Being in China I determined to drink mostly Chinese wines until I know their basics. There are none available in my home country. Much more expensive European wines are coming into vogue at Chinese dinner parties, mostly basic Bordeaux AOC, and I found there are reasonably priced Chinese wines that compare well. There are also apparent fake French wine (suspected by taste and label gaffes).
My experience with Chinese wine is generally good. However, sometimes the same bottle in different shops can be different (possibly transport and storage positions and lengths and temp. conditions?). The vintage year is in fine font along with other coded info on the neck of the bottle, its rarely on the label. Sometimes a 2016 and a 2013 bottle can be stocked side-by-side at the same price.
One of the unexpected highlights is from Great Wall, a 2016 Pengli County, Shandong Province white wine (bai putao jiu) of the "3S" series (around 65 RMB at Tesco). See label pic on Great wall website.
Any other aficionados who care to give experience of Chinese wines under 200 kuai RMB that are currently readily available in Chinese stores?
