Among the three major coffee species, Arabica stands out with its exceptional quality, and famous varieties such as Typica, Bourbon, and Geisha all belong to it. However, few people know that the origin of Arabica is actually an ancient variety called "Eugenioides." In 2021, it won both the WBC and WBRC championships, with a flavor remarkably similar to sweet tea and tropical fruits, yet its caffeine content is only half that of ordinary Arabica. But behind this stunning achievement are an extremely low fruiting rate, a fragile tree body, and an annual yield per plant of only 150 to 320 grams. Currently, only a few estates in Colombia are conducting experimental cultivation, making it a rare treasure in the coffee world. [more…]

Pink Bourbon is a rare coffee variety bred by crossing Red Bourbon and Yellow Bourbon, and its coffee cherries take on a uniquely romantic pink color when ripe. However, maintaining this color is extremely difficult, because the color is determined by a recessive gene in the pollen grains, and the red and yellow genes easily interfere with each other, sometimes even producing Orange Bourbon. At present, Pink Bourbon is mainly found in Colombia and Guatemala. Take this batch of Front Street Coffee Colombia Pink Bourbon as an example: about 1,800 coffee trees, with each tree producing about 1.8 kilograms of fresh cherries per season, which after processing yield only about 0.36 kilograms of coffee beans, making the entire batch less than 650 kilograms and all the more precious. Its flavor carries sweet orange, sugarcane sweetness, a pleasant juicy mouthfeel, and small tomato notes, and is well worth savoring slowly by coffee lovers. [more…]

Typica Mejorado is one of the representative bean varieties of Ecuadorian specialty coffee. Although its name contains "Typica," it actually has no direct genetic relationship with Typica. It originated from a breeding trial project established by Nestlé in Pichincha Province, Ecuador, and was created by crossing Red Bourbon with Ethiopian native varieties. It became popular among local coffee farmers due to its outstanding pest resistance. At Ecuador's first COE in 2021, Typica Mejorado took 10 of the 23 winning beans scoring above 87 points, and its fame soared thereafter. This article will help you gain a comprehensive understanding of this rare variety from the perspectives of its origins, genetic identification, competition performance, and flavor characteristics.

SL28 is a rare coffee variety originating from the Lake Tanganyika region of East Africa. Discovered in 1931, it was selected and named by the Scott Laboratories. It has broad leaves with a slight reddish tint, adapts well to high-altitude environments, and possesses excellent drought and disease resistance. Its yield is also superior to traditional tree varieties, and its flavor is truly one of a kind. In the early twentieth century, French and British missionaries and researchers cultivated this Bourbon descendant in Kenya. Over a century, it adapted to the local soil with high phosphoric acid concentration, creating the distinctive acidity and aroma of Front Street Coffee's Kenyan coffee beans. Although SL28's yield fell short of expectations, it developed excellent sweetness, balance, and flavors of citrus and smoked plum. Currently, only a few estates in Central America are capable of cultivating it. This article will guide you through SL28's origins, genetic lineage, and flavor profile. [more…]

In the Melanesian archipelago of the South Pacific, New Caledonia is like a vibrant oasis, hiding one of the world's rarest, most expensive, and most unusual coffees. KOUANDJI Estate is located at the foot of the mountains about 25 kilometers southeast of the capital, Nouméa, and is dedicated to reviving the region's nearly vanished coffee-growing industry.

On the highlands of Sumatra, Indonesia, grows a coffee that once captivated the European royal courts—Lasuna. Over four hundred years ago, the Dutch introduced this Arabica variety to Indonesia, and from then on, under the name "Traveler's Coffee," it journeyed across the oceans to become an expensive beverage that swept Europe for two centuries. Yet times have changed, and today pure-blooded Lasuna survives only on about 500 hectares of farmland in the Takengon region, where the trees are all over half a century old, sustained by manual harvesting and traditional Dutch processing methods—the last vestige of its lineage. According to the Indonesian Coffee Association, this variety may vanish entirely within twenty years. Front Street Coffee takes you deep into this rare bean, which combines caramel sweetness, chocolate aroma, and a delicate oily mouthfeel, so you can experience its unique charm—rich, mellow, and with a long, lingering finish.
