"The first Springflat came from our winery block vineyard. It is approximately 2.5 acres, sits on quartz buckshot clay soils and its production is around 2 tones per acre. Planted in 1988, it has now reached maturity and is capable of producing fruit of incredible depth of flavour. Its position protects it from wind, thus creating frost susceptibility. In years of frost, the leaf to fruit ratio is dramatically increased, thus producing wines of exceptional intensity, which led to the discovery of the Duck Muck.Since then, several other vineyards on exceptional sites scattered across the Heathcote region have produced that has made it into the Springflat. By enlarge, these vineyards are 12 years + in age and are dry grown on the Cambrian volcanic soils of the southern part of the Mt Camel range. These vineyards are run to our discression, cropping less than 2 tons per acre, producing complex flavours only their particular sites can, which enables the Springflat Shiraz to broaden in complexity and reliability. Matured in 45% new French and American hogsheads for 15 to 18 months. Recommended to be consumed up to 12 years from release. No filtration. Closed under premium cork or screw cap at the Standing Order Customer’s discression. Approximately 1800 cases made annually."wildduckcreekestate.com
