A coffee cup is a container used for serving coffee and coffee-based drinks. There are three major types: conventional cups used with saucers, mugs used without saucers, and disposable cups made of paper or polystyrene foam (often mistaken for Styrofoam). Cups usually have a handle and may be insulated to keep the beverage hot longer. They can be made of glazed ceramic, porcelain, plastic, glass, insulated metal, and, most commonly, paper or polystyrene foam, sometimes called “Styrofoam”. A coffee cup sleeve is often placed over the cup to protect the drinker’s hands from the hot temperature of the beverage.

The shape of a cup influences how the coffee tastes. For example, a 2018 study by the Journal of Food Quality and Preference found that the shape of the mug affects the perception of aroma, acidity, and sweetness. In the experiment, experts and amateurs tasted coffee in a tulip-shaped mug, classic diner-style mug, and split cup. The tulip-shaped mug was deemed to have a stronger aroma and less acidity. The split cup was deemed to have more acidity and less sweetness than the other two.

Various sizes of coffee cups are used around the world, depending on the type of coffee served. Espresso is typically served in one, two, or three-ounce servings. Other coffees, such as Moka pot and Turkish coffee, are traditionally served in smaller cups because of the richness of each ounce. In North America, many people drink coffee shop style beverages in larger cups, such as Americanos and lattes. These drinks are typically more watered down than the strong espresso-style coffee served in other parts of the world.

A cup can also be shaped to enhance the appearance of the beverage or to promote brand identity. For instance, Starbucks and some other coffee shops use a unique shape of cup for their hot cocoa. Other companies such as Dunkin’ Donuts and McDonald’s have their own unique cups for their coffee.

Although it is technically possible to recycle coffee cups, it is challenging due to the design of the cups. In addition, the cups must be lined with a special material to provide critical resistance to liquids and resistance to fatty acids from milk and cream. This liner accounts for 5% to 10% of the total weight of the finished cup and is crucial to its performance.

A successful recycling process requires a consistent supply of used coffee cups and a reliable source of materials for converting them into recycled pulp. To help solve this challenge, a number of initiatives have been launched to encourage consumers to purchase and use reusable coffee cups. Some examples include Simple Cups, in the UK, which offers consumers a reusable cup that they can buy with a small deposit and return to participating stores for recycling; and the Muuse system in Freiburg, Germany, which provides residents with a hard-plastic OOH cup with a disposable lid that can be returned to any restaurant or café in the city for recycling.
