Wine grape season begins by digging up vines

Unearthing vines requires careful observation and weather judgment, said Gao Yuan, an experienced winemaker. Unusual cold spells in early spring might occur in Ningxia, so it is necessary to dig a few vines and observe their conditions before large scale unearthing, she added.

Ding Jian, owner of a winery in Ningxia, has nearly 200 workers busy with planting.

The weather is full of uncertainties, and so is the wine. That is the charm of wine, Ding said.
