Derek Testerman

Head Brewer

Derek’s tenure with Iron Hill has taken him through our breweries in Lancaster, Chestnut Hill, Voorhees and Media. Derek began as a server at Lancaster before moving into assistant brewing.

A stint in Southern California took Derek to Gunwhale Ales, a microbrewery focused on farmhouse ales, and Riip Beer Company, known for their small batch IPAs. While out west, Derek continued to improve his brewing techniques and worked on beers that went on to win awards, including an IPA, an oyster stout and a Saison. He returned to Pennsylvania in May to work with us once again, bringing home some new West Coast tips and tricks.

A Lancaster native, Derek graduated from the American Brewers Guild in 2013. His favorite beer styles include mixed culture beers, IPAs and German lagers. Derek loves being outdoors. He enjoys traveling to national parks… and visiting new breweries along the way.
