The Block 6 vineyard faces east and rows run north-south with significant undulation. The vines are cane pruned with the canes wrapped onto the top wire of the low lying trellis. The present 1.5 hectares comprises a corner of red loam, some heavy clay in the middle of the block and gravelly alluvial soils on the lower side. The underlying ‘South Maslin Sands’ geology is extremely complex containing layers of glauconite, limestone, sandstone and siltstone.
In 1984, Colin Kay first made Block 6 Shiraz as a single vineyard wine. From the first vintage, it stood out for its depth, structure and complexity and quickly earned a reputation as an exceptional expression of McLaren Vale shiraz.
