Bring an old book, walk into a bookstore and exchange it for a cup of coffee — such a literary scene is now playing out in some bookstore cafés. A bookstore in Beijing launched a "books for coffee" campaign, but it sparked discussion online due to its strict requirements for used books — they must be hardcover bestsellers published within the past 20 years, with more than 200 pages and a price of at least 39 yuan, and professional textbooks, finance and economics titles, self-help "chicken soup" books, and children's books are explicitly rejected. Some people think a hardcover book is worth far more than a cup of coffee, while others feel the owner's conditions are entirely reasonable. This controversy over how to measure the value of books and coffee reflects the difficult problem bookstore cafés face in balancing sentiment with costs in their operations. [more…]

Water accounts for over 98% of brewed coffee, yet it has long been overlooked. Different types of water—RO water, tap water, mineral water, soft water, hard water—have a huge impact on extraction flavor. In 2014, Christopher Hendon and Maxwell Colonna-Dashwood published research revealing how sodium, calcium, and magnesium ions influence the extraction efficiency of flavor compounds, and subsequently published the book "Water for Coffee," which systematically discusses the dynamic balance between GH (total hardness) and KH (carbonate hardness), and proposes the reverse thinking of "Roasting to water." This article will sort out these key findings to help coffee lovers understand how water quality shapes the flavor in the cup, and will retain relevant recommendations for the Front Street brand.

As the Mid-Autumn Festival approaches, mooncakes are traditionally a festive treat for family reunions. However, this year, many consumers holding Starbucks mooncake redemption vouchers are far from happy. According to the voucher rules, customers were supposed to scan a code to make a reservation and pick up two gift boxes at a store. But in reality, nearby stores generally show no stock, customer service calls are stuck in long queues or even disconnected by the system, and store employees admit that the whole city is out of stock. From Beijing, Shanghai, Jiangsu, and Zhejiang to Chengdu and Wuhan, complaints about being unable to redeem the vouchers are pouring in, and Starbucks has yet to offer a unified explanation. This article will outline the sequence of events, the consumers' experiences, and industry commentary, and include the latest alternative solutions in some regions. [more…]

From late March to around Qingming, Guangdong often enters a mode of continuous rainfall. The weather forecast says it will rain, yet it occasionally clears up when you go out, making it hard to decide whether to bring an umbrella. There is an interesting little experiment circulating among the public: brew a cup of hot coffee, drop in a sugar cube, do not stir, and observe where the bubbles gather; this can roughly tell whether it will clear up or rain in the short term. This saying originates from the British writer Matthew Cole's *A Cup of Coffee Tells the Weather*, and it is actually related to the surface tension formed by coffee oils and the weather changes under the control of high and low atmospheric pressure. Of course, not all coffees are suitable; instant coffee and pour-over are not ideal choices. Freshly ground and freshly made hot Americano is more suitable, and the sugar should be sugar cubes rather than ordinary granulated sugar. [more…]

Yunnan coffee has gone through a tortuous journey: from missionaries introducing Typica, to large-scale cultivation in the 1960s to repay Soviet loans, to Nestlé promoting the Catimor variety in the 1980s.
