You might try googling something like "wine venture capital". Here is an article but seems more focused on online wine sales, http://www.internetnews.com/bus-news/article.php/156821
I would try that and contact a few venture capital firms that invest in wine startups. I did similar thing for a new concept I`m working on, Medivate www.medivate.com so I searched for "medical venture capital" and found a few med vc firms.
Good luck!
