The Grandfathers Block on Hill of Grace was established by Nicolaus Stanitzki in the 1860s. These vines were planted on own roots from pre phylloxera material brought by early European settlers. The sturdy, gnarled vines are dry grown and yield an average two tonnes to the acre, widely spaced at 3.1 metres between vines and 3.4 metres between rows. The one metre high trellis consists of two wires which carry two to three arched canes, yielding bud number of around 40% to 50% The foliage is allowed to hang down to form a drooping canopy, thereby reducing shoot vigor for enhanced intensity. In wetter years, the shoot tips are trimmed before veraison on the blocks showing any increase in vigor.
