Yet another reason why modern varieties of grapes are better than the old vinifera varieties

Napa is going to replant about 15% of the whole valley, due to the surprise inability of a rootstock (promoted 20 yrs ago by UC Davis) to withstand Red Blotch Disease.

Read about it here.

This is yet another reason why modern varieties (sometimes called "hybrids", with American grapes in their parentage) are better than vinifera. American grapes have evolved to keep up with the attacks by fungi and viruses, whereas for 2000+ years we have prevented vinifera grapes from evolving (by cutting and rooting them, instead of allowing them to make seeds, and then growing the seeds), so vinifera grapes have not been allowed to develop defenses against new microbe attackers.
