What Louis Ditzler does

Louis Ditzler AG is a Swiss family-owned manufacturer of frozen vegetables, fruits, mushrooms, and chestnut specialties, headquartered in Möhlin, Switzerland, and founded in 1925. The company processes vegetables within six hours of harvest using IQF (Individual Quick Freezing) technology and blast freezing at -40°C, working with approximately 300 contracted Swiss farmers and sourcing roughly 80% of vegetables domestically. It operates a Bäumlimattstrasse headquarters with approximately 20,000 pallet positions of frozen storage capacity, up to 150 tonnes per day of spinach processing during a 15-week season, and became the first Swiss company to introduce Optisort optical sorting for spinach in 2019. Production also extends to Bonatura AG in Kerzers (fresh convenience fruit products and one of Switzerland's most modern freezing centers, acquired 2000) and wholly-owned Chilean subsidiaries (Ditzler Chile Ltda. for sauces, fruit preparations, and co-packing since 1994; Agricola Chile Ltda. for cherry production on 100 hectares since 1991).

The business is exclusively B2B, selling through a Swiss foodservice distribution network anchored by Transgourmet/Prodega, Aligro, Pistor, and Saviva plus over 40 regional partners, with direct refrigerated-truck delivery to professional kitchens. Customer segments include professional kitchens and restaurants (primary), catering companies, mensas/staff canteens, food processing industry (private label), and the dairy industry (fruit bases for yogurt). Pricing is quote-based with a 400 kg minimum order quantity, ordering by 10:00 AM the prior day, and 30-day net payment terms. The company is led by third-generation CEO Oliver Ditzler (since 2008) and holds an extensive certification stack — Bio Suisse, Suisse Garantie, Hochstamm Suisse, IFS Food, ISO 9001/14001/45001, and EnAW — most valid through 2026. Louis Ditzler AG is privately held with no disclosed external investors, funding rounds, or parent company; revenue is not publicly disclosed.

Core offering

Louis Ditzler AG produces and supplies IQF (Individually Quick Frozen) vegetables, fruits, mushrooms, and chestnut specialties primarily for B2B customers including professional kitchens, catering companies, restaurants, and the food processing industry. The company also develops private label products and food components for industrial customers, with approximately 80% of raw materials sourced from Swiss farmers and processed within six hours of harvest.

Product overview

Louis Ditzler AG operates as a single-product frozen food portfolio rather than a unified platform. The core offering consists of six main product categories: frozen vegetables (processed within six hours of harvest using IQF technology), frozen fruits, mushrooms, Marroni chestnut specialties, spreadable products, and a Limit line of limited-availability vegetables. These are complemented by sales promotion and kitchen aid accessories. The products are primarily distributed through B2B channels to professional kitchens, catering services, and restaurants, with key differentiators being Swiss origin sourcing, IQF processing, and third-party certifications including Bio Suisse, Suisse Garantie, and IFS Food.
