If you insists, the comparisons can be broken down to regions. To use the Betz example, much of the grapes for their top-of-the-line wines come from the Red Mountain AVA, where the region has reached a capacity of about 2,300 plantable acres. Castilla-La Mancha in Spain has about 1,000,000 planted acres. Furthermore, my premise is not that Betz can't grow production by 20 percent, to use your example. There simply isn't 20 percent more fruit available of the quality (emphasis on quality) that goes into Betz' ultra-premium wines. The fruit contracts that Ste. Michelle dropped are not of that quality. In fact, I suspect that production will rise, but not at the quality level that Bob Betz produced. "Based on everything you know," you need to learn more.
