The short answer is no. While a huge marketing push by the industry has led you to believe that the shape of the glass makes a difference, science says it doesn’t. The shape of the glass mostly affects how quickly the wine flows into your mouth and where it lands. If you want the wine to go directly to the back of your throat, a narrow glass will achieve this best. If you want your wine to be evenly distributed so you can savor it and experience the taste for longer, a wider bowl will slow the flow and make the wine feel smoother.
