Hart Bageri

Dough read by hand in Frederiksberg

The sourdough tells Richard Hart, co-founder and chef at Hart Bageri in Frederiksberg, Copenhagen, when to wait and when to bake. That judgment, built through repetition rather than display, is the line that runs from London kitchens with Gordon Ramsay to Ubuntu in the United States from 2007, then to Della Fattoria in Petaluma and the head baker’s bench at Tartine Bakery in San Francisco. At Hart Bageri, opened in 2018 on Gammel Kongevej, he placed that bread discipline inside a Danish bakery rather than a restaurant kitchen, with sourdough as the common thread and pastry sharing the same attention to fermentation, texture, and color.

Hart’s role here is not only authorship. He co-founded the bakery and remains in post, shaping a program that has grown beyond the Frederiksberg original into Copenhagen neighborhoods while keeping the work legible at the counter. His later founding of Green Rhino in 2025 shows the practice still moving, but Hart Bageri is the Copenhagen address where his California bread training and Danish forms meet most directly. The lineage is practical: dough handled often enough that instinct becomes a method.

Organic grain through the mill

The bakery’s craft starts before the bench, with organic grains milled on site and folded into a program built around natural leavening and slow fermentation. The house is known for traditional sourdough, but the same appetite for controlled patience sits inside the pastry case: cardamom croissant, spandauer, almond croissant, cheesecake, sausage roll. These are not separate gestures. Lamination, proofing, filling, baking and holding each ask the baker to judge a material in motion.

Hart Bageri’s signature is less a single item than a way of letting Danish shapes carry an international breadmaker’s habits. The cardamom croissant brings spice into a layered bake; the spandauer keeps the old Danish reference visible; the sourdough loaf holds the darker, chewier language of fermentation. Coffee and beer sit alongside the baking, with artisanal coffee doing most of the daily work against butter, grain and sugar. The bakery does not need a long menu to make its point. It needs the next tray to land cleanly.

The counter before the city wakes

The room is small, bright and close to the work. Fresh-baked air reaches the counter before the line has settled, and the morning crowd gives the place its rhythm: orders called, pastries lifted, loaves moving from shelf to paper, coffee passing hand to hand. Seating stays limited, with 2-3 tables inside, so the bakery behaves like both a neighborhood pause and a moving production line. The Scandinavian restraint of the room matters because it leaves the bench in charge.

Counter service suits the craft. Nothing about the exchange asks the pastry to perform beyond itself; the cardamom, butter, crumb and crust carry the conversation. At Gammel Kongevej, the original address still gives the expanding Hart Bageri map its center, a compact room where Richard Hart’s sourdough practice meets the cardamom croissant.
