As small family artisan winegrowers, the Milltons are the first New Zealand vineyard to gain Bio-Gro certification for organic wine production in 1989 as well as becoming New Zealand's first biodynamic vineyard.\r\rOpou Vineyard is an old vineyard planted with a mixture of Chardonnay selections. Hand-picked grapes were gently pressed with the resulting juice being put into small French Oak barrels where they waited until the fermentation started in its' own time. Only 12% of the oak was new however 100% of the wine enjoyed the secondary malo-lactic fermentation to soften the palate and increase texture. For over 12 months the wine aged in oak, then was assembled in stainless steel tanks to rest before being bottled on the property. James and Annie Millton established their winery on the banks of the Te Arai River, near Manutuke in 1984. Located on the East Coast of the North Island of New Zealand in the winegrowing region of Gisborne, this was the site where early settlers first planted grapevines in 1871.\r\rMillton was the first producer in New Zealand to attain BioGro certification for organic wine production in 1989. Having practiced traditional methods of cultivation and production centred on biodynamic principles since inception, Millton was the first winegrower in the Southern Hemisphere to gain the biodynamic certification Demeter in 2009.
