Great tasting canned coffee
Really good can coffee. For a long time I used to get Jay Street coffee from Amazon but they stopped carrying it around a couple of years ago. Then I moved to UCC black coffee and they just recently stopped carrying that as well, so I just moved to BOSS black coffee. Great item that I’ve had during visits to Japan and happy to now get it delivered, but it is quite expensive ($41 for 12 cans, 8oz with a subscription as of this writing).

Perfect Taste. Even the Can is Top Quality
Can is thick aluminum. Taste is perfect. Made me miss Japan even more.

Hands down the best Cold brew on the market!
I have tried almost every other Cold Brew, this by far out beats them all, I never drank straight Black Coffee till I tried this, especially on a hot day and when your kind of thirsty, so refreshing and gives you a bit of a buzz! It doesn’t have a sour after taste like almost every other brand on the market! It’s enough come from Japanese craftsmanship!

Hubby LOVES this coffee
Bought them for my husband as part of his birthday request. He commutes by train, and this can size it perfect for his trips. In less than two weeks they were gone. He LOVES this coffee, says it is strong, brisk, and doesn't have a chemical aftertaste. We can only buy single cans at local Asian grocery stores, and the shelves are usually nearly empty, because it is a preferred and popular coffee brand.

Great flavor, bad price
I got hooked on these when I was visiting my friend in Japan. Anytime we would pass a vending machine, you could be certain Boss coffee would be there, and every time I was tempted. If you like canned coffee, then this stuff does not disappoint. I do want to note that if you are used to normal brewed coffee or iced drinks at your local Starbucks, maybe try some canned coffee before going in on this, as it's not cheap. Which brings me to my my gripe, this stuff is simply too expensive when you order it online. Yes, it's fantastic, but it's not $4 a can fantastic. Normally I purchase this stuff at my local Asian grocery store for ~$3 a can, sometimes less, and even then it's a bit of a splurge. Of course If you can't find it anywhere else, and you must have it, then by all means, treat yourself.

Authentic Japanese Coffee in a Can
When I drink coffee, I often want something quick. You can't beat coffee ready in a can! The truth is Boss coffee is a great coffee that takes its quality seriously. Without going into too much detail it's important to know the Japanese take taste and product quality very seriously. Of course you may see a few reviews about dented cans (they ship internationally it makes sense), but it really is important to talk about the taste and quality of this coffee. I drink a lot of coffee ranging from Mom and Pop shops to Starbucks, and I have to say the taste of Boss Coffee to be my favorite. I traveled to Japan a few times and daily my go-to has been small vending machine Boss Coffee. The taste is EXACTLY like what you would experience in Japan, which is nice because for a lot of people the accessibility to Boss Coffee outside of Japan is difficult. The black coffee itself is fresh, without tasting overpowered or over brewed. The convenience of grabbing it and going, adding it to any meal is nice as well. Small bonus to the Japanese writing on the top of the cans. Overall if you want to try something new I highly recommend trying Boss Coffee. I'm hoping we get a lot more flavors in the future!

nice flavor, nice branding
Ive been trying different cold coffee drinks and this is a solid choice, the taste is nice, slightly bitter with a nice smell and aftertaste so I would have to assume they use good quality coffee beans, definitely not bad for your basic no frills black coffee, although the price is steep the branding is novel, and what drew me to try this drink out. The 150mg of caffeine is a guaranteed boost, and Suntory was nice enough to send a thank you email that even said sorry about any dents, although in my case I couldn't detect any dents on any cans even though the packaging allows a lot of free movement, so for that they get all 5 stars from me
