On United flights, which drinks should not be served in highball glasses?

In onboard service, the choice of glassware for different types of beverages is influenced by standard serving practices and customer experience. Highball glasses are typically used for serving cocktails and mixed drinks, which include spirits like whiskey or rum.

Coffee and wine, while popular beverages, are generally not served in highball glasses. Coffee is traditionally served in coffee cups or mugs, designed for heat retention and comfort while drinking. Wine, on the other hand, is best served in specific glassware that enhances its aromas and flavors, such as a wine glass that is shaped to focus the bouquet of the wine and allow for the swirling motion that releases its full aromatic profile.

Therefore, identifying coffee and wine as drinks that should not be served in highball glasses is accurate based on these traditional serving conventions. This ensures that the experience of consuming these beverages aligns with the expected norms and enhances customer satisfaction during the flight.
