(Philly) - Buzz: Hey Marnie, I saw a wine bottle in the store yesterday that said it was made from organic grapes. Why not call it organic wine? Marnie: Because they mean different things, Buzz. Grapes grown naturally, without chemicals like fertilizers and pesticides, have been shown to make better wine. They have an inherent advantage in quality potential, flavor and a wine's ability to age gracefully. Organic winemaking is far more problematic; it creates a major quality control issue that leads to an inconsistent product and premature spoilage. Most vintners who go organic choose not to certify the wine itself as organic because doing so would require them to skip an essential winemaking step: adding sulfur to prevent oxidation and spoilage.
