Rainbow mountain when?

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

Reading reviews and most interested in trying. I only drink hot coffee. Can I heat this coffee or is that a deal killer?

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!
