The policy is intended to increase aluminum production in the US. However, a February 1 letter from the American Beverage Association, Heineken, Pepsico, Coca-Cola, the Can Manufacturers Institute, Molson Coors, and many others cautioned about the unintended consequences of these tariffs.
"A tariff or quota will immediately disadvantage these domestic businesses," the letter read, "since foreign competitors would have the advantage of not paying an artificially inflated raw cost. We estimate a tariff of 10% on this aluminum would cost beer and beverage producers $256.3 million."
Brewers could begin to bottle beers that had previously been canned. Mark Stutrud, Founder and President of Summit Brewing, told Thrillist, "We’re fortunate, too, to operate both a canning line and a bottling line — we can keep delivering great beer to people in either package." But not every brewery is in a position with the ability to bottle or can product. For many craft breweries, transitioning would mean incurring new costs and potentially increasing the cost of beer anyhow.
