Barton's vineyards at latitude 34 degrees south are some eleven kilometres from the South Atlantic coast in the wine ward of Walker Bay. Planted on the south slopes of the Kogelberg mountains 190 metres above sea level they absorb the cooling sea breezes from Walker Bay. The frost free, cool climate and southerly aspect induces a slow and extended grape ripening period and consequent good colour and tannin formation for the red wines and concentrated fruit and acidity for the white wines. The sub soil is gravelly sandstone interspersed with quartz, ironstone and clay.
