Understanding how altitude affects flavor can help pour-over enthusiasts choose regional beans more precisely. The core advantage of high-altitude regions lies in the temperature difference between day and night. [more…]

More than one hundred confirmed species exist under the genus Coffea, among which Arabica and Robusta are the two names with the highest commercial value. But many people do not know that these two are actually not at the same taxonomic level—Arabica is a complete species, while Robusta is merely a variety under the Canephora species, ranking at the same level as Geisha and Typica within the Arabica branch. This article will clarify the differences and connections among these three from the perspectives of taxonomic relationships, growing conditions, flavor performance, and commercial uses, and will also explain why a small amount of Robusta is often added to espresso blends, as well as Front Street Coffee's specific approach in this regard with its classic blend.

As the world's fourth-largest coffee producer, Indonesia is facing severe climate challenges. From the relentless downpours brought by La Niña to the severe droughts triggered by El Niño, extreme weather has alternately battered coffee-growing regions, causing poor development of coffee flowers, withered leaves, and worsening pests and diseases. Industry insiders predict that Indonesia's total coffee production this season will plummet to less than 10 million bags, the lowest level in more than a decade. Smallholder farmers in low-altitude growing regions are bearing the brunt, with some even facing the prospect of a total crop failure. At the same time, soaring rice prices have prompted the government to encourage farmers to switch to rice cultivation, while the slow renewal of coffee trees further constrains any recovery in production capacity. Climate change could also lead to a sharp reduction in Indonesia's land suitable for coffee cultivation. Front Street Coffee will continue to follow subsequent developments in this growing region.
