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 M***N on October 27, 2024* ### ⭐⭐⭐⭐⭐ Review *by O***A on December 2, 2025* ### ⭐⭐⭐⭐⭐ Review *by N***O on November 29, 2025* ## Frequently Bought Together - 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 - BOSS Coffee by Suntory - Japanese Flash Brew Coffee with Milk, 8oz 12 Pack, Imported from Japan, Au Lait, Espresso Doubleshot, Ready to Drink, Contains Milk, No Gluten - 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 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/261470706-rainbow-mountain](https://www.desertcart.sn/products/261470706-rainbow-mountain) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-17*
