I think it's a great start. I'm working on a related project. But one thing that may cause confusion is that at least in my mind, wines are related to wineries or producers, and through a winery to one or more vineyards, rather than directly to vineyards. Often a winery is also a vineyard, but at least with cult wines there's a symbiotic supplier relationship, wherein, for example, a winemaker will produce a wine made from grapes grown by a particular vineyard, which is owned by someone else. The winemaker will then "vineyard designate" the wine, to both the winery's and the vineyard's benefit. So the quick fix is that I think from looking at what you've built here, that maybe you should have a big list of wines, and another big list of wineries, rather than vineyards? Hope this helps :)
