The long, thin shape of the Cornetto makes it perfect for both decanting young wines and removing sediment from older wines. The slim design of this decanter means there is a smaller surface area exposed, so fragile older wines are not over exposed to oxygen. This decanter is designed for a single bottle of wine. This pack contains a single piece. This product is handmade. Please hand wash only. RIEDEL recommends: Use bottle cleaners to remove stains from the decanter.
