    “

    Decaffeination doesn't just remove things; it rebalances them. It’s about using a 'hook' specifically shaped to grab caffeine molecules while letting the flavor compounds stay put, ensuring you don't wash away the soul of the coffee.

    자주 묻는 질문

    The decaffeination process involves removing caffeine from green coffee beans before they are roasted. This is typically achieved through various methods such as the Swiss Water Process, solvent-based extraction, or carbon dioxide treatments. Each technique aims to strip the caffeine molecules while preserving the essential oils and flavor compounds that give coffee its distinct taste and aroma.

    The Swiss Water Process is a chemical-free decaffeination method that relies on osmosis and solubility to remove caffeine. Green coffee beans are soaked in hot water to extract caffeine and flavor solids, then passed through a carbon filter that traps only the caffeine. The resulting flavor-rich liquid is used to treat new batches of beans, ensuring a high-quality decaf coffee without the use of harsh chemicals.

    While the goal of caffeine removal is to eliminate as much as possible, most decaf coffee still contains a trace amount of caffeine. International standards generally require that at least 97% of the caffeine be removed for a product to be labeled as decaf. This means that while it is significantly lower than regular coffee, it is not always 100% caffeine-free depending on the specific method used.
