Langhorne Creek is quite unique, as it continues to enjoy winter flooding of the Bremer and Angas Rivers to irrigate some of its vineyards to this day. The floods emanate from the rainfall in the Mount Lofty Ranges, between Mount Barker and Callington, and also deposit rich alluvial soil and nutrients onto those vineyards within the flood plain. Langhorne Creek receives an average winter rainfall of just 380mm per year and flood events provide enough moisture in the rich deep soil profile of the flood plain to carry vines in these areas through the dry summer months. The majority of the vast vineyard plantings of the area use modern and efficient drip and sub-surface irrigation practices to maintain the water needs of the vines. Access to water, coupled with cooling breezes from Lake Alexandrina that reduce evening temperatures and provide mild even growing seasons, help make Langhorne Creek an ideal wine growing region.
