Launches and celebrations at the venerable Rietvallei estate outside Robertson are always specials events, memorable for Burger hospitality at one of the valley’s most historic estates. Close family loyalties combine with a fine winemaking tradition going back six generations to 1864 and the results can be as fascinating as proven by this multi-faceted sauvignon blanc.
For many years sauvignon blanc has formed the core of the estate’s wine production, and this barrel-fermented star is the first single cultivar wine in the Esteanna range which was launched in 2009. Previous white vintages saw unwooded sauvignon blanc blended with barrel-fermented chardonnay, chenin blanc and even viognier, with the 2017 blend garnering Veritas Gold at the 2018 contest.
CEO and winemaker Kobus Burger realised the potential of the 2018 harvest early and decided to add a new and wooded sauvignon blanc to the farm’s four ranges of this popular varietal. He used juice from vineyards occupying various unique locations on the estate, including alluvial soils on the Breede river banks and red calcareous soil on the south-east-facing slopes. After harvesting, free-run juice was selected and settled for three weeks before being racked and transferred to steel tanks. The must was then moved to second-fill French oak and fermented dry. After nine months and after regular batonage, the wine was stabilised , fined and bottled without filtration.
This is a big wine, presenting an array of aromas ranging from passionfruit to citrus, green fig and little green pepper. These are followed by a complexity of flavours, lent crispness from acidity and agreeable backbone from the oak. A touch of cream adds to the nice balance of a serious sauvignon, which can pair more than seafood with panache – think of classic French poultry dishes, especially rich versions like chicken with morels and cream from the Jura region.
The alcohol levels are held at just over 14% and the retail price is around R185.
