Releasing aromas: Enjoying wine is all about aromas. It’s the same joy as smelling bacon frying or sniffing a hot cup of Chai tea. With wine, the aromas are released as the alcohol volatilizes from the surface of the wine. Having an increased surface area is a benefit to optimize releasing aromas while drinking. There have been studies to show how swirling wine increases surface area.http://www.zbxuanwang.com/glass-mug/
