This article is the first in a series of SOE espresso experiments launched by Front Street Coffee, using Costa Rican Fuego Phoenix Estate Sapphire coffee beans to make espresso. These beans come from the Central Valley, at an altitude of 1600 meters, sun-dried, with varieties Caturra and Catuai. The article documents in detail the extraction parameters and flavor performance, and extends to pairing tests with milk coffee. Since the beans' roast level was originally more suited to pour-over, when used for SOE, the resting period needs to be extended and the extraction time lengthened to 35 seconds, in order to fully release the fermented aromas and avoid under-extraction. If you are interested in single-origin espresso, you may wish to refer to the parameters in this article to explore more possibilities with these beans. [more…]

When faced with a new bean, roasters typically start by gathering origin information and the flavor descriptions provided by the green bean supplier, then gradually adjust through test roasts and cupping.

In the Long Banga area of northeastern Sarawak, Malaysia, indigenous farmers are turning their attention to coffee cultivation, hoping to bring local coffee beans to the international market and to inject new vitality into local tourism through coffee estates. Sarawak's economy has long relied on oil, natural gas, rubber, and hardwood, and excessive logging has brought ecological pressure, with coffee and tourism seen as directions for transformation. The main local crop is Liberica, valued for its tolerance of low altitudes, strong disease resistance, larger fruit, and faster ripening. Although coffee was introduced in the 19th century, it faded into obscurity due to poor management and the priority given to pepper and rubber, and only in 2019 did a turning point arrive. Today, farmers run homestays while growing coffee, and the government also hopes to use historic buildings, rivers, and jungle resources to attract more tourists. [more…]

Pour-over coffee is inseparable from the dripper, but just how big is the dripper's influence on flavor? This article begins with the Melitta dripper, which went into production in 1912, and traces the story of the birth of the world's first trapezoidal dripper—Mrs. Melitta, inspired by blotting paper, poked holes in a brass cup to filter coffee, but because the filter paper was difficult to fit the cylindrical container, this gave rise to the prototype of the ribs. Afterward, the defect of slow flow in the single-hole design prompted the emergence of multi-hole versions. The article then focuses on the core elements of the dripper: flow rate and flow-guiding performance, and through actual testing of V60 and the Kono short-rib version with Front Street Coffee's Mandheling beans, reveals the practical effects of different drippers on extraction time, mouthfeel, and grinding adjustment.
