A team of English tea-tasters employed by the tea company Lyons sample different blends for the PG Tips brand in the City of London, England UK. With variously-sourced teas from tea estate plantations, they smell, touch, sip, slurp then spit the hot drink out into a spittoon rather than swallow it many times repeatedly. Britons drink 35 million cups of PG Tips a day and world tea production is approximately 3.2 million tonnes a year. Kenya is the largest producer with Sri Lanka a close second. PG Tips is imported as single estate teas from around the world and blended in precise proportions set by the tea tasters to make blend 777, which can contain between 12 and 35 single estate teas at any one time depending on season.
