Went to a business meeting the first time I came to China, they opened a bottle of 500 USD bottle of wine.

One guy put cola in the wine.
One guy put a cube of sugar.
Another just chugged his.

Then they mocked me for wanting to let the wine breath and kept trying to fill the glass to the brim.

Things are slowly changing - these days more and more people understand. Its the new rich that does this because they are supposed to like wine because the "cultured" drink wine.

I always cringe because the local wine stores do not have refrigeration and keep full bottles by the window in direct sunlight. The inside of their stores are 30 plus degrees Celsius in the summer and frigid in the winter.

Wine culture has a long way to go here in a third tier city in China but it is improving.
