How It’s Made
72 Hours of Patience
Most commercial bread is made start-to-finish in under an hour. Ours takes three full days — and every hour matters.
The Starter
A live culture of wild yeast and beneficial bacteria — fed daily, alive, and active. This is the engine of flavor. Nothing manufactured. Nothing instant.
The Mix
Flour, water, salt, and starter — that’s it. No dough conditioners. No preservatives. No emulsifiers. Just the four ingredients bread has always needed.
The Ferment
We cold-ferment each loaf for over 72 hours. The slow rise develops deep flavor, natural tang, and a open, chewy crumb structure you simply cannot rush into existence.
The Bake
High heat. Cast iron. Steam in the first minutes to set a crackling, deeply caramelized crust. Baked fresh every morning before the diner opens.
Watch the Craft
See It Come to Life
The process is hard to describe in words alone. Watch what 72 hours of slow fermentation looks and sounds like when it hits the oven.
Why It Matters
This Isn’t a Trend.
It’s How Bread Used to Be.
Sourdough is one of humanity’s oldest foods — dating back to ancient Egypt. For most of history, all bread was fermented bread. The industrial revolution changed that, trading flavor and digestibility for speed and shelf life. We chose to go back.
Easier to Digest
Long fermentation breaks down gluten proteins and phytic acid, making nutrients more available and the bread gentler on the gut.
Lower Glycemic Response
The acetic acid produced during fermentation slows starch digestion, resulting in a more gradual blood sugar curve compared to commercial bread.
Naturally Preserved
The organic acids created by fermentation inhibit mold growth — no additives needed. A well-made sourdough keeps for days at room temperature.
Complex, Real Flavor
No yeast packet can replicate what 72 hours of wild fermentation builds — that layered tang, the depth, the crust that shatters when you break it.
