M.P.H.S. 2018
The pinnacle of the range is the Alto MPHS, a flagship release made in tribute to the estate’s previous winemakers, whose initials make up the name. Produced only in exceptional vintages, this exclusive blend 50% Cabernet Sauvignon & 50% Cabernet Franc encapsulates the thread of family, tradition and quality that has run through Alto for close on a century.
Vinification
The Cabernet Franc grapes were hand harvested at 24.5 Balling in March 2018 and the Cabernet Sauvignon grapes at 24.8 Balling in late March 2018. Grapes were vinified separately and fermentation took place in stainless steel tanks at 25 to 27 C. The pump over method was used to ensure maximum extraction of colour. The wines were pressed after 18 days. After malolactic fermentation it was racked off the lees, the Cabernet Sauvignon component was in 100% new French oak barrels and the Cabernet Franc was in 100% 2nd fill French oak barrels for 18 months. The wine was blended without fining and received a light filtering before it was bottled in early 2020. Total quantity produced 1693 bottles.
