Natural wines are made using minimal intervention in the winemaking process. This means that the grapes are typically grown without synthetic pesticides or fertilizers, and the fermentation occurs with native yeasts found on the grape skins. The goal is to produce a wine that reflects the true characteristics of the grapes and the terroir, or the environment in which they are grown. These wines often have a unique taste and can vary significantly from bottle to bottle. Natural winemakers may also avoid additives like sulfites, which are commonly used in conventional wines to preserve freshness. As a result, natural wines can have a more complex flavor profile and may appear cloudy or have sediment.
