As we first reported yesterday, Wirtz Beverage and McLane Company " owned by Warren Buffet" have formed a joint venture to acquire a stake in Missouri Beverage Company (MoBev). This is a big game changer for a number of reasons. First, it marks the fourth state and fourth wine and spirits distributor that Buffett has snapped up since he began with Empire Distributors in 2010. Secondly, this is Wirtz Beverage's first foray into Missouri.
