Coffee roasting is far more than just applying heat; it subjects green beans to a series of dramatic transformations on both the physical and chemical levels. As the first article in this series, this piece focuses on the physical changes during roasting: from the color shifting from blue-green to brown, to the moisture content plummeting from 10-12% to about 2.5%, to the cell walls going from rigid to rubbery, the beans expanding in volume, porosity increasing, and oils migrating to the surface. These structural changes do not occur in isolation; they provide the necessary preconditions for chemical processes such as the Maillard reaction and caramelization. Only by understanding the physical changes can one truly grasp the relationship between the roasting curve and the final flavor. [more…]

Global food giant Nestlé has reportedly been working with investment bank Morgan Stanley on a strategic review of its high-end coffee chain brand Blue Bottle Coffee, with a sale being one of the core options. Sources say Nestlé may choose to sell the physical store network while retaining the brand's intellectual property.

After the pandemic, costs rose, and some cafés raised the price to 1.5 euros, which sparked consumer dissatisfaction.

If coffee at home has been sitting for a few months, is it still safe to drink? This is a question many coffee lovers run into. In fact, all coffee—whether whole beans or ground coffee—will eventually expire. Coffee is made up of degradable compounds such as carbohydrates, lipids, and amino acids, and over time it undergoes chemical and physical breakdown, changing in both quality and flavor. Roasters typically print a shelf life of about one year from the roast date on the packaging and use nitrogen-flushed sealed packaging to slow oxidation. However, once the bag is opened, the coffee gradually loses freshness as it is exposed to oxygen and moisture. This article will systematically address the safety of expired coffee, the factors behind its deterioration, how to tell whether it has gone bad, and how to extend its life as much as possible through proper storage and freezing while preserving the distinctive flavors of specialty coffee.

In recent years, animal-themed cafes have rapidly expanded around the world, with everything from cats and dogs to owls, meerkats, raccoons, and other wild animals being brought into the shops.
