The world would be a better place if this were more widely available and in every flavor like in Japan. Great pick me up. Delicious flavor. Great hot, cold, or room temp. Japan spoiled me with these and now I'm obsessed. Review: Was never a coffee person until I went to Japan. I’ve tried Starbucks, Dunkin, local coffee houses near me, and sure I like a hot chocolate every now and then, but never could I get into coffee. The bitterness was always too much. But then I went to Japan, and tried this canned coffee at the recommendation of a friend who bought it at FamilyMart on a whim. Immediately, my life transformed before my very eyes. I became buff. Women threw themselves at me. All of my problems solved themselves. I got my dream job. I became rich. I was no longer mentally ill. And most importantly of all, I found a coffee I actually liked. It’s got just the right blend of sweet and bitter that doesn’t make me want to spit it out immediately. I love this coffee so much I make a 6oz can last 2-3 hours. Any quicker would be sacrilege. It’s a shame it costs so much money but the financial burden is worth it to me, because it’s a nice little treat in the morning which also helps curb my body’s apparent constant need for sugar (only 20% DV? Crazy!!). Don’t go for that crappy canned Starbucks you see at convenience stores, go the extra mile and get BOSS coffee, because it will change your life like it did mine. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08L4KNBV6 | | ASIN | B08L4KNBV6 | | Brand Name | BOSS | | Caffeine Content Description | Caffeinated | | Coffee Roast Level | Light Roast | | Container Type | Bag | | Customer Reviews | 4.6 4.6 out of 5 stars (1,045) | | Customer reviews | 4.6 4.6 out of 5 stars (1,045) | | Diet Type | Gluten Free | | Flavor | Coffee with milk and sugar | | Item Dimensions | 5.3 x 5.3 x 10.5 centimeters | | Item Form | Liquid | | Item Package Weight | 2.77 Kilograms | | Item Volume | 2128.8 Milliliters | | Item Weight | 170 g | | Product Dimensions | 5.28 x 5.28 x 10.49 cm; 170.1 g | | Special Ingredients | Milk, Sugar | | Sweetness Description | sweet | | UPC | 088857019949 | | Unit Count | 72.0 Fluid Ounces | ## Product Details - **Brand:** BOSS - **Caffeine Content Description:** Caffeinated - **Flavour:** Coffee with milk and sugar - **Item form:** Liquid - **Roasting level:** Light Roast ## Images ![BOSS Coffee by Suntory - Rainbow Mountain Blend Japanese Flash Brew Coffee, 6oz 12 Pack, Imported from Japan, Espresso Doubleshot, Ready to Drink, Contains Milk, No Gluten - Image 1](https://m.media-amazon.com/images/I/819RtFl76DL.jpg) ## Questions & Answers **Q: Anyone know if this is actually brewed and canned in japan, or is it just the recipe from japan and canned in the us?** A: Thank you for your interest in BOSS coffee. All BOSS US products (At Cafe Au Lait, Rainbow Mountain and Black) are brewed and canned in japan. They are all exported from Japan. We hope you will enjoy BOSS coffee! **Q: Do these need to or can be refrigerated?** A: They do not have to be refrigerated . They taste better hot or cold. I prefer cold. **Q: Anyone know why only the coffee is sold and not the tea? Tried contacting seller but no luck so posting here in hopes for a reply.** A: Probably gauging interest in the brand. If you’re in the US, coffee is universally more consumed than tea (I prefer tea). The coffee being available online is relatively new. They also must be experiencing difficulties in the warehouse as there are tons of cans that will arrive dented and damaged while the outer box looks untouched. This appears to be an issue with how the individual cans are packaged as opposed to Amazon delivery methods. So TLDR: give it some time and they might bring tea as well **Q: Once empty, can these cans be crushed?** A: If you put enough force into it then yeah, they should be crushable ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by O***A on 2 December 2025* Fantastic coffee!
