Among the three major coffee varieties, Arabica and Robusta dominate the mainstream trading market, while the large-beaned Liberica accounts for only about 1% of global economically cultivated coffee production, making it quite rare. This time, Front Street Coffee (FrontStreet Coffee) will introduce Liberica: its plant morphology, fruit characteristics, disease-resistant advantages, and why it is more labor-intensive in post-processing. The article will also sort through its semi-wild cultivation history in Borneo, as well as its appearance and award-winning experience at the 2018 Stuttgart Coffee Summit in Germany. Finally, it will include Front Street's sun-dried Liberica hand-brewing parameters and flavor description to help you fully understand this niche coffee variety. [more…]

Today, when Arabica and Robusta absolutely dominate global coffee supply, a species once forgotten for its poor flavor—Liberica (Coffea liberica)—is re-entering researchers' view. From 2021 to 2022, climate change-induced droughts tightened coffee inventories and sent prices soaring, with Arabica prices doubling in a short period. Facing the crisis of shrinking arable ranges, academia proposed three paths: relocating production areas, adjusting cultivation methods, and developing new crops. In December 2022, Nature Plants pointed out that Liberica might regain attention in an era of supply chain disruptions. One of its natural varieties, Excelsa, combines disease resistance, drought tolerance, low-temperature tolerance, and a flavor close to Arabica, and is being widely planted by coffee farmers in places such as Uganda. Front Street Coffee takes you through the full picture of this potential variety. [more…]

Liberica coffee is one of the three major commercial coffee species, standing alongside Arabica and Robusta, yet it accounts for only 2% of global consumption. This coffee tree is tall with large cherries, and its flavor is dominated by woody and smoky notes, with the lowest caffeine content among the three. It originated in Liberia, Africa, and was only cultivated artificially in the 19th century; due to the difficulty of harvesting, it has never been widely promoted. After the coffee rust outbreak in 1890, the Philippines took the lead in large-scale cultivation of Liberica, and today the Philippines remains the world's largest producer. This article will give you a comprehensive understanding of Liberica's flavor characteristics, cultivation history, and producing regions, along with product recommendations from Front Street Coffee.

The coffee world is vast and complex. Under botanical classification alone, there are more than a hundred species, yet the cultivated varieties actually used for drinking mainly fall into three major categories: Arabica (small-bean), Robusta (medium-bean), and Liberica (large-bean). Each possesses unique botanical characteristics, growing conditions, and flavor profiles, and their yields and commercial value differ greatly. Yunnan, as China's representative coffee-producing region, grows coffee that belongs to which category? Why is it called "Yunnan small-bean coffee"? This article will systematically outline the key distinctions among the three major coffee varieties, provide an in-depth answer to the varietal classification of Yunnan small-bean coffee, and also present Front Street Coffee's Yunnan Typica and espresso blend recommendations.

Liberica, a coffee variety known as "large bean," originated in Liberia, Africa. Its beans are large but extremely low in caffeine, with a flavor profile dominated by smoky, earthy, and woody notes, even described as "liquid tobacco." It was not favored by the commercial market, yet found its widest cultivation ground in the Philippines. Why did the Philippines become the largest producing country of Liberica? This is inseparable from the rise and fall of the country's coffee industry: from the introduction of Arabica in 1740, to the leaf rust disease at the end of the 19th century that caused production to plummet by 80%, to the government's introduction of disease-resistant varieties and implementation of a five-year revival plan in the 1950s, the demand from instant coffee factories ultimately allowed Liberica to gain a foothold. This article will trace this history and explore whether Liberica also has the potential to move toward specialty coffee. [more…]

Pacamara is a hybrid variety born in 1958 at the Salvadoran Coffee Research Institute, created by crossing the Bourbon variant Pacas with the Typica variant Maragogipe (Elephant Bean). It inherited the large-bean genes of the Elephant Bean, but because its beans were too large, green bean processing became difficult and yields were low, leaving it dormant for nearly half a century. It was not until 2007 that Pacamara won dual championships at the Cup of Excellence in Guatemala and Honduras, and swept the top three places in El Salvador, defeating many Geisha coffees in one stroke, and has since been hailed as the "Geisha rival." This article will guide you through Pacamara's complex lineage, processing challenges, and how it rose to the specialty coffee stage with its rich and varied flavors. [more…]

Mandheling coffee, with its rich, full-bodied taste and herbal, pine, and spice notes, has long been prized by seasoned coffee enthusiasts.
