Which British lemonade brand has been sold in the UK since 1845?

The British lemonade brand sold in the UK since 1845 is R. White’s.

R. White’s began selling lemonade during the rapid expansion of Britain’s soft-drink industry. By the mid-19th century, carbonated drinks were becoming widely available at refreshment stalls, and the brand became especially prominent in London and southeast England.

The date places R. White’s among the early commercial lemonade producers of the modern soft-drink era. It followed the spread of carbonated-water technology and the growth of bottled beverages, which made lemonade easier to distribute beyond cafés, street vendors, and local refreshment stands.

A common mistake is to choose Schweppes because it is an older and internationally famous British soft-drinks company. Schweppes was associated with the Great Exhibition of 1851, but the specific “sold in the UK since 1845” clue identifies R. White’s. The brand later became famous for advertising built around its “secret lemonade drinker” campaign.
