Sources Rosport

What Sources Rosport does

Sources Rosport SARL is a privately held, 100% Reiffers family-owned natural mineral water producer headquartered in Contern, Luxembourg, with production based in Rosport along the Sûre river. Founded in 1955 after geologist Dr Michel Lucius identified a naturally carbonated spring — the only one in the Grand Duchy — the company began bottling operations in 1959 and operates exclusively within Luxembourg, with no export of products. The core portfolio comprises three natural mineral water brands drawn from two underground springs: Rosport Classic (strongly sparkling, 7.5 g/l CO2), Rosport Blue (lightly sparkling, 4.5 g/l CO2), and Rosport Viva (still, from a separate spring at 47m depth). The company has expanded into flavored and functional sub-brands including Rosport Pom's (apple spritzer, launched 2012), Rosport Mat (zero-calorie flavored sparkling), Rosport Sunny (still water with fruit juice), Rosport Wave (low-calorie sparkling fruit drink), and Hy/dration on Ice (electrolyte popsicles). Annual National Day limited-edition collaborations with Luxembourg artists run from 2022 through 2026.

The company's underlying technology centers on natural mineral water extraction at 5,000 liters per hour from 67m depth at a constant 12°C, with natural CO2 from volcanic/magmatic activity separated via degassing, liquefied at -30°C, and re-injected in hermetically sealed circuits at precise levels (4.5 g/l Blue, 7.5 g/l Classic). Since June 2024, Sources Rosport blow-molds its PET bottles on-site from 100% recycled plastic with attached caps per EU Directive 2019/904. Glass bottles are refillable up to 50 times through a deposit-return system. The company holds ISO 9001, ISO 14001, ISO 45001, Made in Luxembourg, ESR, SuperDrecksKëscht, Responsibility Europe, and AAA certifications, and has been Official Supplier to the Grand Ducal Court since 1967.

The business model is single-channel by design: all products are sold domestically through retail (supermarkets, convenience stores, petrol stations), HORECA (managed by two dedicated ambassadors, Eric Kallen and Marcel Monheim), beverage wholesalers and depositaries, and Letzshop e-commerce for select SKUs. Revenue streams are one-time retail and HORECA sales with quote-based pricing for business partners; no subscription, licensing, or recurring revenue model exists. The company has approximately 15 disclosed employees plus a named management roster covering production, quality, accounting/HR, communication/events, and HORECA — functioning as a tightly run family-owned SME where founder/owner Max Weber serves as Director.
