Sustainability. While some may regard it as a bit of a buzzword, both the concept and style of farming/viticulture have been seriously embraced across our wine industry. The Sustainable Winegrowing New Zealand certification programme (SWNZ) had its inception in 1995 and New Zealand Winegrowers figures show that currently 96% of New Zealand’s producing area is SWNZ certified, with goals for the industry to be zero waste to landfill and carbon neutral by 2050. New Zealand Winegrowers promotes focus across six key sustainability areas: climate change, water, winery waste, plant protection, soil and people. One example of this is in water management promoting initiatives for conserving and reducing water usage, while some wineries recover/recycle winery wastewater. Another is winery waste as wineries generate a huge amount of organic matter in the form of grape stems, pips and skins. Already common in biodynamic wineries, more and more are composting this grape marc, with others converting it into stock food. Soil health is another key area - from the reduction of chemical inputs, reducing erosion through the use of cover crops, along with no or low tillage regimes to combating soil compaction through to the use of drones for spraying, all of which can contribute to biodiversity and healthy soils. An example of this is Greystone winery in North Canterbury, which has run its High Wire Trial Project in regenerative farming for the last three years, increasing the height of its vine canopy, allowing it to run sheep in the vineyard year round. Having its four-legged weed eaters on the go has allowed the winery to minimise tractor use and mowing with both a significant reduction in its carbon footprint and a healthy monetary saving in diesel. This minimal tillage approach along with an ongoing supply of natural, organic ovine fertiliser helps to improve soil structure and foster a thriving microbiome, while a diverse mix of pastures attract beneficial insects and contribute to natural pest control. The initiative has been a real farm to table one too, with the lamb featuring on the menu in the winery’s restaurant. All in all it has encouraged Greystone to extend the project to 25% of its vineyard. 2022 Greystone Organic Waipara Chardonnay Price: RRP $55 Rating: Outstanding Leads with a touch of gunflint, toast, citrus, white peach, minerally, complex and fascinating nose that draws you in. Creamy texture, mouthfilling, somehow feels effortless, beautifully integrated, nothing out of place. An undercurrent of citrus and saline influences with fabulous length. Very smart wine that draws you back, already drinking superbly but potential, too. www.greystonewines.co.nz 2023 Greystone North Canterbury Pinot Gris Price: RRP $32 Rating: Excellent The nose leaps out of the glass, white flowers/florality, stonefruits, nutty aspects, lemon verbena perhaps with time. Good volume in the mouth, rich, mixing notes of apricot and nectarine while again bringing in those nutty elements. Fruit sweetness with fruit cordial notes yet appealingly dry and crisp on the finish. This just works, great appeal. www.greystonewines.co.nz 2019 Greystone North Canterbury Pinot Noir Price: RRP $29 Rating: Excellent to Outstanding Nutty, chestnut, delightful fragrance, cherry, roast beetroot, savoury/umami notes, refined oak. Mouthfilling, deep, almost brooding, lead pencil/pencil shavings, chopped herb, dark fruits, spice, fine tannins, the savoury qualities begin to grow on the palate. Complex, elegant, with air the tannins build as does a truffley note. Delightfully complex. www.greystonewines.co.nz
