What Carl Siegert does

Carl Siegert (legal entity: Bakkerij Carl Siegert sinds 1891 b.v.) is a sixth-generation, family-owned artisan bakery headquartered in Harmelen, municipality of Woerden, Netherlands, founded in 1891 and employing approximately 35 people. The company produces a broad assortment of predominantly organic (SKAL-certified) sourdough bread and bread specialties — including brioche rolls, gourmet burger buns, large sourdough loaves, and breakable/shareable breads — for the Dutch out-of-home (horeca) hospitality market. Core technology revolves around long-fermentation desem sourdough craft, shock-freezing baked goods to -35°C for the vriesvers (pre-baked/frozen-fresh) distribution format, and a proprietary vacuum cooling (Vacuümkoelen) method introduced in 2024 that keeps thawed bread crispy without oven reheating. Circular-economy sourcing integrates brewer's spent grain (bierbostel) from Gulpener Bierbrouwerij into the Puurzaam line and potato residues from FrietHoes into the Gigabol Potato bun.

The business model is B2B wholesale only, with no direct-to-consumer retail. Distribution is executed through direct sales by a small commercial team (commercial and operational director Michel Schröder and Ruud Nederend), supported by a free-sample request workflow, brochure-based quoting, and recurring presence at five major Dutch horeca trade fairs (Horecava, BBB Maastricht, Gastvrij Rotterdam, HorecaEvenTT, Horecabeurs Goes). Pricing is not publicly disclosed and is quotation-based. Certifications include SKAL Biologisch (organic, valid through 1 January 2028) and IFS food safety; the bakery additionally holds the Predicaat Hofleverancier (Royal Supplier) warrant through 2042 and generates approximately 40% of its energy from ~1,000 solar panels installed on its production facility.

Customers are exclusively Dutch hospitality operators — restaurants, hotels, and caterers — illustrated by named users such as Podomoro (Spakenburg, NK Lekkerste Burger 2024 winner) and Kwalitaria Prinsenland (NK Lekkerste Burger 2024, 3rd place). The company has broadened its assortment through recurring product launches (Kornheimer Desembrood BIO, Brioche Vlechtbroodje, Ciabatta Desem BIO, Pan Brioche Gesneden) and licensed collaborations such as the Nijntje Broodje Wit BIO with Mercis and Centraal Museum Utrecht. No external funding rounds, parent companies, or M&A activity have been disclosed; ownership remains concentrated in the founding family with non-family professional management layered on.
