I was just researching Weingut Hans Barth and found that they, along with other Weinguten, have some kind of vineyard sponsorship or "time-share" program going on. The program is called "Ihr Rebestock" and it speaks of one wanting a vineyard but knowing nothing about caring for one. Thereby, you can buy a vine for 10 years, they supply the "care" and you get one bottle a year from their "contractor house".
Is this for real??
