Wow. Where do I even begin?
Let me take you back to October of 2017. I had made my first trip to the wonderful land of Japan and nestled in among the good people who live there. During my stop in Kyushu, I ran across this BOSS Rainbow Mountain Blend coffee at an AEON Mall. At the behest of my friend who I was staying with at the time, I bought some to consume on the spot. It was already chilled, and as soon as the coffee hit my taste buds, I was in for a real treat. I was sure to buy up some more to take home with me on the flight back to America. Don't let the 6 oz size fool you. These little coffees pack a wallop and the taste is phenomenal. Even though I'm not one to get cream or sugar in my coffee (as Brian Griffin says, I like mine black as sin), the combo of everything feels just right. The quality of the roast is quite solid. Consisting of slightly woody notes, with not a sign of burnt flavor, this should appease any coffee snob anywhere. I'm so glad Suntory finally came to their senses and started properly importing this stateside for our enjoyment. The price is certainly higher than your typical Starbucks brew, but this really is a unique experience, almost a rite of passage that everyone should go through, and a good taste of what the Japanese like to call quality coffee. This beverage gets my seal of approval. Even if you find the price a bit too high, I'd still consider getting one case for the novelty factor and, who knows, maybe you'll get hooked? :)

Delish! Worth Every Penny, No Doubt!
Not quite as pristine as the black but still so yummy. They call it BOSS for good reasonโฆ it leads head and shoulders above the rest! Slightly smokey, clean and smooth. Perfect pick me up treat in the afternoon. I regret nothing!

Refilled my HEAT gauge.
Bought this as a fan of Yakuza, got made a fan of BOSS coffee. Genuinely, insanely good coffee that beats the hell out of Starbucks RTD's which by my estimation, are far more concerned with sugar than coffee. 110mg of caffeine per can means you're getting a kick without blowing your heart valves and the modest size means you can easily put down a can in its entirety in a sitting, as well as it being convenient for travel. I wish this was cheaper or more readily available, I would drink this regularly if I could.

Great product but the price hurts the wallet
I love these coffees a lot. I like to buy a case to keep on hand for the days that I'm feeling sluggish or having a hard time rolling out of bed since they give more caffeine than a 20oz soda at a literal fraction of the calories. I'd make them a part of my daily routine if not for the fact they run so expensive. At $45 for a case of 12 it's just not viable for every day drinking.

Intensity and flavor
As my title states, this coffee has an intense yet balanced flavor. I enjoy the caffeine strength
