The grapes for the wines that carry the Mt Difficulty Bannockburn Estate label are subject to two strict criteria: they are managed by our viticultural team and must be sourced from Bannockburn vineyards - the south side of the Kawarau River in the southern Cromwell basin. Each has a specific terroir, largely influenced by climate, and offers a variety of soil types from open gravels to heavier clays. Mt Difficulty Bannockburn Estate Pinot Gris is blended from seven of our Bannockburn vineyards: Templars Hill, Long Gully, Bannockburn Bay, Ferris, Lytefoot, Swansong and Pipeclay Terrace. Templars Hill, Pipeclay Terrace, Swansong and Lytefoot have a combination of heavy Scotland Point clay soils alternating with the drought prone coarse gravel Bannockburn soils. Long Gully consists of Lochar soils, which are well-drained, high pH soils ideally suited to viticulture. Ferris and Bannockburn Bay are the result of dune formation from parent material blown across the river from the Cromwell flats. They are very low in both fertility and water holding capacity.
