Temecula is the hot area they are cultivating.It’s much closer than napa. They estimate there are 20 million people living within 2 hours who would travel for tours and sales.
There is already a winery there, called Avensole but the biggest one won’t open until 2019

They are planning a hotel, luxury homes. It will be marketed both here and in China.

Might be a good area to invest. They have to employ lots of workers.
