All the grapes come from the Waterval Vineyard, on the Paardeberg, owned by Barry Schreiber and farmed by his daughter Franziska Wickens. This year, due to a huge increase in demand, Stompie outgrew the old vine block of the vineyard and looked toward new, dry-farmed, bush vines on top of the hill overlooking the old-vine Kweperfontein block. The old bush vines were planted in 1983 on decomposed granite and dry farmed since its initial planting with more recent block being planted in 2005. Since 2014, the vines have only received organic sprayings and the undervine work has been done purely by machine/hand and not chemically.
The grapes were hand-harvested starting in mid-January into small lug-boxes, limiting the damage to the grape in larger bins. They were harvested at different sugar levels to insure good pH and acid from the early picking with powerful structure and aromas from riper batches. The majority of the grapes were whole-bunch pressed with full lees to stainless-steel with about one-third of the grapes being destemmed and fermented on their skins for a month, prior to being pressed to stainless-steel. Fermentation occurred naturally and at cooler temperatures (57°F) without any additions and after seven months of aging the components were blended to tank and settled naturally. The wines were bottled in September without fining, filtration or a sulfur addition.
