To produce the Cabernet Sauvignon “Aquitaine” Mount Barker Plantagenet, the separate parcels of fruit were destemmed into open and closed top fermenters without any chilling and then inoculated with selected yeasts. Throughout fermentation, phenolic extraction was carefully managed with a combination of hand plunging and pump overs twice daily which allowed for gentle extraction of flavour. The finished wine was left in contact with the skins for a further period at the completion of ferment to increase complexity and weight before being pressed to tank and racked to French barriques (30% new) for malolactic fermentation. Maturation then took place for a 17 month period before blending, filtration and bottling.
The Cabernet Sauvignon grapes for this wine are derived from two small block parcels of fruit from Wyjup, some 40km south-west of Mount Barker. Established in 1971, the vineyards are planted on north and north-west facing aspects at 200 metres above sea level, on deep gravel loam to light loam over quartz. The vines are hand pruned, shoot and crop thinned and leaf exposed.
The Plantagenet winery is located in the Mount Barker township, a sub-district of the Great Southern region in Western Australia. The area is famous for its premium quality, cool climate wine production, its proximity to the Southern Ocean ensuring the slow ripening of the grapes which enhances fruit composition and aromatic qualities. Plantagenet’s five vineyards are located to the south and west of the town.
