Does anyone know where I can go to get good grapes? I'm in Iowa and around here it seems all I can get easily are the Minn grape varietals. I'm just getting started and would like to work with something a bit more familiar and maybe "easier". I'm not sure about the quality of the wines the Minn grapes are putting out being that I'm a big fan of big Cabs and dry whites. Anyone got any idea where I get grapes to make good wine?
