Weyermann® began the production of high-quality malts and malt derived products in Bamberg over Founded 140 years ago, Weyermann® Specialty Malts has ascended to become the global leader in the production of caramel and roasting malts. With an extensive range of over 90 unique products, the influence of Weyermann® malts extends to the color and flavor profiles of more than 60,000 beers across 135 countries on every continent. The company’s red and yellow logo has evolved into a symbol of superior German malt, revered by both brewers and beer aficionados worldwide.
Although the Weyermann® Specialty Malts facility is a designated historical landmark with its red-brick facade dating back to the turn of the 20th century, it houses a state-of-the-art malt production operation. Under the stewardship of Sabine Weyermann, a fourth-generation descendant of the founding family, and her spouse, Thomas Kraus-Weyermann, the enterprise thrives on a blend of rich heritage and contemporary malting techniques. This synthesis of tradition and modernity serves as a cornerstone for the company’s continued success in the specialty malt industry.
The earliest records show that the name “Weyermann” appeared in the city’s “Immunitätenbuch,” or citizen registry, in 1510. For generations, the family was engaged in fishing and shipping on the Regnitz and Main rivers. The Weyermanns ventured into the grain business in 1871.
Michael Weyermann, the family patriarch, was born in 1817 in the charming Little-Venice quarter of Bamberg. Following in his father’s footsteps, he became a skipper and later expanded into the grain trade. His son, Johann Baptist Weyermann, was born in 1853 and later took over the grain store. In 1879, Johann Baptist founded Mich. Weyermann’s Malzkaffee Fabrik, a malt coffee factory. The initial setup was modest, consisting of a small roasting drum under a tarpaulin. Due to business growth, Johann Baptist opened a new factory for specialty malts at its current location in 1888.
The company’s products soon gained recognition for their quality, exemplified by a host of awards and the 1896 registration of their first trademark, “Gambrinus.” In 1902, Johann Baptist developed a unique roast malt beer named “SINAMAR” and secured a patent for its production process. Initially produced in Bamberg, SINAMAR production was later moved to Potsdam in 1907 due to tax considerations. The brand CARAPILS® was nationally registered in 1908, marking another milestone in the company’s trajectory.
After Johann Baptist’s passing in 1919, his widow Sabine and their sons Rudolf and Carl continued to run the business. The year 1924 saw the registration of a range of new malt products, including CARAMÜNCH®, CARAWIEN®, CARAHELL®, CARADUNKEL®, and CARAFA®. In 1929, the company celebrated its 50th anniversary with grand festivities in a newly constructed ballroom. At this time, Weyermann® products were exported to more than 30 countries.
During World War II, the Potsdam factory was destroyed, leading to the loss of the family’s East German operations. After the war, Rudolf and Carl Weyermann were temporarily removed from the company as part of the de-Nazification process. The production of SINAMAR resumed in Bamberg in 1948 under the brand “Roastmaltbeer Brewery Heinz Weyermann,” using equipment salvaged from the Potsdam facility. By 1954, the business was being managed by the next generation—cousins Rolf and Heinz Weyermann.
In 1979, Sabine Weyermann joined the management team, refocusing the company on specialty malts. Her husband Thomas Kraus-Weyermann joined her in 1991. In 1992, they built a new malthouse, signaling a bold vision for the future. Four years later, the company made its debut at the craft brewers conference, marking its role as an influencer in the malting industry. They also invested in new technology like automatic bagging systems and advanced brewing equipment.
By 2001, Weyermann acquired a production facility for base malts in Haßfurt, positioned near the Rhine-Main-Danube Canal for easy transport. In 2005, they bought a grain elevator in Leesau, later expanding its storage capacity in 2011 to 45,000 tons. In response to rising demand for roasted malts in 2008, the company increased its roasting capacity and installed an additional 42 storage silos.
In 2010, Sabine Weyermann celebrated 25 years as managing director. Three years later, the company made unique strides in beer expertise by training management and staff as beer sommeliers. They also entered the spirits market with their first whiskey. That year also saw significant growth in logistics, with 1.6 million bags shipped annually and the introduction of QR code scanning for product information.
In 2014, Weyermann responded to demand by investing in a high-performance bagging plant and expanding storage at a new site. The same year marked their 135th anniversary, celebrating a production volume of 90,000 tons of malt in 85 varieties. By 2015, the company consolidated its various departments in a newly acquired and renovated site, which also featured a new fan shop and distillery.
In 2015, Weyermann® Malts relocated its marketing, accounting, controlling, and IT departments to a renovated site in Bamberg, also introducing a Fan Shop and visitors’ center. The following year, the company overcame extensive storm damage by renewing five of its eight 700-ton silos and modernizing its logistics and barley reception areas.
In 2017, Weyermann® acquired Thüringen Malz to meet growing demand for specialty malts. The next year was marked by a severe kiln fire causing 1.5 million Euros in damages but was swiftly controlled, averting any injuries. The company also expanded its logistics and introduced its first whisky line.
The Covid-19 pandemic in 2020 led Weyermann® to produce ethanol for sanitizers, supplied to local pharmacies at cost. The same year saw extensive modernizations at the Clingen malthouse, now powered entirely by green energy.
In 2021, Weyermann® upgraded its Bamberg facility and significantly expanded the capacity of the Heinz Weyermann® Roasted Malt Brewery with new, environmentally friendly equipment.
By 2022, further technical advancements in the brewery allowed for customized malt extracts, accommodating even small batches of specialty malts.
