I stumbled upon a website http://www.planetgreen.com/ I've literally been surfing for HOURS. There is so much information here!
I've learned a lot of interesting facts, but I think the number 1 thing I've learned is that MOST wines are not vegan! (my heart skips a beat )
During the filtration process a lot of wine makers can use animal based products to fine tune their wine's taste. Such as.... egg albumen, gelatin, isinglass, and bone marrow. ( ......Woof) Granted they only use these ingredients in minute amounts, I figured I would share a couple of vineyards that create vegan and organic VINO.

http://www.ourdailyred.com/ - Make a great organic, sulfate free, vegan wine called Our Daily Red.
More to come as I taste :)
