September is the time where things get cooler, the leaves change color, we all want to be snuggled up in sweaters and boots… and it's time for Oktoberfest celebrations.Oktoberfest began in Bavaria when a prince married his princess and invited the citizens of Munich to attend festivities.The decision was made to celebrate the marriage every year afterward and the idea grew around the world, resulting in Oktoberfest from mid-September through the first weekend in October.We like to celebrate here in Pittsburgh, so here’s a list of Oktoberfest festivities on weekends this month.Tapping Party - Every Saturday and Sunday in Oct - The Church Brew WorksIt’s a party every weekend in Lawrenceville with traditional German music.More information: churchbrew.comPenn Brewery Oktoberfest - Sept 23-25 - Penn BreweryWhat better place to celebrate Oktoberfest than a brewery with no cover charge?
