Roberta de la Mota, the winemaker, selects the best parcels of Malbec, often from older vines, from selected vineyards dotted around the Mendel Estate. Average age of the vines is 45 years old. Harvesting takes place based on analysis to determine full phenolic ripeness. The grapes are hand picked, sorted and 100% destemmed. Manual berry selection at the sorting table. Fermentation and maceration take place in a mixture of concrete and 80-hectolicter tanks. Daily manual pigeage during the ferment for almost 2 weeks, then rackewd into new and used American and French oak. 12 months ageing in oak, with minimal filtration prior to bottling.
