Gregg Bonstein

Co-Owner / Head Brewer

Gregg Bonstein, Owner and Head Brewer, formerly a Quality Manager and Chemical Engineer left his day job back in Feb 2017 to pursue his dream of starting a craft brewery. He has since worked as a brewer at Triumph Brewing in New Hope and Blueprint Brewing in Harleysville. Taking classes at the Siebel Institute and getting certifications as a BJCP judge and Cicerone only cemented the fact that this was his passion.


Living in Newtown with his wife Sara of 11 years and their two boys 8 and 9, it was their dream to bring the first brewery to this historic and affluent town. 


Besides brewing, Gregg enjoys running, watching cheesy 80s movies, and telling people he's related to the Incredible Hulk.

Sara Bonstein

Co-Owner / Chief Financial Officer

Sara Bonstein, Owner and Head Business Lady, handles all of our financial, business, HR, and administrative duties. She comes with the chops to back it up too, as a seasoned strategic and financial executive with 15+ years of experience in the public biotechnology and pharmaceutical industry, where she has raised ~$300 million in the capital marketplace and licensing deals. Currently, she serves as the Chief Financial Officer for a publicly-traded global biopharmaceutical company focusing on transforming the lives of patients with serious and rare diseases.


Partnered along with her husband Gregg, the Head Brewer, they make a great team and can't wait to bring a new fresh local business to Newtown that will be family owned and run.


Besides kicking butt in the business world, Sara enjoys taking classes at the NAC, chai lattes, and playing card games / board games with her two boys - anything to get them off the electronics!
