Q

Rain?
Humidity?
Vineyard planting?

A

Coast Beijing and Hebei have a humid continental climate, warm humid summers and cold winters plus torrential rain in August/Sept.
20-30 cm of rain a year, cool pacific breezes reduce final disease, but still a challenge.
Older vineyards planted on flat land, poor drainage and fertile soil = hi yields poor fruit,
Newer vineyards on better sites
Closer to ocean don’t need burying, saving cost
