A public hearing examining a new beer tax in Pennsylvania is set for Tuesday at the Spoonwood Brewing Company in Pittsburgh. The hearing, hosted by state Rep. Natalie Mihalek, R-Upper St. Clair, will look into the state Department of Revenue’s recent tax bulletin, which requires breweries to collect the state’s 6 percent sales tax on every portion of beer sold. The tax is set to go into effect on July 1.
