More and more alcohol in Californian Napa Valley wines - too much?

Average Napa valley Cabernet Sauvignon alcohol levels 1976 - 2016

Average alcohol levels in California's Napa Valley Cabernet Sauvignon has risen from 13.6% in 1976 to 15.4% in 2016. Not great if you're concerned about the amount of alcohol that you consume when you drink wine. The reasons - changes in the Californian climate, later picking and hence riper and hence more alcoholic grapes and finally changes in vineyard practices.
