The state in the Midwest of the USA with the capital Indianapolis was settled in 1733 by whites. It borders Lake Michigan to the north, exerting a mitigating effect on the otherwise extreme climate. The Swiss winemaker Jean Jacques Dufour (1763-1827) laid out in 1802 on the Ohio River in what is now called Switzerland County near Vevay a vineyard, which he called "New Switzerland". There he produced his first wine of high quality in 1806 or 1807, of which some barrels in the White House to the third US President Thomas Jefferson (1743-1826) were delivered. His sons continued to operate the winery until 1850. For the first time in 1968 and for some time every year in August, the "Swiss Wine Festival" is being held in Vevay, Switzerland, in honor of the Swiss immigrants here in Vevay.
