Yup! They can't afford to nuke the plants with chemicals or buy big machinery so they selfishly pretend they want sustainability for their children rather than going for a quick buck with a sterile prairie. Bastards!
There is a hand-picked/machine picked debate though. Machine picking on a big scale requires vines selected and grown for uniformity rather than quality. It is pretty brutal and the machines compact the soil which means more chemical fertiliser is required. They also tend to damage and squash the grapes so they start oxidising and fermenting on their way to the winery. There is no selection, everything is torn off together. The plus side is that the grapes can be picked quicky at the optimum time and in the cool of the night.
Can you see the driver? He's the tiny thing near the top on the left. This beast prunes, sprays and picks.
Hand-picking is slow and labour intensive. You can be delicate and selective though. Using small baskets and cool storage the grapes remain in perfect condition. The richer estates have teams of expert pickers on stand-by until conditions are perfect. If you want to select individual grapes for an eye-wateringly expensive wine there is no option. You don't need to nuke the grapes with anti-oxidants.
It is the difference between soul-less mass-production and passionate craft.
