The 120 acre Koonowla vineyards are in the geographical region of the Clare Valley, lying Latitude 1380 43’ 02.01” East and Longitude 340 03’ 15.28” South, at approximately 300 metres above sea level.
The climate is described as Mediterranean with four distinct seasons, Summer, Autumn, Winter and Spring and an annual rainfall of 21 inches (535mm) falling mainly between May and November. The winter temperatures can drop to 0 degrees C on the low alluvial flats and in summer will sometimes rise up to 40 degrees C but often with cool nights and cooling Valley breezes slowing the ripening fruit, giving the fruit its distinctive Clare Valley flavour profile.
The vineyards are planted on undulating hillsides with terra-rossa soils in 19 different blocks with interconnecting and surrounding compacted roads for improved management and fire protection.
Blocks subject to frost have wind-fans installed which are automatically controlled by temperature sensors ensuring Koonowla has frost protection to provide consistency of fruit yield and quality.
Koonowla is fortunate to have a significant aquifer of underground water that it uses to supplement a catchment dam collecting runoff from its higher grazing country. The Vineyard is equipped with drip irrigation using computer controlled systems to ensure that no water is wasted and is targeted to the vine only. We only irrigate to maintain canopy health and to protect the fruit from sunburn and aid ripening.
The principal Clones used are:
• Cabernet Sauvignon 125, CW44, LC10, LC14 and LYNNS
• Shiraz 1654, BVRC12, NSW15
• Riesling 140, D2V2
Koonowla practices sustainable agricultural practices and where possible uses straw and composted mulch to help retain moisture and add nutrients and build organic carbon into the soils.
