As for that other vital ingredient, rice wine, in the past King Duck always used "red label" rice wine, a long-time staple of local cooking. Each duck was divided into five servings, and they used one bottle of red label (about 600 cc) per serving, or five bottles of rice wine for each bird.
至於另一個重要材料「米酒」，過去帝王薑母鴨都使用紅標米酒，一隻鴨子分為五份，每一份使用一瓶米酒，也就是一隻鴨子要用上五瓶酒。
