Otto Graf GmbH

Otto Graf GmbH was established in 1962. We spent our early years almost exclusively selling containers, barrels and tanks for winegrowers and wineries. We systematically utilised the advantage that plastic’s acid and alkali resistance offers, and also started to focus on tanks for industrial applications. Within a matter of a few years, we had achieved a leading position in this industry. We picked up on the considerable potential offered by rainwater harvesting early on. In 1974, the slogan Rainwater is free was used to market the very first rainwater barrels, which were soon followed by other innovations for rainwater harvesting. We have been consistently developing this area of our business ever since. GRAF products are sold in more than 80 countries around the world.
