Wild Yeast Bakehouse opens Wayne sourdough bakery after home start

Wild Yeast Bakehouse opened its first Wayne storefront on July 18, turning a Rosemont home-baking operation into a brick-and-mortar stop built around sourdough, subscriptions and steady weekly demand. The bakery’s own motto says the pitch in plain language: “Bread as it was meant to be: Wholesome, Uncomplicated, Shared.”

That philosophy is the main reason sourdough regulars may want to stop in. Wild Yeast Bakehouse has positioned Bread Share as a subscription model for weekly bread delivery, closer to a CSA than a standard bakery case stacked with pastries and coffee-shop add-ons. For home bakers, that model is the most revealing part of the business: it shows how a single starter-led operation can become predictable enough to support recurring pickups and weekly production, not just occasional special orders.

John Goncher’s path explains why the bakery feels more like a long-fermented project than a quick retail launch. The bakery’s story page says he changed careers in 2019 after nearly 30 years in finance. By March 3, 2025, a YouTube interview showed him turning his former living room into a micro-bakery and experimenting with sourdough bread. The progression was already visible by then: in April 2021, he was baking the first loaves at a kitchen table and delivering them to a small handful of customers.

A Philadelphia Inquirer clipping hosted by the bakery puts hard numbers on how far that home setup went. Goncher was baking about 350 loaves each week at his home in Rosemont, and about a third of them went to the Media farmers market every Sunday. The rest went to wholesale clients and Bread Share subscribers. The clipping also described Wild Yeast Bakehouse as a one-man sourdough bakery and said it regularly sold out at the market, a useful clue for anyone judging whether a similar home operation has real neighborhood pull.

The Wayne opening, which Patch identified as the bakery’s first storefront on the Main Line, gives that model a more permanent address. Main Line Media News later said the shop cut the ribbon on July 19, 2026, one day after the doors opened. For sourdough bakers watching the jump from microbakery to retail, the takeaway is straightforward: recurring subscribers, a clear bread philosophy and enough weekly volume to sell out at market were the proof before the lease ever was.
