Beer connoisseurs know that that Belgian sours are renowned for their intentionally tart or sour taste that has taken beer to a whole new level. The acidic yet flavorful mouth feel often inspires drinkers to think of Champagne. But just how sour is sour? Global Beer Network, the exclusive U.S. importer for more than 60 Belgian beers, has launched the Sour Power Pack that features a six-pack of Petrus beers that users can mix and match to create the ultimate blend.

"Sour beer fanatics love to experiment, so we've created the Sour Power Pack to provide the best beers for custom blending for those who want to create new sour combinations," said Steve Villani, president of Global Beer Network. "These Petrus sours are savored worldwide and are delicious alone or with a meal. But when you mix these beers in various amounts, you can alter the taste dramatically. When it comes to sours, everyone loves something different and the Sour Power Pack even includes a blending chart to help users create the perfect tasting."
