Rio Grande do Sul (; lit. "Great Southern River") is the southernmost state in Brazil, and the state with the fourth highest Human Development Index (HDI) in the country, and the third and last in the Brazilian South Region, with by far the highest standard of living. In this state is located the southernmost city in the country, Chuí, on the border with Uruguay. In the region of Bento Gonçalves and Caxias do Sul, the largest wine producing center in Brazil, the attraction is Italian gastronomy. Besides the European influence, the gaúchos, or inhabitants of Rio Grande do Sul, strongly cultivate the traditions of the Pampas – region of the border with Uruguay and Argentina – such as drinking mate (known as chimarrão drunk in special gourd cups), eating the typical barbecue, known as churrasco, and the traditional clothes are the bombachas (baggy trousers), boots and large hats. Although the majority of the population dresses non-traditionally, there is a widespread value for tradition and culture, which renders the image of "cultural zealots" sometimes attributed to the gaúchos.
