## Description

WELCOME TO SOMETHING NEW Introducing, for the first time in wide release across the United States, a major Japanese ready to drink coffee brand BOSS COFFEE. 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: Really good can coffee. For a long time I used to get Jay Street coffee from desertcart but they stopped carrying it around a couple of years ago. Then I moved to UCC black coffee and they just recently stopped carrying that as well, so I just moved to BOSS black coffee. Great item that I’ve had during visits to Japan and happy to now get it delivered, but it is quite expensive ($41 for 12 cans, 8oz with a subscription as of this writing).
Review: Too expensive for 12 cans

## Questions & Answers

**Q: Rainbow mountain when?**
A: We are so glad you like Rainbow Mountain Blend in Japan! 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!
