At Gladstone Vineyard, we are committed to growing our vines and producing our wine in a thoughtful and environmentally responsible manner. We like to call this "intelligent winegrowing". It means making smart, considered decisions about everything we do, with the interests of the land, the vines and the wine top of mind.
Our philosophy is that a healthy vine will produce healthy, quality grapes – and premium wine. To that end we put considerable effort into achieving soil and plant health. We meet or exceed the Sustainable Winegrowing New Zealand programme standards in all our practices and are guided by biological and organic principles. This includes:
- growing grasses and wildflowers between rows of vines to increase biodiversity, improve soil structure and nutrients and encourage beneficial insects and soil microorganisms
- managing undervine weeds with our undervine mower
- mowing the grasses and wildflowers at key times of the year with our side discharge mower leaving a thick layer of mulch under the vines – and grazing sheep and pigs at other times
- applying organic liquid biological cultures to the soil and vines during growing season
- using our flame weed killer around the grounds to reduce the need for herbicides
- composting our grape pressings
- aiming for minimal intervention in the winery in terms of additives and processes wherever possible – allowing the wine to clearly express the terroir
- using natural yeast for our Gladstone Vineyard Pinot Noir fermentations.
