The professor also noted that sweetness in aroma is appreciated: "That is why several people like the Hansen Riesling-Semillon." That vintage smells like a harvest wine but is dry, Boyce notes. Personally, I thought the nose was divine but the taste had me reaching for the spittoon. (Full disclosure: I had a slight head cold, so my sensory perceptions were a bit off all night.)

You can check out the scores and comments bottle by bottle on Grapewallofchina.com, me highlights:

Of the 16 wines priced at 150 yuan or less, only four got more "dislike/hate" votes than "love/likes".

The most likes/loves went to Grace Chardonnay with 11 votes (11 likes). The runners-up, with 10 votes each, were Grace "Premium" Chardonnay (four loves, six likes) and Helan Mountain "Premium" Cabernet Sauvignon (one love, nine likes).

The number of quality wines from China impressed the tasters. "The Chinese were proud of these Chinese wines and said they could buy the ones they 'love'," Ma says, "even though they might be more expensive and less intense than imported ones."

The consumers on the panel almost all said they enjoyed the first flight of whites better than the comparably priced first flight of reds - even though reds command the lion's share of the market in China. Looking at the scores, Boyce notes: "There was a much bigger range between top and bottom for the white wines, with consumers finding the white wines easier to distinguish and the red wines more homogenous."

Boyce also points out that in the final flight, the pricier wines, almost every judge liked or loved both of the chardonnays on offer, though they were very different. "Out of 13 votes, oaky Grace Tasya's Reserve received five 'loves' and seven 'likes', while fruitier Helan Mountain Special Reserve received five 'loves' and eight 'likes'.

"This shouldn't be a shocker," Boyce says on his blog, "but the point is often lost because it is far easier to generalize about a billion-plus people and seek a single solution - or a single kind of wine - than to deal with the complexity of the China market."

What did I learn, besides not to drink a lot of wine with a head cold?

That Hansen, Helan Mountain and Silver Heights are Chinese labels that now deserve to be mentioned in the same breath with Grace. That Ningxia may be the place I want to retire. And that Great River Hill winery in Shandong, home of Chateau Nine Peaks Cabernet Sauvignon 2011, is bucking the conventional wisdom that says China's best wines are now rooted in the western regions.
