The beer business is buzzing over a potential mega-deal, after Anheuser-Busch InBev confirmed it has approached SABMiller's board of directors regarding a combination of the two companies, stating its intention to work with SABMiller's board "toward a recommended transaction."

The company's statement follows an earlier response to "press speculation" from SABMiller, in which it said it will "review and respond as appropriate to any proposal which might be made."
