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.

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.

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…]
