This is an elongated region, running east to west from Montagu to Oudtshoorn. The climate is one of extremes with warm summers and lower rainfall. Vineyards tend to be planted in river valleys where water for irrigation is plentiful. The Little Karoo produces some of South Africa's most renowned fortified wines. Also worth a look is Chenin Blanc, as this grape's naturally high acidity and fruitiness make it particularly suitable for warmer areas.
