2017 was historically bad for U.S. brewers, who shipped 3.8 million fewer barrels of beer than the previous year, according to the Alcohol and Tobacco Tax and Trade Bureau’s (TTB) unofficial estimate of domestic tax paid shipments. According to industry trade association the Beer Institute (BI) — which represents the interests of all brewers and importers and publishes the TTB’s monthly estimates — U.S. beer companies shipped about 170 million barrels of beer in 2017, compared to nearly 174 million barrels in 2016.
