Interboro Spirits and Ales happily pumps over 100 kegs of beer every week from their East Williamsburg brewery and distillery.

Every two weeks, they release a new beer to the delight of suds lovers in the city and beyond.

But the company's business is threatened by the deadlock in Washington.

"The government shutdown is a crazy thing for us," said Laura Dierks, the CEO of Interboro Spirits and Ales.

That's because the federal Alcohol and Tobacco Tax and Trade Bureau must approve most new beer recipes, and then approve the products' labels so the items can be shipped out of state. Those approvals, however, have been halted by the partial government shutdown.

Companies like Interboro whose business model depends on rolling out new brews are out of luck.

"It may not seem like it be that big of a deal," Dierks said. "OK, we do something else, but the problem is the federal government regulates interstate commerce so if we want to sell our beer or any of our products outside the state of New York, we have to have these approvals from the federal government."

About 20 percent of Interboro's growing business comes from exporting out of state, to places like New Jersey, Massachusetts and Maine.

Shipments planned in the coming weeks are in jeopardy, potentially costing Interboro tens of thousands of dollars in lost revenue.

"Beer can’t ship there, which means we can't sell it there, which means our customers in those markets can't get the beer, and we can't get the revenue in order to pay the rent to pay the employees to make the next batch of beer," Dierks said. "It's really a problem."

But the government shutdown isn't the only problem.

What happens when Interboro reopens is also a cause for concern.

"The backlog is going to be a problem," Dierks said. "I don’t know how delayed things will be, how many people have submitted, and how much is now waiting. We are submitting for our label approvals because I'm concerned that it's just queuing up and I want to be in the line."

Interboro is exploring whether some vendors will take deliveries knowing sales will require pending federal approval.

Interboro produces 100 to 150 kegs of beer a week, lots of suds that won't get sold if the government doesn't fully reopen soon.
