So just to start out the bottle I have of this is pretty well aged, so my review is only going from that, I'm not sure what this tastes like fresh.
As others have mentioned, this is a very unique flavor. I've never had Kuri Kinton nor have I ever even heard of it. Apparently it uses a certain kind of Japanese sweet potato that is sweeter than what I'm used to. I'm not a fan of sweet potato, but KiC typically does quality work so I was certainly intrigued by this.
I will say I appreciate new and unique flavors, I can't say I've seen anyone else even attempt a flavor like this before. Does it succeed? I certainly think so. I was surprised that I wasn't really getting the starchy sweet potato as others have mentioned, at least not like I was expecting. There certainly is a slight starchiness there, but in a blind taste test I'd be curious who would guess it was a sweet potato.
The berry syrup and candied chestnuts come next and blend together very well, and wrap the profile up nicely. I'm honestly not sure what the berry would be, to me it's not a blackberry, maybe a strawberry/blueberry mix? Dash of cherry? Everything in this mixes so well it's hard to pick out, but it does provide an overall enjoyable experience. The candied chestnuts are not overpowering, you certainly don't walk away describing this as a nutty juice overall. It's there, but when you consider extra-sweet sweet potatoes, berry syrup, and candied chestnuts, you do mostly get a sweet / dessert style vibe more than anything. It certainly isn't too sweet by any means, very enjoyable.
My biggest critique here is the mouth-feel, it definitely has a lighter mouth feel and I prefer a thicker. It doesn't have a lot of body to it, it vapes kind of thin for my tastes. It vapes extremely smooth yet is slightly dry on the exhale, but not bad. I didn't detect any throat hit.
So for me personally I'm not sure I'd re-order this one, though I still respect what they are doing here. I don't think anyone would be displeased with this juice, and if you like lighter flavors this one would definitely fit the bill. I'd give the intensity about a 4 or 5 out of 10. It's got decent flavor, but I think just a bump in overall intensity would make this one pop a lot more.
It's mixed well, and is very unique and I appreciated the experience of trying something different.
