By mixing the coffee extract extracted in 30-65 u2103 warm water with the dry coffee extract with the absorbance value of less than 0.8 at 680nm wavelength per 1% weight of the soluble solids when diluted with water, and then putting it into a container, the storage stability of the coffee extract can be ensured at the same time, and the coffee beverage with the original flavor of the coffee can be produced. It's better for sugar free coffee drinks (black coffee) and hot drinks.藉由使以30~65℃之溫水所萃取之咖啡萃取液，與具有於用水稀釋時在可溶性固形份每1重量%之680nm波長之吸光度為0.8以下之值之乾燥咖啡萃取物混合後裝入容器中，可同時確保其保存安定性，且製造可品嚐咖啡本來風味之裝於容器之咖啡飲料。適用於無糖的咖啡飲料為佳(黑咖啡)，適用於熱的飲料也為佳。
