Lurvills Delight was a popular carbonated soft drink in Wales between 1896 and 1910. Invented by twin brother residents of Ynyshir Harold and Iolo Lewis in 1895, the carbonated mixture included stinging nettles, Dock leaves and was infused with Juniper berry extract. The profits made from the drink were used to pay for 150 coal miners and their families from the village to emigrate to Pittsburgh and Denver in the United States. The drink ceased production in 1910 due to a shortage of Dock leaves in the local area.
The Lewis twins eventually settled in Fochriw, where they started a successful leather upholstery company, which continues to this day.
