Colombia was the biggest coffee trading partner of the United States in 2023, with the U.S. importing 1.55 billion dollars’ worth in that year. Brazil, another South American country known for its coffee tradition, was second, exporting over 1.5 billion dollars of coffee to the U.S. in the same year. Colombian coffee Colombia is well known for its coffee. The fictional character Juan Valdez, used in advertisements for the National Federation of Coffee Growers of Colombia, has become an icon in popular culture, instantly associated with Colombian coffee. In 2020, the country was the third largest coffee grower in the world, producing 14.3 million 60-kilogram bags of coffee. About 16 percent of the coffee imported by the United States from Colombia was Fair Trade certified in 2016. Fair trade is a movement which aims to improve conditions for workers in agriculture and the environmental sustainability of the crops harvested. In the same year, 22 million dollars of the imported coffee from Colombia was organic.

Coffee consumption in the United States amounted to over 26.3 million 60-kilogram bags in the 2022/2023 fiscal year. This is a slight decrease from the total U.S. coffee consumption in the previous fiscal year.

Coffee production The coffee plant has its origins in Ethiopia and is now grown all over the world. Most of the world’s coffee is cultivated in South America, followed by Asia and Oceania. In 2021, over 77 million 60-kilogram bags of coffee were produced in South America. The majority of South America’s coffee production is attributed to Brazil. In the 2020/2021 fiscal year, global coffee production reached 175 million 60-kilogram bags.

Coffee brewing in the United States Americans love their coffee and have dozens of different methods and gadgets for brewing and preparing coffee. A 2020 survey of U.S. consumers found that the most commonly used coffee preparation methods were drip coffee makers and single cup brewers. However, drip coffee makers have become less popular over time. In 2010, 77 percent of coffee drinkers used drip coffee makers, while in 2020 this share had dropped to 41 percent.

During the 2023/24 period, global coffee imports amounted to a total of 137 million 60-kilogram bags. In the same period, around 142 million bags were exported worldwide.

The industry is primarily fueled by two types of beans, Arabica and Robusta, with Arabica known for its milder flavor and Robusta for its higher caffeine content. This beverage is not only appreciated for its energizing effects due to caffeine but is also linked to potential health benefits, such as reducing the risk of liver cancer, protecting against Parkinson’s disease, and supporting heart health.

In recent years, coffee production has reached record highs. During the 2020/21 period, global coffee production exceeded 175 million 60-kilogram bags, making it the highest-yielding season to date. Production remained robust in 2021/22, reaching 168.5 million bags. South America continues to dominate coffee production, generating approximately 82 million bags in 2022, accounting for nearly half of global output. In terms of trade, the United States leads the world in coffee market revenue, generating approximately USD 85 billion, while Brazil, a major coffee producer, generated USD 35 billion in revenue.

In 2023, the U.S. emerged as the largest coffee importer globally, followed by Germany, Canada, and the Netherlands. Brazil, Switzerland, and Germany were the leading exporters. Sustainability has gained traction within the coffee industry, with over 1.5 million metric tons of sustainable coffee, certified by organizations such as UTZ, produced in 2022.

In the U.S., coffee consumption remains strong, with Americans consuming an average of two cups daily. Home remains the top location for consumption, and the leading ground coffee brands include Folgers and Starbucks. Emerging trends, such as cold brew coffee, have gained popularity, especially among younger consumers who prefer its stronger flavor and higher caffeine concentration compared to traditional brewed coffee.

In 2024, 67 percent of survey respondents in the United States stated that they drank coffee within the last day. About 26 percent of U.S. respondents had drunk espresso-based beverages instead. Coffee brands in the U.S. In 2020, Folgers produced over one billion U.S. dollars’ worth of sales in the United States, making it the leading brand of regular ground coffee by a significant margin. Total sales numbers generated by private coffee labels amounted to some 424 million U.S. dollars. Folgers Coffee was first introduced in 1850, and by 2020, had the largest ground coffee market share in the United States. The coffee giant was followed by other well-known brands, such as Maxwell House, Starbucks, and Dunkin’ Donuts. Arabica vs. Robusta In the commercial coffee industry, there are two main types of coffee species: Arabica and Robusta. Coffee beans of the Arabica variety are slightly larger, produce a smooth and aromatic taste, and are the most commonly produced coffee bean variety: in 2023/24, just over 97 million bags (60 kilograms each) of Arabica coffee were produced worldwide.

Covalent organic frameworks (COFs) are a versatile class of nanoporous materials that can be used for a broad range of applications. They possess strong covalent bonds and low densities. Owing to their building block nature, the number of hypothetical COFs envisioned by reticular synthesis is enormous. Since experimental screening is not possible, computational high-throughput screenings offer a valuable alternative to characterize the material space and speed-up materials discovery. These screening studies typically require a diverse materials database and accurate interatomic potentials to accurately predict the macroscopic behavior of each hypothetical COF. Here, we present ReDD-COFFEE, the Ready-to-use and Diverse Database of Covalent Organic Frameworks with Force field based Energy Evaluation. Our database contains 268 687 COFs and accompanying ab initio derived, system-specific force fields for each of them. We hope this database may inspire other researchers to further explore the potential of these intriguing functional materials.
