Clare Valley, fine wine region in south australia with a strongly continental climate: warm summer days and cool nights. This combined with differences in soil, elevation, degree of slope and aspect, enables the region to produce some of Australia’s finest Riesling as well as excellent Shiraz, Cabernet Sauvignon, and Malbec. While wines are sturdy and powerful, alcohol levels are generally lower than those of the Barossa Valley or McLaren Vale. There are 40 producers, of which 15 sell but do not make wine there.
