The acidity in coffee beans does not refer to pH value, but is one of the basic taste characteristics that, together with body, aroma, sweetness, bitterness, and aftertaste, make up the overall flavor. Acidity is generally related to the roast level of the coffee beans and is also somewhat connected to the flavor of their growing region. Many people do not accept coffee that is too acidic because they find the taste too harsh. So [more…]

We all know that green coffee beans cannot be directly ground, extracted, or drunk. They need to undergo one more round of processing—roasting—before they can be brewed and tasted.

Front Street Coffee recently came across a uniquely shaped pour-over filter paper—the dual-chamber filter from Spain's Sibarist. Because its interior is divided in two by a partition, netizens have jokingly dubbed it the "double-flavor hot pot filter." The original design intent was to let coffee beans with different characteristics each be extracted separately in a single brew, but at 37.44 euros for 30 sheets—about 9.4 yuan per sheet—it really is staggering as a disposable consumable. Front Street Coffee decided to make a DIY alternative, using two 01-size filter papers in a 02 conical dripper to replicate the dual-chamber structure, and to explore the water temperature and other parameters that need to be considered when actually brewing with this kind of filter. This article will walk you through the dual-chamber filter's construction principle, its official pricing, how to make a DIY alternative, and the core considerations for using it, so you can see whether it's worth buying.

A barista's job may look leisurely, but in reality it's a tight rhythm—dialing in equipment, pulling espresso, cleaning gear, organizing supplies, and welcoming all kinds of customers, all of which must be juggled at once. However, customers don't walk in every moment, nor does the machine always need cleaning or calibration. During idle periods, besides the usual routines like practicing latte art, sorting defective beans, testing new beans, and flipping through coffee books, what other ways do they have to pass the time? The answers are all over the map: some scroll through their phones to check on fellow baristas, some make themselves madeleine-style shortbread for comfort, some arrange their pucks in neat rows, and some fold towels with obsessive-compulsive-level satisfaction. The artistic types hand-draw posters and DIY cups and paper bags, while the casual types play with stones, take naps, or even iron wrinkled clothes with a milk pitcher filled with hot water. Of course, some baristas are so busy behind the bar they're practically flying. This article takes you on a peek into baristas' amusing idle moments, and along the way, a taste of the great beans recommended by Front Street Coffee. [more…]

Many people wonder why some teas have the characters "single bush" in their names—like the common Phoenix Dancong, aged Phoenix Dancong, and frozen Wudong Dancong. To understand this naming convention, we need to start with the definition of Phoenix Dancong: it is made by selecting superior individual bushes from the Phoenix Shuixian population, which are then cultivated, picked, processed, and sold separately. These tea trees, processed using the single-bush method, are collectively called Phoenix Dancong. In contrast is the blending process used for Pu'er tea: to create different flavors, tea makers blend leaves from different mountains, seasons, and tenderness levels. Of course, some Pu'er enthusiasts prefer single-bush ancient tree tea. It is precisely for the convenience of cultivation and management, picking and processing, and consumer purchasing that Phoenix tea farmers classify and name tea trees based on tree morphology, finished tea characteristics, and growing environment. Accumulated over generations, this has formed hundreds of strains and varieties. This article will explain the issues everyone cares about regarding Wudong Dancong: its tin box packaging, market price, shelf life, and storage time. [more…]
