Many wine geeks spend all their free time on Wine Berserkers, a wine discussion board that was launched in 2008 after Todd French, an oenophile in San Clemente, was kicked off Robert Parker’s e-bulletin board. Today, Wine Berserkers is world’s most active wine board. It boasts nearly 20,000 members and receives nearly 9,000 visitors each day.

Tomorrow, Wine Berserkers is expecting to receive more traffic than ever before. The reason? BerserkerDay.

Every year, French invites wineries, retailers, and others to offer “berserk” deals. These deals are posted throughout the day — and many are absolutely unreal. It’s completely free — retailers don’t pay to participate, and this year, BerserkerDay is open to the public. You don’t even have to be registered on Wine Berserkers. (That said, paying members can preview the deals today!)

As French explains, “this day of deals is a fantastic way for those ITB to give back to consumers, and also the reverse, as many, many new and exciting wineries/producers/wines are discovered by Berserkers on BerserkerDay, with purchases made, and discussions from those who might have experience with them.”

So check it out. And make sure your credit card is ready for some serious damage!
