Slideshow: Sauvignon Blanc, Marlborough

There were not major differences between the organic and conventional Sauvignon Blanc in the first season of organic conversion, 2011-12. The organic block did show slightly less canopy growth and therefore required one less trimming. One of the most obvious visual differences in these photos is in the interrow. The conventional Sauvignon Blanc is completely herbicide-sprayed (including interrow) for frost protection as this is standard conventional practice at Wither Hills. The organic had a cover crop of Omaka barley sown in alternate rows in an effort to open the compacted soil and build soil organic matter.
