Leiber

What Leiber does

Leiber GmbH is a German privately held manufacturer founded in 1954 and headquartered in Bramsche, Lower Saxony, with a second modern production campus opened in Engter at the end of 2023. The company specializes in brewer's yeast (Bierhefe) upcycling — its "Give Yeast a Second Life" operating principle — converting a brewing byproduct into functional ingredients for human and animal applications. With approximately 200 employees, Leiber operates eight Business Units spanning Biotechnology, Food, Nutraceuticals, Livestock, Pet & Horse, Spent Grains Trading, Contract Production, and Brewery Partnerships, serving B2B customers across roughly 35 countries through both direct field sales and a 25+ partner distribution network.

The product portfolio is organized into three core franchises built on proprietary extraction and purification technology. (1) Food ingredients: a family of yeast extracts — Leiber Aromor (neutral), Arosta (roasted/BBQ), Asada (mild roasted meaty), Bouillon (brothy), Savoury (Marmite-type), Seasonings, and Viande (meaty) — plus targeted booster products (Cheese Booster Plus, Cheese Booster Vegan, Seafood Booster, Spices Booster) and the Veaty® meat-alternative application system. (2) Nutraceuticals: Yestimun® Beta-Glucan for immune modulation, YeaProt® Sanus (EAA 45%, BCAA 21%) for sports and senior nutrition, and Interyeast® Vital for B-vitamin and protein fortification. (3) Animal nutrition: brewer's yeast-based feed supplements for ruminants, pigs, poultry, aquaculture, pets, and horses, plus spent grains (Leiber® Biertreber) trading. Supporting offerings include contract drying (Lohnproduktion) and brewery-partnership programs for sustainability/upcycling storytelling.

Leiber generates revenue as a B2B ingredients supplier with quote-based, volume- and specification-dependent pricing — specific rates are not publicly disclosed. Go-to-market combines dedicated regional field sales and key account managers (e.g., DACH/UK/Ireland, Italy, APAC, EMEA, Poland) with an extensive distribution partner network (Additive Solutions, Algol Chemicals, Will Ingredients, REDA Chemicals, SCETI, foodguys, BCI, ITS Nutriscience, Timmers Food Creations, Barentz, and others). Marketing is executed through major international trade shows (Vitafoods Europe, Interzoo, Food Ingredient Asia, J-AGRI Kumamoto, DIL Technology Day) plus LinkedIn and YouTube channels. In September 2025, Leiber implemented a new management structure to support closer international cooperation and the development of new markets.

Its portfolio includes yeast extracts for savory flavor, salt reduction, and meat alternatives (Aromor, Arosta, Asada, Bouillon, Savoury, Seasonings, Viande plus Cheese/Seafood/Spices Boosters and the Veaty system), nutraceutical ingredients (Yestimun Beta-Glucan, Interyeast Vital, YeaProt Sanus), and animal nutrition products (livestock feed additives, pet/horse nutrition, and Leiber Biertreber spent grains), plus contract drying services for food and feed ingredients.

Product overview

Leiber operates as a beer yeast upcycling company since 1954, refining brewer's yeast (Bierhefe) into innovative products across three core areas: food ingredients, nutraceuticals, and animal nutrition. The food ingredients portfolio centers on yeast extract product families including Aromor (neutral taste), Arosta (roasted/BBQ), Asada (beef substitute), Bouillon (brothy), Savoury (Marmite-type), Seasonings, and Viande (meaty), complemented by specialized boosters for cheese, seafood, and spices enhancement, and the Veaty® meat alternative system. The nutraceutical line features Yestimun® Beta-Glucan for immune modulation, YeaProt® Sanus for protein enrichment targeting sports nutrition and senior nutrition, and Interyeast® Vital for general vitality support. Animal nutrition products include spent grains (Biertreber) as feed supplements and brewer's yeast products for livestock, pets, and horses. All products derive from beer yeast upcycling, enabling the company to offer both B2B ingredients and consumer-facing health applications.
