BOSS Coffee delivers flavor and quality, without the negative bitterness using the coveted flash brewed coffee method. Essentially, we're brewed different. WELCOME TO FLASH BREW Using a traditional and proven process from Japan, we have perfected the method to create the most ideal cold coffee on the market today. We know that true coffee flavor can only arise from beans when brewed at “hot” temperatures. That is why we brew our coffee piping hot and chill it in a “flash” - resulting in cold coffee without sacrificing the better elements of hot. A FINE SUNTORY BEVERAGE BOSS Coffee started its history in 1992 in Japan. We have honed our expertise in Ready-To-Drink (RTD) Coffee from coffee beans to our final products, with continued efforts to improve every aspect of our process and pursue the best quality RTD coffee can offer. BOSS Coffee is made by a Japanese company called Suntory - you may know of them as Beam Suntory (the makers of Yamazaki and Jim Beam whiskey). Imported from Japan in US packaging. Review: Too expensive for 12 cans Review: When I first started dating this Japanese guy I knew (wink, wink) , years and years go, it was hard to find Japanese-brand-specific products in the US, online or in “Asian” stores. It’s amazing how much more global the world is becoming and how products are becoming more available everywhere. Now we can obtain so many great Japanese products in the US. I’m not a coffee drinker, nor am I Japanese, but even I know the significance of BOSS Coffee. However, my husband is addicted to coffee. I surprised my Japanese husband (who’s been living in the US over half his life) with this pack for his birthday and cannot describe the type of positive impact it had on him. There’s just something special about this coffee and I get it. I try to keep him stocked up on this product, but out of the canned coffees we’ve ordered, this one is the most expensive. Maybe because it’s coming straight from Japan? And we started ordering this regularly summer of 2025. We tend to go for other brands more often because of price. But still, there is something special about BOSS. It’s almost like “umami” - the unique mixture of a strong flavor, ubiquitous Japanese culture, hot summers in Japan, buying coffee from vending machines, getting a boost to get over the jet lag, etc. The mix of memories, mental notes and taste, whipped up into one can of BOSS Coffee. ## Features - COFFEE, THE ORIGINAL ENERGY DRINK – Leave sugar-filled beverages and soft drinks behind. Boss coffee is a great alternative to nitro cold brew coffee and sodas. - LOW CALORIE NATURALLY BREWED CAFFEINE – Only 10 calories per can, 0 grams of sugar, and 140mg of naturally brewed caffeine - the equivalent of a doubleshot of espresso. - Boss COFFEE by Suntory - Japanese Coffee Drink - Imported Coffee - Flash Brewed - Gluten Free, Sugar Free, Dairy Free, Keto, Vegan.

We are so excited by the number of customers who already know BOSS and can't wait to bring new flavors. While Rainbow Mountain is not currently slated for release in the US this year, we ARE releasing another flavor in summer 2019 and hope to add more as we see demand in the US. Please be sure to follow us and in the meantime try our great Black or Au Lait flavors. We have pushed your feedback to the team so they are informed on flavors our customers want. Thank you once again, Suntory **Q: Does this contain caffiene?** A: Yes, it does contain caffeine. **Q: When will it be back in stock?? please!** A: call amazon **Q: Reading reviews and most interested in trying. I only drink hot coffee. Can I heat this coffee or is that a deal killer?** A: Thank you for your interest in BOSS coffee! We highly recommend drinking BOSS coffee chilled for the best experience. The can should never be placed in a microwave as it is dangerous to do so, but it is possible to heat the liquid after pouring into a mug. We hope you will enjoy BOSS coffee your way, hot or cold! ## Customer Reviews ### ⭐⭐ Review *by N***N on 30 October 2025* Too expensive for 12 cans ### ⭐⭐⭐⭐⭐ Review *by M***Y on 6 April 2026* When I first started dating this Japanese guy I knew (wink, wink) , years and years go, it was hard to find Japanese-brand-specific products in the US, online or in “Asian” stores.
