Wellpark Brewery was originally known as the Drygate Brewery. It was founded as H&R Tennent in 1740 at Drygate Bridge, near Glasgow Cathedral, by Hugh and Robert Tennent, although brewing had been taking place at the same site on the banks of the Molendinar Burn since 1556, making it the oldest continuous commercial concern in Glasgow.

Hugh Tennent's sons, John and Robert, continued the family business, trading as J&R Tennent from 1769. The business expanded in the 1790s when the Tennent family purchased the neighbouring brewery of William McLehose, and renamed the 5-acre (20,000 m2) site Wellpark Brewery.

The firm originally brewed stout and strong export ales. By the mid-19th century J&R Tennent was the world's largest bottled beer exporter. Robert Tennent died in 1826 and John Tennent in 1827. Hugh Tennent (the eldest son of Robert) then assumed control of the business. Hugh Tennent retired in 1855 with his fifth son, Charles Tennent, taking over, but he died in 1864, some months before his father. The brewery was subsequently operated by trustees on behalf of Charles Tennent’s sons, Archibald and Hugh.

In 1884 Hugh Tennent took control of the company and first brewed Tennent's lager in 1885. He later built a new lager brewery on the Wellpark site, which was begun in 1889 and completed in 1891. J&R Tennent produced the first draught lager in 1924, the first canned lager in 1935 and the first keg lager in 1963.

J&R Tennent was acquired by Charrington United Breweries in 1963, and in 1966 formally merged with United Caledonian Breweries, Charrington's other Scottish subsidiary, to form Tennent Caledonian Breweries.
