Coffee cup

A coffee cup is a specialized vessel designed for serving coffee and various coffee-based beverages.

These containers serve many roles in social and commercial settings. There are three primary categories of coffee ware used today. Conventional cups are designed to be used with a matching saucer. Mugs are larger vessels that generally do not require a saucer. Disposable cups are intended for single use, often for customers on the go. These disposable options frequently utilize insulating sleeves to protect hands from heat.

Different drinks require specific cup shapes and volumes to ensure the best experience. Espresso is typically served in small white china demitasse cups. The Italian Espresso National Institute recommends these hold between 50 and 100 ml. An espresso macchiato is also served in this demitasse style. For a cappuccino, the same institute recommends a china cup holding approximately 160 ml.

In some formal settings, a small straight-sided cup called a "coffee can" is used. These are about 2.5 inches high and usually feature a flared profile. Cafes also use larger porcelain cups for drinks like lattes and mochas. These can hold volumes of 225, 336, 460, or even 570 ml.

Such shapes are often designed to assist baristas in creating latte art.

Specialized environments require highly engineered drinkware to function correctly. NASA designed "Space Cups," also known as Capillary Cups, for astronauts on the International Space Station.

In zero-gravity, liquid does not behave as it does on Earth. The Space Cup features a sharp inner corner to encourage capillary flow. This process allows the liquid to move toward the drinker's lips. Data from these cups helps engineers design better fluid systems for space. This technology can also improve medical blood testers on Earth.

History shows that coffee ware evolved from simple bowls into complex forms. Coffee cups and related items originated in the Middle East. In the 17th century, people used small, handle-less "Greek cups" to consume coffee. These were often made of Chinese or Japanese export porcelain. These early cups were tall to allow drinkers to consume the top liquid layer. This helped leave the sediment at the bottom of the vessel.

In Europe, Meissen porcelain cups appeared around 1710. Handles first appeared on some Meissen tall cups during this decade. By the 1730s, handles became a common feature of coffee ware. As drip coffee became popular in the 18th century, cup shapes became shorter. Sèvres porcelain pioneered these shorter designs to meet changing tastes.

Materials used in production have changed significantly over many centuries. Historically, manufacturers used bone, clay, or wood to create vessels. Modern coffee cups are commonly made of glazed ceramic, porcelain, glass, or plastic. Some versions are made of insulated or uninsulated metal. Disposable cups are often made of paper or polystyrene foam. Polystyrene, often called "styrofoam," is used because of its high insulating abilities.

Some paper cups are lined with wax or plastic to prevent leaking. However, some bamboo fiber cups have faced scrutiny from health agencies. In the UK, the Food Standards Agency advised retailers to withdraw bamboo cups in 2023. This was due to concerns regarding the melamine and formaldehyde in the glue.

Modern convenience has led to the rise of many disposable accessories. The first patent for a coffee cup lid was filed in 1967. Early designs required consumers to tear into the lid to drink. The 1980s saw an increase in "drink-through" lid patents. In 1986, the Solo Traveler lid was created. Later designs, like the Viora, improved on earlier venting systems. The coffee lid market was valued at roughly $180 million in 2009. In the United States alone, an estimated 14 billion lids were sold that year. Jay Sorensen also patented the cylindrical coffee sleeve in 1993 to provide insulation.

Environmental impact is a major concern regarding modern coffee consumption. The United States uses approximately 120 billion disposable cups every year. Most of these items eventually end up in landfills. Polystyrene foam cups are often non-biodegradable and contribute to marine litter. Some U.S. cities, such as San Francisco and Portland, have banned these foam containers. Paper cups also present challenges because they are lined with polyethylene. This makes them difficult to recycle and can release microplastic nanoparticles. Consequently, many consumers are turning to reusable cups to promote sustainability.
