Recently, many Luckin tea-coffee enthusiasts noticed a noticeable change in the flavor of their usual Jasmine Latte, suspecting that the brand had adjusted the recipe. In March of this year, Luckin had just announced an upgrade to its light milk tea, switching from tea powder to freshly brewed tea, and the Jasmine Latte was improved accordingly, with a fresh tea aroma that blended well with the coffee, making it a daily must-order for many consumers.

The AeroPress, with its极高 playability, attracts many coffee enthusiasts to get involved, and the official organization even holds专属 competitions every year to see who is the best at "playing" with it. In this article, Front Street is going to share a universal extraction recipe from an AeroPress champion—this champion is none other than粕谷哲, the 2016 World Coffee Championship winner and inventor of the famous 4:6 method.

Using an Ethiopian Hamashu light-to-medium roast floral and fruity bean as an example, Front Street records in detail the dose, grind size, water temperature, extraction time, and inverted pressure operation steps, and also provides by-pass dilution suggestions and flavor tasting references. Friends who have an AeroPress at home should definitely give it a try. [more…]

When faced with a coffee bean you've never encountered before, how do you quickly develop a suitable pour-over plan? This article starts with simplifying the brewing framework and shares a practical method: first roughly categorize coffee beans by roast level, establish a highly versatile brewing plan for each category, and then identify where unfamiliar beans belong through flavor descriptions and bean color. As experience accumulates, gradually refine the categories, deriving medium roast from light roast and dark roast, and even making further adjustments for special varieties such as Geisha. Front Street Coffee uses its own two brewing plans as examples to show that by keeping the dose, ratio, and technique consistent and adjusting only the water temperature, grind size, and dripper, most beans can be handled. This approach not only reduces decision-making costs but also leaves room for subsequent optimization. [more…]
