The grapes used to produce the Shiraz Cabernet Bonsai Berton Vineyard were fermented in stainless static fermenters for approximately eight days at temperatures of between 22°C and 28°C on premium French untoasted and toasted oak. The grapes were pressed at 0.5 Baumé into stainless steel tanks and fermented until dry. The wine then went through malolactic fermentation and each parcel was clarified via centrifuge. Each parcel was transferred into new and used French oak barrels for approximately 20 months. The best parcels of each of the Shiraz and Cabernet Sauvignons were carefully barrel selected.
The vineyard was planted in 1996, with vines planted 1.5m apart and with 3.3m between the rows. A single wire trellis system is used which ensures good ventilation and minimal disease. The canopy is typically quite sparse allowing maximum sunlight penetration. The vines are spur pruned and grown in “Podsolics” an old grey soil formed over yellow clay, which is sandy and slightly sodic.
Established by Bob and Cherie Berton in May 1996, Berton Vineyard is one of the most important wine producers in Australia. The estate covers 30 hectares of land located on gently rolling hills at 450 metres above sea level, in a subregion of Eden Valley in South Australia. The superb Reserve Shiraz and Reserve Chardonnay wines are still sourced from this plot. In 2007, Bob purchased the Yenda winery in the heart of the Riverina. This state-of-the-art facility has the capacity to process 20,000 tonnes and enables Berton Vineyard to produce value for money wines which sit alongside their premium single-vineyard offerings.
