Dr. Joe Fiola sent out a notice about this new cooperative winery in Maryland (http://www.portofleonardtown.com/about.cfm).  It is an interesting concept, one that OSU researchers have explored before.  You can read all about winery cooperatives here in paper by Dr. Phil Kenkel and Dr. Rodney Holcomb, both of OSU:http://www.agecon.ksu.edu/ACCC/ncera210/Events/2006meeting/Winery06.pdf.  Both authors also contributed a chapter in our new Handbook of Oklahoma Vineyard Establishment and Management, available here: https://secure.touchnet.com/C20271_ustores/web/product_detail.jsp?PRODUCTID=776
