Ready-to-drink coffee comes from Japan, where the world's first can of ready-to-drink coffee was born. In a country where coffee culture is everywhere, vending machines full of ready-to-drink coffee are everywhere – according to the Japan Coffee Association, 2.2 cans of 11 cups of coffee per capita per week in Japan are ready-to-drink coffee, and the average person consumes 100 cans of ready-to-drink coffee per year. The reason why ready-to-drink coffee occupies such an important position in Japan is mainly due to its convenience and affordable price, and UCC's canned coffee is a permanent product of tens of thousands of vending machines and convenience stores in Japan, and the overall taste is above the horizontal line.
 
Founded in 1933 as Uejima Shoten, UCC produced the world's first bottle of ready-to-drink coffee as a retail item in 1969 and is recognized as Japan's national coffee brand. UCC is the abbreviation of Ueshima Coffee Company, which is now not only a coffee beverage manufacturer, but also has a chain of coffee shops on Ueshima and has its own coffee estates in Jamaica and Indonesia. UCC has strict quality standards, green beans are subject to strict quality inspection by coffee appraisers before entering the factory, and its canned coffee factory is HACCP certified.
 
The raw materials of UCC coffee are produced in Vietnam or Brazil, which are the largest exporters of Robusta beans. Robusta beans are widely used in commercial coffee beans, with less pronounced aroma and sourness, more bitter taste, richer oils, and twice as much caffeine than Arabica beans.

If you want to pursue a pure and mellow taste, UCC's sugar-free black coffee is very worth trying, the main ingredients are only water and coffee, the sour and bitter are more balanced, there is no miscellaneous taste, with an aftertaste, and at the same time, it is relatively smooth to drink, and it is easy to accept for people who do not drink black coffee often.
