A $107 billion bid by the world’s biggest beer company, Anheuser-Busch InBev, to buy the world’s second-biggest beer company, SABMiller, received the federal government’s blessing last week. The question now is whether American beer lovers ought to be concerned. And the answer is unsatisfying: nobody’s sure yet. While a can of Bud will likely cost about the same next summer as it does today, beer insiders say the real impact of this acquisition—nicknamed the Megabrew deal on Wall Street—on the robust American industry could come in the form of fewer locally-owned breweries, and therefore fewer consumer choices: fewer craft brews, fewer imports, and less innovation on tasty new products. Whether the industry goes in that direction won’t be clear for at least a couple years.
