Demand for organically grown crops has increased exponentially in the last few decades. Particularly wine sector, organic and biodynamic management systems are gaining more importance, with some of most prestigious wineries converting to or viticulture. The purpose this study was review evidence comparing effects conventional, organic, viticulture on soil properties, biodiversity, vine growth yield, disease incidence, grape composition, sensory characteristics, quality. Only studies representative field replicates a number samples were included. Soil nutrient cycling enhanced under viticulture, especially after conversion completed. Cover crop mixtures used, compost application, absence herbicides might be factors that account higher biological activity biodynamically managed soils. Seventeen out 24 observed clear increase biodiversity different trophic levels. Plant protection regime cover mainly determine Organic treatments showed 21% lower 18% yield compared conventional decrease not correlated level A moisture content physiological performance (assimilation rate, transpiration stomatal conductance) is likely responsible respective systems. Juice total soluble solids concentration did differ among No overall differences berry composition juice quality could observed. By describing hypotheses concerning meta-analysis provides helpful guidance defining further research agriculture perennial, but also annual, crops.
