EASTON, Pa. — A provision in a recently created Pennsylvania law will allow breweries to sell individual bottles of beer, something one local brewery says will allow customers to be more experimental.

A section of state law mandating sales of specific quantities of beer has been around for decades. It included descriptions of what quantities breweries could sell.

“Act 113 eliminates the requirement that sales be in quantities of at least 64 ounces,” said Pennsylvania Liquor Control Board spokeswoman Stacy Kriedeman. The changed law, which specifically affects breweries, says a licensed brewery can sell any quantity of its beer in any package or any volume for off-premises consumption.

For microbreweries selling products buyers may be unfamiliar with, the change could mean the difference between a customer trying a new, experimental flavor of beer or not.

The change is huge for small breweries, said Bill Bragg, a spokesman for Weyerbacher Brewing Co. in Easton.

“As opposed to being restricted by a relatively antiquated state rule, we’re able to let people have a chance to try samples on their own ground,” Bragg said. “They can just have a beer or two in their home instead of committing to a whole case.”

Whether it is a financial issue or just that a customer doesn’t want a case of beer they’ve never tried before, Bragg said, the changed law could mean more interest in small-batch beers.

The law only affects breweries like Weyerbacher, which does not have a sit-down restaurant on its property.

Fegley’s Brew Works in Bethlehem and Allentown have restaurants, which already required them to get a particular liquor license to sell single bottles, according to marketing manager Mike Fegley.

Fegley said he’s “happy for everybody else.”

“It’s a good decision and another small step in updating antiquated laws in Pennsylvania,” Fegley said.

About 250 new microbreweries opened in the United States in 2011, according to the Brewers Association, a national advocate for craft brewers. That number is up from 2010, when 152 opened.
