Steiner mill

What Steiner mill does

Steiner Mühle AG, founded in 1995, is a Swiss food-processing company operating as a wholly-owned subsidiary of Groupe Minoteries SA (GMSA). It runs milling operations in Zollbrück, Switzerland, and is positioned as the only pure organic/biodynamic mill (Biomühle) in Switzerland, processing exclusively biodynamic and organic grain. Its parent GMSA is described as the market leader (Marktführer) in Swiss grain products and operates additional milling facilities including Moulin du Valais SA in Riddes. The group's commercial footprint covers bakeries and gastronomy (its primary segment), industrial food manufacturers, and retail/wholesale distribution, all within the domestic Swiss market.

Core activity centers on milling wheat and other grains into flour and animal feed, with 99% of grain kernels processed into usable output and the balance valorized through biogas plants. Over 80% of bread grain is sourced from Swiss farms within 100 km of the two main production sites, and approximately three-quarters of raw materials carry organic or extensive-agriculture certification. Packaging is 90% paper-based, with technology-development partnerships targeting further renewable-material substitution. Distribution is direct B2B to bakeries and industrial customers, plus retail/wholesale channels, with sales-led go-to-market and no disclosed digital or direct-to-consumer infrastructure.

Revenue is generated through one-time product sales of flour and grain products; no pricing is publicly disclosed. The group invests in sustainability — energy efficiency (via a partnership with the Swiss Energie-Agentur), CO2 reduction (documented in a published reduction roadmap), fleet renewal, employee wellbeing (zero-accident goal by 2030), and stakeholder engagement (open-door events). It maintains a corporate website, LinkedIn presence, and media communications, but operates with no app, API, or disclosed technology platform beyond conventional milling.
