In 1814, a flour miller from Norfolk made a decision that would transform a small village watermill into one of Britain's most recognisable food brands. Jeremiah Colman's purchase of Edward Ames' mustard business at Stoke Holy Cross, four miles south of Norwich, marked the beginning of an industrial legacy that would employ thousands, shape social welfare policy, and put Norwich on the global culinary map.
From Flour to Mustard
Jeremiah Colman was born in 1777, the son of Robert and Mary Colman. By 1803, he had already established himself as a miller, purchasing the Pockthorpe mill in Norwich. A decade of milling experience provided the foundation for his 1814 expansion into mustard production. The Stoke Holy Cross watermill, situated on the River Tas, became the site where Colman began blending brown mustard (Brassica juncea) with white mustard (Sinapis alba) to create a distinctive tangy flavour that would define the brand for centuries.
The business grew steadily. In 1823, Colman took his adopted nephew James into partnership, renaming the firm J. & J. Colman. A London branch followed in 1836, signalling ambitions that extended far beyond Norfolk.
The Move to Carrow
The most significant expansion came in the 1850s. In 1850, Colman purchased land at Carrow from the Norfolk Railway Company. Between 1854 and 1856, the firm erected a mustard mill on the site. The move from Stoke Holy Cross began immediately, with production fully transferred to the new Carrow Works by 1865.
The timing proved crucial. Jeremiah Colman died in 1851, aged 74, leaving the business to his great-nephew Jeremiah James Colman. The younger Colman, then just 21, inherited a firm employing 200 workers. Under his leadership, the Carrow site would eventually sprawl across 40 acres and become one of Norwich's largest employers.
The Yellow Packaging Revolution
In 1855, the company introduced the distinctive yellow packaging and bull's-head logo that remain instantly recognisable today. This visual branding coincided with a remarkable ascent in social standing. In 1866, Queen Victoria granted J. & J. Colman a Royal Warrant as manufacturers of mustard. The firm's reputation extended to continental royalty; Napoleon III of France, the Prince of Wales, and Victor Emmanuel II of Italy all counted among its customers.
Industrial Paternalism and Social Innovation
Jeremiah James Colman distinguished himself not merely as a businessman but as a pioneer of industrial welfare. In 1856, he became a founding member and first treasurer of the Norwich YMCA, serving as its president from 1860 to 1898. The following year, he opened a school for employees' children at Carrow. By 1864, a new school building on Carrow Hill was completed, alongside the Carrow Works Dispensary.
That same year, Colman appointed the first industrial nurse in Britain to help sick staff. Philippa Flowerday, who took up the post in 1878, became a national pioneer in occupational health. The firm established a kitchen in 1868 to provide hot meals at affordable prices, and in 1899 introduced the Carrow Works Pension Fund as a memorial to J.J. Colman.
These innovations were decades ahead of legislative requirements. By 1874, Colman was master of 1,500 workers; by 1893, employment exceeded 2,000. The company owned hundreds of properties around Norwich, providing housing at Carrow Close and Nightingale Cottages.
A Political Dynasty
Colman's influence extended into public life. Jeremiah Colman served as Sheriff of Norwich in 1845 and Mayor in 1846. His great-nephew matched and exceeded this record: Norwich councillor from 1859 to 1871, Sheriff in 1862, Mayor in 1867, and Member of Parliament for Norwich from 1871 to 1895. In 1893, he became an Honorary Freeman of Norwich.
His wife Caroline, whom he married in 1856, played an equally significant role. After their son's recovery at the Jenny Lind Hospital in 1863, she became closely associated with the institution. Following her death in 1895, J.J. Colman donated a new site for the hospital in her memory.
The Family Legacy
The Colman family left an indelible mark on Norwich's built environment. In 1878, the firm purchased Carrow Abbey, a Grade I listed former Benedictine priory founded in 1146. The family hosted the Prince of Wales, later Edward VII, there in July 1900. Sir Jeremiah Colman, 1st Baronet (1859–1942), son of James Colman, served as chairman from 1896 and was created a baronet in 1907.
Ethel Colman, daughter of J.J. Colman, became the first woman Lord Mayor of Norwich. The family name persists in Colman Road, Colman First and Middle Schools, and Colman House at the University of East Anglia.
Expansion and Acquisition
The twentieth century brought further growth. In 1903, the firm acquired rival Keen Robinson & Company, founded in 1742, along with Robinsons barley water and baby food business. By 1909, Colman's employed 2,300 people in a city of fewer than 120,000 residents.
In 1926, Colman partnered with Reckitt to acquire French's, the American mustard manufacturer, for £750,000. The 1938 merger with Reckitt & Sons created Reckitt & Colman. Unilever acquired the brand in 1995.
The End of an Era
The announcement in January 2018 that Colman's would leave Norwich after more than 160 years marked the end of an industrial epoch. The final jar rolled off the production line on 24 July 2019, bearing a special label reading "Norwich's Last. By Its Finest. July 24th 2019." The Carrow Works site closed on 22 May 2020.
Britvic had already departed in December 2017, taking 249 jobs. Of the 113 remaining Colman's employees, 43 transferred to Burton-upon-Trent and 20 to a new Norwich facility. A new mustard milling and mint processing plant opened at Honingham, near Norwich, in 2019, expected to employ 25 people.
What Remains
Despite production moving to Burton and Germany, the "Colman's of Norwich" branding persists on packaging. The city council purchased Carrow House in 2021 for over £2 million, with plans for refurbishment. Redevelopment proposals for the wider Carrow Works site, including 1,859 homes at a projected cost of £460 million, were scrapped in March 2024.
The Mustard Shop, which traded from Bridewell Alley from 1973 before relocating to the Royal Arcade in 1999, closed its doors in April 2017. Yet the bull's-head logo and yellow tins remain fixtures in British kitchens, a lasting testament to the Norfolk miller who turned a kitchen experiment into a global brand.
