Founded by brothers Theo, Alex, and Marcel in 1981, family owned Giesen Group of New Zealand  has been an industry leader for nearly four decades.  Based in Marlborough, the Giesen family  produces wine to be enjoyed at every occasion, from their highly awarded organic Clayvin Single Vineyard wines to the widely successful Giesen Estate wines range.
Since 2009 Giesen Wines has made a significant investment in organics, which by 2017 has 
resulted in 11% of the company’s Marlborough vineyards being Certified Organic with BioGro New Zealand. Whilst 11% of their vineyards are certified organic, they are committed to organics philosophy and culture throughout their entire viticulture programme with all of our fruit being sustainably grown.
