Stoneware bottle made by R. White, London (regd). It would have been stoppered with a cork.
Robert & Mary White started selling ginger beer in 1845 from their home in Camberwell. By 1869, they had five factories. The company was taken over by Whitbread in the 1960s, and by Britvic in 1986. The bottles could be returned: “R White’s ginger beer goes off pop, a penny on the bottle when you take it to the shop“. Stealing the bottles and making drinks to sell in another manufacturer’s name was a common offence – hence the ‘regd’ mark.
