This stuff is dangerous.
This is the very first can I ever tried, a couple weeks ago. I haven't had it since, though I haven't exactly sworn it off. Chu-hi is basically a wine cooler, though Japan has those too. Zima is on the shelves of my local convenience stores. But being a locally-made product, it's cheaper.
If you've ever had a wine cooler, you basically know what this tastes like and how the experience will go. I've found that wine coolers taste okay, but soon after I don't feel so good. This had the same effect. I am sure part of the issue is how fast I could drink this compared to beer, plus possibly having an empty stomach.
I know a few friends in Japan who are essentially addicted to chu-hi, and at a price that's comparable to or cheaper than beer, I'm not surprised!
Personally, when I do drink in Japan it's usually beer. I finally bought a bottle of Jack Daniels to make some Jack and Cokes from time to time. What's your poison of choice?
