William Penn's Brew House at Pennsbury, c 1682
Excerpt from Brewed In America by Stanley Baron, 1962
Penn himself was enough of a beer-drinker to have a brewhouse constructed at the estate he built in Pennsbury, Bucks County, twenty miles upriver from Philadelphia. At a cost of about £7000 and over a period of many years, the manor-house was erected under Penn's supervision, although he was most of that time back in England. He made a start on the project soon after his arrival in 1682, but he had to return to England in 1684. He commissioned his trusted friend James Harrison as "Steward of the Household at Pennsbury," and from that date until his return, he wrote frequent letters, filled with details about the house's specifications, the gardens, the servants, slaves, etc. "I would have a Kitchen," he wrote from London after he returned there in 1684, "two larders, a wash house & room to iron in, a brew house & in it an oven for bakeing."
