Introduction

A cup of black coffee

Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes.

Coffee production begins when the seeds from coffee cherries (the Coffea plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask the bitter taste or enhance the flavor.

Though coffee is now a global commodity, it has a long history tied closely to food traditions around the Red Sea. Credible evidence of coffee drinking as the modern beverage subsequently appears in modern-day Yemen in southern Arabia in the middle of the 15th century in Sufi shrines, where coffee seeds were first roasted and brewed in a manner similar to how it is now prepared for drinking. Up to the end of the 17th century, Yemen was the world’s sole gateway for coffee. But as people everywhere developed a taste for it, the plant soon escaped its Arabian home and took root in distant soils. (Full article...)

UTZ, formerly called UTZ Certified, is a program and a label for sustainable farming. The organization was founded as a non-profit in the Netherlands in 2002. The UTZ label is featured on more than 10,000 product packages in over 116 countries. In 2014, UTZ was reported to be the largest program for sustainable farming of coffee and cocoa in the world. The UTZ program addresses agricultural practices, social and living conditions, farm management, and the environment. In January 2018, UTZ officially merged with the Rainforest Alliance in response to the increasing challenges of deforestation, climate change, systemic poverty, and social inequity.

Water seeps through the ground coffee and the paper filter and is then collected in a container placed below a holder used for drip brewing.

Drip coffee is made by pouring hot water onto ground coffee beans, allowing it to brew while seeping through. There are several methods for doing this, including using a filter. Terms used for the resulting coffee often reflect the method used, such as drip-brewed coffee, or, somewhat inaccurately, filtered coffee in general. Manually brewed drip coffee is typically referred to as pour-over coffee. Water seeps through the ground coffee, absorbing its constituent chemical compounds, and then passes through a filter. The used coffee grounds are retained in the filter, while the brewed coffee is collected in a vessel such as a carafe or pot. (Full article...)
