Goblets have some practical advantages that make them a popular choice for specific occasions and types of drinking:

1. Provide stability: The design of the goblet makes the bottom of the glass narrower and the body higher, which gives the glass better stability on the table, reducing the risk of collision and tipping.

2. Suitable for complex drinks: Tall glasses are usually used to serve complex drinks, such as cocktails, martinis, cocktails with ice, etc. These drinks usually require more preparation and decoration, and the appearance of the goblet is more suitable for displaying these exquisite drinks.

3. Drinking experience: The design of the glass makes the hand separate from the bottom of the glass when holding the glass, which helps to maintain the temperature of the drink, but also makes the hand not directly contact the body of the glass when drinking, keeping the temperature of the liquid in the glass stable.

4. Etiquette and formal occasions: Goblets are often seen as an elegant and formal drinking vessel and are therefore more common at formal occasions, dinners or parties.

While stemglasses have their advantages in the above areas, in everyday use, practicality may vary depending on personal preferences and drinking habits. Some people prefer a simple cup, while others prefer to use a goblet to add some special ambiance.
