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. Review: Great flavored coffee even for us coffee snobs!!! Absolutely love this product!!!! - Fabulous tasting coffee! Great seller!! I am a bit of a coffee snob and I really love the flavor of this coffee! I have to be at work by 5:00 AM and this product gives me a perfect jolt of caffeine to get me off to an early morning start! I could not be more pleased and will continue to be a returning customer! Thank you so much!!! ## Features - NO.1 CANNED COFFEE BRAND IN JAPAN – BOSS Coffee is the No.1 canned coffee brand in Japan (2021, Intage). Beans sourced from the best Brazilian grow regions are brewed and canned in Japan by Award Winning company, Suntory - the makers of the No.1 bourbon (Jim Beam) and other fine whiskies. - READY TO DRINK COFFEE – For the on-the-go professional who demands high quality coffee. Enjoy when you rise, in a mug or straight out the can. Enjoy your way - in travel or pour over ice, to create a crisp iced coffee. - MEET THE NEW FLASH BREW – Temperature is high when we brew then chilled rapidly to create an authentic 'flash brew' coffee. This allows for a bolder flavor with a smoother aftertaste without negative bitterness. - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PMNR4FR | | Best Sellers Rank | #21,922 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #27 in Ready to Drink Liquid Coffee | | Brand | BOSS | | Brand Name | BOSS | | Caffeine Content Description | Caffeinated | | Caffeine Content Per Serving | 140 milligrams | | Coffee Blend Name | BOSS | | Coffee Roast Level | Dark Roast | | Coffee Type | Prepared Coffee Drink | | Container Type | Can | | Customer Reviews | 4.6 out of 5 stars 829 Reviews | | Diet Type | Vegan, Vegetarian | | Each Unit Count | 12 | | Flavor | Black | | Item Dimensions | 2.08 x 2.08 x 5.23 inches | | Item Form | Liquid | | Item Package Weight | 3.54 kg | | Item Volume | 96 fluid ounces | | Item Weight | 8 ounces | | Manufacturer | Suntory B&F N.A. | | Number of Items | 12 | | Number of Pieces | 12 | | Package Information | Can | | Roast Level | Dark Roast | | Size | 8 Fl Oz (Pack of 12) | | Special Ingredients | Keto Friendly, Sugar Free | | Specialty | Flash Brew | | Sweetness Description | Not Sweet | | UPC | 088857019765 | | Unit Count | 96 Fluid Ounces | | Variety | Flash Brew Original Black Coffee, Espresso Doubleshot | ## Product Details - **Brand:** BOSS - **Caffeine Content Description:** Caffeinated - **Flavor:** Black - **Item Form:** Liquid - **Roast Level:** Dark Roast ## Images ![BOSS Coffee by Suntory - Japanese Flash Brew Original Black Coffee, 8oz 12 Pack, Imported from Japan, Espresso Doubleshot, Ready to Drink, Keto Friendly, Vegan, No Sugar, No Dairy - Image 1](https://m.media-amazon.com/images/I/71hHVFDGpsL.jpg) ## 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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must have for my Japanese husband *by M***Y on April 6, 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.
