Brewing

Philosophy

Multiple breweries have occupied this city—many right in this neighborhood, block and even this building. Mainstay Independent recognizes the legacy we are celebrating, the opportunities we are embracing and we pledge to brew the finest beer available anywhere.

We serve honest beer brewed traditionally with experience and a balance of art and science…Mainstay Independent’s objective is to explore the full breadth of the craft in an environment that supports makers.

Meet The

Brewmaster

One of Philadelphia’s best known beer makers, Brian O’Reilly spent the last chunk of his career turning a suburban brewpub into a regional powerhouse, with respected recipes and a broad portfolio.

Awarded dozens of brewing awards including 10 Great American Beer Festival medals, O’Reilly has brewed and formulated hundreds of beer recipes over the years and now, he is excited to expand that portfolio at Mainstay.

As a second act, Mainstay Independent is a creative dream for brewmaster Brian O’Reilly whose passion for creating authentic beer and original drinking experiences runs deep.
