Coke bucket is characterized by cool and delicious coke, combined with strong jazz bourbon, which originated from the taste of cowboys in the western United States, creating a hearty and unrestrained pleasure. The alcohol content of Chu-Hi canned drinks is mostly between 3% and 8%, and it is a competitor of beer. The practice is to add a small amount of whisky and a large amount of coke, and cover up the taste of spirits with the taste of coke, which can be drunk by men, women and children. The continuous attempts of Japanese brewers such as Asahi, Takara and Suntory have increased the appeal of Chu-Hi, and they have introduced endless flavors, including yogurt, west Indian cherries and wild basil.
