I think the easiest way to discover all of these are to come and visit and hike!! There are already some guides about hiking, I suppose you would need to superimpose hike routes with wineries for each area you're interested in and make the hike work around the wineries. I am not sure this exists, as many wineries are spread out and connected with gravel roads but most people get around driving. There are some agencies that do this with bikes since it is faster to move around that way, so you might want to get inspiration from those routes!
