Vending machines are on most corners of Japan, and it’s hard to run into one that’s not selling BOSS coffee - Japan’s #1 canned coffee brand. For those of you who drink black coffee (and don't we wish we all did), this is for you. This bold coffee blend features beans from Brazil, Ethiopia, and Colombia to create a rich flavor and smooth after taste. Zero sugar, 10 calories, and the caffeine equivalent of the double shot of espresso, this is the ultimate coffee boost for any slow morning.
