Organic wines are produced from grapes that are grown according to organic farming principles. Although there are differences and disagreements in the definition of what constitutes organic farming, in general terms it means excluding artificial chemicals such as pesticides. Such artificial chemicals can end up as residual contaminants in the wine itself and may be harmful to health. This is one reason for the increase in demand for organically produced wine.
Aside from the more natural means of production and absence of artificial chemicals, consumers choose organic wine because of its taste and purported health benefits which can include a lowered risk of heart disease and stroke and a range of other advantages.
