Coffee consumption continues to heat up, and the market keeps penetrating into broader demographics. Recently, home cafés and independent shops have launched a freshly ground and freshly extracted espresso liquid that offers nationwide free shipping.

This article sorts out the selling points, controversies, and potential risks of this new business format, and highlights the difficulties merchants need to face in quality control, marketing, and compliance.

Although drip bag coffee may be labeled with a shelf life of up to 12 to 18 months, the window during which its flavor is truly at its best is very short.

Cold brew coffee typically requires a steeping time of more than 8 hours, followed by a period of maturation to reveal its full flavor. But many coffee enthusiasts want to shorten the waiting time, so some bloggers have shared a method for "making high-sweetness cold brew in one minute"—using a hand press or espresso machine to extract with cold water at 9 bar of pressure.

This article analyzes in detail the principles and limitations of rapid cold brew, explains why flavor compounds cannot be fully dissolved at low temperatures even under pressure, and offers a more feasible way to shorten the time: appropriately raising the initial steeping water temperature. It also answers common questions such as how long cold brew coffee can be stored. [more…]

The flavor profile of a milk coffee ultimately depends on two core ingredients—espresso and milk. In a latte, milk often accounts for more than three-quarters of the drink; it must both carry the coffee's aroma and retain its own sweetness, while the coffee beans directly determine the flavor foundation of the entire beverage. Milk on the market falls into two categories: pasteurized fresh milk and ultra-high-temperature (UHT) sterilized shelf-stable milk, and the two differ noticeably in nutrition, mouthfeel, and shelf life. As for coffee beans, because a latte contains a large amount of fresh milk, the espresso needs sufficient body and fullness, making medium-dark or dark roasts more suitable. This article will go through the logic of choosing milk one by one, along with blend recommendations for different flavor orientations, to help enthusiasts find a milk coffee solution that suits them.
