I don’t usually write about coffee — as I tend to make it home, where it’s easy to keep it keto friendly. I used to enjoy trying random drinks from the combinis in Japan, but after starting the ketogenic diet I found I could barely drink anything in Japan! Most of the drinks here are full of sugar, even those marketed as 低いカロリ (low calorie) or カロリオフ (calorie off).
For canned coffee, the only ones that are safe on keto are the “black” coffees. Typically this means Boss Black or UCC Black, which I’ve been able to find everywhere. Unfortunately, those drinks are not particularly nice! I find the iced coffee sold in the stores to be far better!
I spotted Ryusendo coffee a few months back in a Natural Lawsons. I didn’t buy it at the time (it was rather late), but remembered to pick up a can the next time I went.
This coffee is far, far better than the usual offerings from Boss or UCC. It is very drinkable! It’s not up to the standard of a good coffee shop, but it’s far better than anything else I’ve had from a combini.
It turns out Ryusendo is a town famous for some large caves and spring water. So, as you have probably guessed, this coffee is made with the aforementioned spring water.
My only worry, is that combinis are always changing their stock. I have found some nice products before, that disappeared after a few weeks. Still there’s always amazon.
So, if you spot this canned coffee whilst out and about in Japan — オススメ！
