(Reuters) - Organic, biodynamic and sustainable are words being used to describe wines but the eco-sounding terms have little impact on wine lovers.In a survey of 1,000 consumers by global consulting firm AlixParnters eco-friendly was rated the least important attribute for wines, while price topped the list.Most European producers, who operate in a strictly regulated market, do not use organic or biodynamic on their labels because they say the paperwork is complicated and the fees for certification are onerous.
