冷凍乾燥咖啡是如何製作的？
Freeze-dried coffee is made by brewing ground coffee beans with water, evaporating some as much of the water as possible to leave behind a coffee extract, which is then frozen and broken up into soluble instant coffee granules.
冷凍乾燥咖啡是通過用水沖泡磨碎的咖啡豆製成的，盡可能多地蒸發一些水以留下咖啡提取物，然後將其冷凍並分解成可溶的即溶咖啡顆粒。
