Jacksons of Piccadilly was a London tea house, tea wholesaler and retailer, grocer, wine merchant, and deluxe department store, founded by Robert Jackson in Piccadilly in 1700.
[1] It is now a brand owned by R. Twinings and Company Limited, a former tea business rival.
An example of Jacksons' blending ability was its "The Lady Londonderry Mixture Tea".
It was a blend of teas from the foothills of Ceylon (now Sri Lanka), the hills of Darjeeling district (in West Bengal state in India), and the tea gardens of Formosa (now the island of Taiwan).
[5] The company also claims (although this is contested) to have invented the "original" recipe for Earl Grey tea, Grey having given the recipe to Robert Jackson & Co. partner, George Charlton, in 1830.
