Tea grows best in tropical and sub-tropical climates. One-half of the world's tea is grown in China and India. Rounding out the list of the top tea-producing countries in the world are (in order of % of production) Kenya, Sri Lanka, Turkey, Indonesia, Vietnam, Japan, Argentina, Bangladesh, Iran, Malawi, and Uganda.
You may therefore find it interesting that tea is also grown in Jolly Old England - at Tregothnan in Cornwall.
Home to the Boscawen family since 1335, Tregothnan is internationally known for its fine 'English Estate' products grown and produced there such as honey, Kea Plum jam, flowers, wood - and now, tea.
Two hundred years ago, Tregothnan was the first to grow the Camellia ornamentally outdoors. More recently, seven years of secret trials there have culminated in true, 100% English tea being grown on English soil - the first English tea grown in England.
Tregothnan produces black and green tea blends with their tea, as well as occasionally offering a very limited edition of their 100% single estate tea.
And I find all of this simply unique.
