Overview

Coffee is a brewed beverage made from the roasted seeds of evergreen shrubs in the genus Coffea. The two most commercially significant species are Coffea arabica (arabica) and Coffea canephora (robusta), which differ in flavor profile, caffeine content, and disease resistance. The drink is characterized by a bitter, acidic, and aromatic flavor that varies dramatically by origin, roast level, and brewing method.

Origin and history

The coffee plant is native to the highlands of Ethiopia, where the Oromo people are believed to have consumed the fruit and leaves before the beverage form emerged [1]. The earliest documented use of coffee as a drink dates to 15th-century Sufi monasteries in Yemen, where the beans were roasted and boiled to produce qahwa, a word that originally referred to wine [2]. Coffee spread through the Islamic world to Cairo, Mecca, and Istanbul, where the first coffeehouses (qahveh khaneh) appeared in the 16th century. European colonial powers introduced coffee cultivation to the Americas, Asia, and Africa in the 17th and 18th centuries, with Brazil becoming the world’s largest producer by the 19th century [2]. The plant’s global spread is tied to colonial plantation economies, forced labor, and later, the rise of fair-trade and specialty coffee movements.

Varieties and aliases

  • Coffea arabica (arabica) — the dominant species in specialty coffee; lower caffeine, higher acidity, more complex flavor.
  • Coffea canephora (robusta) — higher caffeine, more bitter, resistant to coffee leaf rust; used in espresso blends and instant coffee.
  • Coffea liberica (liberica) — grown in West Africa, Southeast Asia, and the Philippines; known as kapeng barako in Batangas, Philippines [3].
  • Coffea excelsa (excelsa) — a variety of liberica; grown in Southeast Asia and the Philippines; smoky, fruity profile.
  • Regional names: qahwa (Arabic), kape (Filipino), cà phê (Vietnamese), kahve (Turkish), café (Spanish/French).

Culinary uses

Coffee is most commonly consumed as a hot or iced brewed beverage, prepared through methods including drip filtration, espresso extraction, French press, cold brew, and percolation. It is used as a flavoring in desserts such as tiramisu, coffee cake, mocha cake, and ice cream. In savory cooking, coffee appears in dry rubs for meat, marinades, and sauces, particularly in American and Latin American barbecue traditions. Coffee is also an ingredient in cocktails (espresso martini, Irish coffee) and in some cuisines is brewed with spices such as cardamom (Arabic and Armenian coffee) or with condensed milk (Vietnamese cà phê sữa đá).

Cross-cuisine context

Coffee has no single analogue in Mexican cuisine, but it occupies a structural role similar to that of atole or champurrado as a hot, daily beverage consumed at breakfast and merienda. In the Philippines, coffee (kape) is similarly a morning staple, often paired with pandesal or broas biscuits, and the Batangas region’s kapeng barako (liberica) represents a distinct species not commonly found in Mexican coffee culture [3]. In Vietnamese cuisine, coffee is prepared with a phin filter and sweetened condensed milk, producing a thick, sweet drink that has no direct Mexican equivalent. In Arabic and Armenian traditions, coffee is brewed with cardamom and served unfiltered, a practice that parallels the use of spiced hot beverages in Mexican café de olla, which is brewed with cinnamon and piloncillo. In Peru, café pasado is a concentrated coffee essence kept in the home and diluted to taste, a preparation method distinct from the single-serve brewing common in Mexico.

Notes for cooks

  • Coffee beans lose freshness rapidly after roasting and grinding. For best flavor, buy whole beans and grind immediately before brewing.
  • The grind size must match the brewing method: coarse for French press, medium for drip, fine for espresso. Incorrect grind size produces under- or over-extraction.
  • Stored in an airtight container away from light, heat, and moisture, whole beans remain usable for 2 to 4 weeks after roasting. Do not refrigerate or freeze unless absolutely necessary, as condensation degrades flavor.
