Inspired by a recent tweet, we want to explore some Guinness World Record related to tea. One world record that all tea drinkers can relate to is largest cup of tea. The record stands at 4000 liters or 16,907 cups. The cup was produced in Colombo, Sri Lanka by GlaxoSmithKline Beecham, the well-known pharmaceutical company. The record was held on October 9, 2010.
