This review collates the scientific literature regarding organic and biodynamic wines. It concerns techniques that allow organic or biodynamic wines to be distinguished from conventional products. Other aspects of the organic wines addressed include the antioxidant capacities and the content of compounds potentially toxic to human health, like metals, such as copper, deriving from treatments in the vineyard, or ochratoxin A and biogenic amines. Organic wines, in which, unlike non-organic wines, the SO2 must be lower or absent, may undergo premature ageing and present high levels of oxidation compounds. Some authors used selected indigenous yeasts to reduce the production of these molecules and improve the organoleptic quality of the wine. Also, the effects of biodynamic viticulture practices on the chemical and sensory characteristics of wines are compared with other conventional or organic products. With the growing market interest, differences among conventional, organic and, moreover, biodynamic wines, require more in-depth analysis.
