Concept. Sombrio is a wine that is made avoiding contact with light. Most white wines are vinified avoiding contact with oxygen, to prevent oxidation, but this also occurs due to exposure to light. From harvesting, through winemaking, racking and bottling, all processes are carried out at night, with as little light as possible. The bottle is also quite opaque, so the wine is only exposed to direct light when we serve it in a glass… unless we do it in the dark!
