Crystal material: High-quality whiskey glasses are typically made from crystal, which is a type of glass that is known for its clarity and durability. Crystal glasses are also heavier and more substantial than other types of glass, which adds a luxurious feel in the hand.
Narrow rim: The rim of a whiskey glass is usually narrow, which allows the liquid to flow smoothly into the mouth and helps to retain the aroma of the whiskey.
Thick base: The base of a whiskey glass is typically thicker than other types of glasses, which helps to prevent the glass from tipping over and spilling its contents.
Large bowl: The bowl of a whiskey glass is typically larger than other types of glasses, which allows for more surface area for the liquid to come into contact with the air and release its flavors and aromas.
Smooth finish: The surface of a whiskey glass is typically smooth and free of any imperfections, which helps to prevent any unwanted flavors or aromas from being imparted to the whiskey.
