Nearly three weeks in, the butting of heads in Washington has nullified a number of federal operations. National parks have fallen into disarray; Transportation Security Administration (TSA) employees are calling in sick rather than show up to airports to work without pay. Now the government shutdown has claimed yet another casualty: craft beer.

According to Business Insider, the federal approval process for new beers has been halted as a result of the impasse over the contested funding for border security. Labels and recipes for new beers, wines, and other alcoholic beverages are reviewed by the Alcohol and Tobacco Tax and Trade Bureau, which has closed during the shutdown. Without the bureau's stamp of approval, new and seasonal varieties of craft beers cannot be distributed or sold across state lines.

While this is not an issue for larger, mass-market offerings like Budweiser, smaller breweries that rely on an assortment of new flavors are feeling the impact. Interboro Spirits and Ales of Brooklyn releases new beers weekly; If the shutdown continues, their February sales will suffer, eating into their revenues.

But even an immediate resolution to the situation is no guarantee breweries will rebound. Because the bureau is still accepting applications for labels and even new brewery locations requiring certification, breweries will have to wait for the backlog to be cleared before being given approval to resume normal operations. Come summer, that could mean fewer craft beer options and reduced profits for small businesses that depend on a rotating selection of beverages to drive interest and fuel gatherings.

Until the shutdown is resolved, it appears a lot of craft beer will be sitting in inventory, with brewers hoping the political head-butting won’t break any records. The longest government freeze in history came in 1995, when Republicans advanced a budget met with resistance by President Bill Clinton. That lasted 21 days. Clinton later had a craft beer named in his honor, Exile Chill Clinton, which was distributed in Des Moines, Iowa. The brew was infused with 750 hemp seeds.
