Gladstone Vineyard has an established reputation as a quality boutique wine producer, making award-winning wines of finesse and complexity. The vineyards are planted along the river terraces of the Ruamahanga River, which has a unique free-draining soil profile of clay over stony silt loams. The microclimatic conditions are semi-maritime, which experiences very cool springs, extended sunshine hours and high exposure to UV light, which provides ideal conditions for ripening.
