If the deal goes through, the new company would control commanding market shares in much of the world. So how big are Grolsch and Peroni, the two SABMiller beers that could be sold?
They're major brands in their home countries of the Netherlands and Italy, respectively, but relatively small parts of the SABMiller empire. Together, the two breweries produced about 6 million hectoliters of beer last year, according to company documents. That's about 2.5 percent of SABMiller's 2014 production and 1 percent of production by the two giants combined.
