Grand Cru means fine wine, it expresses the Peter Seppelt estate's aim of producing the best, by virtue of a superior vineyard site which enjoys perfect elevation, and a wonderfully cool climate. All grapes are passionately tended at the Grand Cru Estate estate vineyard, to sustainable and biodynamic principles. Chemicals are used only sparsely, solely as a supplement to ecologically friendly critical foliar sprays, aerated compost tea and natural fertilisers. This provides valuable beneficial microbes which translate into a natural defense system within the plant, which then aids to envigor the vines. The Peter Seppelt principles of viticulture are fundamental for crafting exceptional fortified Barossa wines.
