Pickwick tea
Pickwick is a tea brand, marketed by Dutch company JDE Peet's. It is the largest tea brand in the Netherlands and the leading brand in market share of black tea there, although its share has been decreasing due to competition. As of 2014, it is also the leading tea brand in Denmark, with 27% of market share. In 1753, Egbert Douwe and his wife, Akken, opened a coffee, tea, and tobacco kiosk on Main Street in Joure, Friesland. Until 1937, all the company's teas were produced under the Douwe Egberts brand; each box had an English postage stamp as a symbol. In the 1930s, the company was headed by Johannes Hessel, whose wife loved to read Charles Dickens. Impressed by the novel about Mr. Pickwick's adventures, he suggested changing the name of the tea to "Pikvik". In any case, the legend of the brand change was translated from Dutch into "London" on the company's official website.
