I lived in Shanghai for 18 months, ten years ago. The beer was mostly horrific. Even as someone that was used to Aussie megaswills, it was bad.
I did taste Tsingtao in Qingdao though, during their version of Oktoberfest, and it was nothing like the bottled headache that is Tsingtao everywhere else. It was a genuinely nice, German style beer. Very weird drinking it on the beach, from a plastic bag with a straw out of it, but hey - you have to immerse yourself in the culture. I just wish I got a photo cos no one really believes me when I tell that story.
Once the pandemic is over, will your bar see a western expat crowd? That would maybe dictate a change in your beer selection.
What is the Chinese drinking habit like at your bar? A custom while drinking midstrength out of small glasses over dinner is to finish glasses together. "Kampei" (whatever the pinyin spelling is, sorry for butchering it) is basically cheers + bottoms up. I saw a table of people doing that with red wine, and it ended with vomit in a hotpot.
I'm asking because if people are drinking like that in your bar out of larger glasses, you might need to stock a selection of 3% abv beers...
