What is a "tulip glass"?

A tulip glass is a type of stemmed glassware designed specifically for serving beer, particularly aromatic and flavorful styles such as Belgian ales and other craft beers. It is characterized by its bulbous body, which tapers inward towards the top to form a narrow opening, resembling the shape of a tulip flower. The design of the tulip glass helps to capture and concentrate the aromas of the beer, allowing the drinker to fully appreciate its complex flavors. The stem of the glass allows the drinker to hold the glass without warming the beer with their hands, while also providing stability.
