Around 2.25 billion cups of coffee are consumed worldwide every day, and with that comes a massive amount of spent coffee grounds. Traditional recycling methods—such as deodorizing, exfoliating, or making furniture—often require drying, which actually releases carbon dioxide.

This product, called COLEHA, not only contains three times the amino acids of green coffee beans, but its polyphenols and antioxidants also reach 1.6 times those of regular coffee, and it is rich in insoluble fiber that promotes gut health. COLEHA is currently available in limited quantities, with sugar content offered in three versions—0%, 10%, and 40%—each with its own distinctive taste. This article introduces this eco-friendly and innovative spent-coffee-ground utilization technology, along with the flavor and health secrets behind it. [more…]

When brewing pour-over coffee, should you really pre-wet the paper filter? This is a confusion many people encounter when they first get into pour-over. Some insist that wetting the filter is essential, while others brew directly with a dry filter. Which approach is actually more reasonable? The answer isn't absolute—it needs to be judged from three dimensions: how well the filter fits the dripper, the odor of the filter itself, and the storage environment. In addition, when wetting the filter, whether to use cold or hot water also matters—the choice of water temperature directly affects how well odors are removed and how well the equipment is preheated. Faced with the dazzling array of filter products on the market, the differences in flow rate and filtration effectiveness brought by different materials and manufacturing processes are huge. How should beginners choose?
