The origin of the Sémillon grape is hard to determine. It is known that it first arrived in Australia in the early 19th century and by the 1820s the grape covered over 90 percent of South Africa's vineyards, where it was known as Wyndruif, meaning "wine grape".[1] It was once considered to be the most planted grape in the world, although this is no longer the case. In the 1950s, Chile's vineyards were made up of over 75% Sémillon. Today, it accounts for just 1% of South African Cape vines.[1]
