The Opou vineyard, originally planted in 1969, has rich Waihirere silt loam soils that nurture the roots of the Chardonnay and Riesling planted within. A hedge of Navel oranges runs through the centre of the vineyard, ‘sharing of astrality’ it is said, and perhaps allows the Riesling to evoke aromas of citrus blossom and higher ethers.
