A true aerating pour spout is a type of spout designed to allow champagne, wine, and other carbonated beverages to naturally aerate as they are poured. These spouts are designed with sleek openings and a wide base in order to release more bubbles, as well as a narrow lip designed to make pouring accurate and precise. Additionally, the internal structure of a true aerating pour spout is designed to help minimize the formation of foam. Quality true aerating pour spouts are usually made of stainless steel or other corrosion-resistant materials for long-term use.
