About This

NO.1 CANNED COFFEE BRAND IN JAPAN - Conveniently found in vending machines and convenience stores across the country, Suntory has innovated BOSS Coffee for over 30 years to become the no.1 canned coffee brand in Japan (2021, Intage).
RAINBOW MOUNTAIN BLEND - Using beans sourced from seven grow regions managed by Guatemalan Coffee Association farmers, Suntory’s expert brewers blend the unique flavors produced in diverse climates to create our signature Rainbow Mountain Blend.
STRAIGHT FROM JAPAN - Due to popular demand from BOSS fans, we are delighted to bring Rainbow Mountain Blend, with the same great packaging and flavor as in Japan, to the US market. Enjoy an authentic taste of Japanese coffee culture.
READY TO DRINK COFFEE - Rainbow Mountain's 6 fl.oz can is perfect to slip into a pocket or bag and take on-the-go for a high quality coffee pick-me-up anytime, anywhere.
NATURALLY BREWED CAFFEINE - With only 70 calories and 110mg of naturally brewed caffeine, don't underestimate this handy can size. Rainbow Mountain Blend packs the equivalent of a doubleshot of espresso in every can, more than enough to get you going.
