Its capital is Dispur. Assamese is the predominant language of the state. Its major festivals include Rongali or Bohag Bihu, Kati Bihu, Magh or Bhogali Bihu and Durga Puja.
Assam, like Darjeeling, is a renowned tea growing region of India. Unlike the majority of premium black tea, Assam tea is grown at elevations near sea level, giving it a malty sweetness and an earthy flavor, as opposed to the more floral aroma of highland (e.g. Darjeeling) tea.
Assam also produces crude oil and natural gas. It has been producing crude oil for more than one hundred years. Most of the oilfields of Assam are located in the Upper Assam region of the Brahmaputra Valley.
