## 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

*by K***N on October 14, 2025*

Perfect shot of espresso. It’s as if I was at a 7-11 in Japan again. Caffeine content and taste is worth the money. Its mini size is perfect to fit into my pocket when I’m running out of the house too.
