[2] Henry's son Abraham Overholt encouraged the production of rye whiskey in 1810 to be sold commercially.
Henry agreed and the Overholts' became the first to produce rye whiskey in Pennsylvania for commercial consumption instead of strictly for medicinal purposes.
It operated nearby at Broad Ford and produced the brands known as “Old Overholt” or “Monongahela Rye".
Together Abraham and Christian built up and enlarged the distillery which now had the production capacity of almost 200 gallons of rye whiskey per day.
[2] The Overholt distillery was purchased by Henry's granddaughter Helen Clay Frick and refurbished into a museum.
