"There's an extra 2 percent we're going to have to pay on every drop of beer that we pour," said Tom Baker, owner of Bar Hygge in Philadelphia's Fairmount section.
It's technically a 1.5% percent tax on the brewer and in Philadelphia, it's 2%.
Right now, Bar Hygge and Brewery Technee in Fairmount does not intend to pour that added cost onto its customers.
"What this tax has done is - more sooner than later we'll think we should raise our prices to cover this tax," said Baker.
At Love City Brewery in Spring Garden, the price of a pint of Love City Lager is going up.
"We've had to pass a different tax onto the consumer, which does increase our prices slightly," said co-founder of Love City Brewing, Melissa Walter.
"It's not a huge difference or something we wanted to do, but unfortunately the customer is paying a little more now," she says.
