Hello Mark C. Thank you for taking the trouble of posting a reply. As a child, I remember my parents had a grapevine with everything inside the greenhouse, except the root which went through the wall and planted outside.
I do agree that wine growers want natural light, natural heat and natural rain. So does much of the rest of society. For example, I don’t care for battery-reared chickens. Vegetables, including fruit, taste better if grown outside. As Inbar says, wine is a luxury product. Its manufacture could be construed, by some, as an extravagance.
Whilst urbanisation is unstoppable, I still prefer green fields to motorways.
