Mim Tea Estate is in the Darjeeling area of Northern India. It is located in Sukhiapokhri of Darjeeling district in Eastern India at an elevation from 600 to 2000 meters. The fragrance and taste is a complex bouquet that reaches right out of the cup. Some would describe the taste as nutty, but most often it is described as similar to the taste and fragrance of muscat grapes. The flavor also displays a tinge of astringent tannic characteristic and a musky spiciness often referred to by tea connoisseurs as "muscatel". The genus of the Darjeeling tea bush is the Chinese Jat, which gives it the distinctive muscatel character. Because the tea is grown at such high altitudes and in relatively cool weather the bushes do not grow quickly, and as such the production is limited (about 254,000 lbs annually). The town of Mim Tea Estate has a total population of 1,842 peoples. 

Castleton Tea Estate is near the town of Kurseong in the Darjeeling district of North-East India. Castleton is one of the top estates in Darjeeling and consistently produces top teas. It is located at an altitude ranging from 980 to 2300 meters spanning the hilly slopes of Kurseong and Pankhabari. It has a planted area of around 420 acres which produces one of the world’s best muscatels. The annual production stands around 31,000 kgs. This tea has a remarkably mellow flavor with a splendid bouquet of fruits and fresh spring blossoms - a bright tasting, full-bodied tea that is as satiating as it gets. The clean notes of citrus and sweet greens dominate the top of the palate as the brisk tea fills the sense with wonder. From citrus blossom, fresh nuts and apricot in the subtle notes to ripe stone fruits and a gentle floral undertone all merged into a consistent profile.
