Established by Bob and Cherie Berton in May 1996. 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.
2019 was a challenging climatic season, with warm and dry conditions persisting throughout the growing season. However, hail and high winds in November resulted in a very low yielding vintage. The low crop level meant ripening occurred early for the region, with harvest taking place in the middle of March. The fruit showed excellent quality, despite the challenging weather conditions during the 2019 vintage.
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.
The Shiraz was picked in late April; the grapes were destemmed and crushed into 15 tonne static fermenters where it was inoculated with carefully selected yeast. Fermentation continued for six days between 22°C and 28°C on premium French untoasted and toasted oak. The wine was then pressed at 0.5 Baumé into stainless steel storage tanks and left to ferment until dry. It was then racked into stainless steel storage for malolactic conversion. Once complete, each parcel was clarified via centrifuge and transferred into new and used French and American oak barrels for 12 months. The best barrels were carefully selected and blended prior to bottling.
The Bonsai impresses with impenetrable violet hues and delivers intense aromas of blueberry, plum, liquorice and toasty oak. Subtle fine tannins marry perfectly with the soft, elegant palate of dark cherry, plum and white pepper.
