Variety recognition is paperwork with vines. Until a grape sits on the OIV international list, labels cannot legally name it as distinct — even if old Cape fields have grown it for decades.
winemag reports Mullineux’s long project — from a 1960 Swartland field mix through Vititec and SAWIS — culminating in OIV listing of Sémillon Gris and the world’s first officially certified planting at Roundstone. The mother block is about one hectare, from 2022. Selection work turned a mixed row into a named identity.
Mini-concept: Sémillon Gris is a pink-skinned mutation of Sémillon. For years it lived as folklore inside mixed old plantings. Official listing turns a curiosity into a named variety that can appear on a label without a legal shrug.
Why drinkers should care: a soda needs no paperwork. Naming a forgotten mutation makes wine legally itself. That is intentional identity — a glass that can say exactly what grape you chose, not a vague “field blend” shrug.
Hold the pattern: one certified hectare made the list real. A grape becomes real when the list finally says its name.
