As I mention in the about page, currently there are only 2 Kosher Wine Blogs I recommend – both are great:

•  Yossie’s Corkboard by Yossie Horwitz
•  Kosher Wine Musings by David Raccah

Additionally there are 2 excellent pages on Facebook that are worth following:

• Kosher Wines: Sharing & Experiences (English)
• Vin Casher: Partage, Bons Plans et Conseils (French)

Both are administered by Gabriel Geller, currently the Director of Public Relations & Communications at Royal Wine Corp, and in addition to David & Yossie referenced above, one of the most knowledgeable people around about Kosher Wine. While Gabriel works for Royal the Facebook pages themselves have nothing to do with Royal at all and Gabriel’s opinions are IMHO objective.
