I think this is a great idea. I would love to see wine grapes added, similar to the arborist. Possibly even a blend of arborist and farmer, where you could plant them, adjust soil through sand and clay to get a perfect blend, and harvest seasonally, just like the arborist does between apples, pears, and peaches. A vintner would add an additional use for barrels and glass, as mentioned, but wine could also provide a way for upgrading a pub. Just some additional thoughts, but thanks for the great suggestion.
Cheers
