In the heart of the world-class Wairau Valley, we source our fruit from sub-regions selected for the distinct characteristics each location brings to the wine.
These vineyards enjoy bright, cool climatic conditions that promote a long, slow ripening period and intensified flavours. Careful yield control then guarantees exceptional fruit from one of the globe’s finest sauvignon blanc regions.
Sauvignon Blanc grapes from the Lower Wairau sub-region provide rounded, mouth filling fruit weight and contribute ripe, tropical, pineapple and guava characters to our blend due to the climate, geography and soil profile of the area.
Geography: The Lower Wairau is a very small sub-region positioned between the Blenheim Township and the north eastern coast of the South Island. The flat terrain and coastal influence on the Lower Wairau make this a highly desirable sub-region for growing Sauvignon Blanc.
Climate: The area is bright and warm, with an average of approximately 1,300 growing degree days per year. Given the proximity to the coast the temperature range is less extreme than other sub-regions of Marlborough, however the long ripening period experiences a notably diurnal temperature pattern. Rainfall in the sub-region is generally very low as any rain is directed along the Richmond Ranges, or out from the east coast by the Wither Hills.
Soil: The soil profile of the Lower Wairau generally features river gravels well below a deep, nutrient rich layer of silt topsoil which has been collected from further upstream and deposited by the Wairau River as it has meandered over the valley over thousands of years.
The Central Wairau was one of the earliest established vineyard sub-regions in Marlborough. This sub-region produces fruit with the passionfruit, gooseberry and boxwood characters typically associated with Marlborough Sauvignon Blanc.
Geography: The Central Wairau sits between Renwick and the Blenheim Township in the heart of the Wairau Valley. This area is a flat river plain which gradually tightens to the
Climate: The proximity of the Wither Hills to the south and Richmond Ranges to the north result in generally warmer and wetter conditions than the Lower Wairau. This average wind run in the Central Wairau is less than the Lower Wairau due to the distance from the coast.
Soil: The soil profile in the Central Wairau sub-region varies from north to south as a result of the Wairau River washing the topsoil along the valley towards the eastern coast and depositing it in the Lower Wairua sub-region. Most of the Central Wairau has a free draining soil profile characterised by a thinner layer of nutrient rich topsoil than the Lower Wairau, and river gravels close to, if not visible on, the surface.
The Southern Valleys sub-region produces Sauvignon Blanc grapes which are crisp and fresh with balanced acidity. On the palate this fruit has a sophisticated structure is balanced by ripe stone fruit and citrus flavours and aromas. The Southern Valleys sub-region provides elegance and length to the Mohua Sauvignon Blanc blend.
Geography: The Southern Valleys are tight valley formations running south to north out of the Wither Hills and into the main Wairau Valley plain. Each valley has unique characteristics, but the features these all share are that they were glacial formed and have gradual gains in altitude towards the south ending with north facing slopes at the base of the Wither Hills.
Climate: This group of valleys generally experience a cooler and drier climate than the main Wairau Valley. The valleys are generally protected from rainfall which is diverted off the east coast or hugs the Richmond ranges when coming up the west coast. The sub-region experiences a significant diurnal weather pattern which provides intensity and concentration to the fruit.
Soil: The soil profile can vary from valley to valley, however the soil generally features a layer of silt topsoil with a significant influence of clay, and river gravels below.
