efficient turnaround of fresh glassware during busy services.
