Barrel Fermented: Denotes wine that has been fermented in small casks (usually 55-gallon oak barrels) instead of larger tanks. Advocates believe that barrel fermentation contributes greater harmony between the oak and the wine, increases body and adds complexity, texture and flavor to certain wine types. Its liabilities are that more labor is required and greater risks are involved. It is mainly used for whites.

木桶发酵：表示葡萄酒经过小型木桶发酵（通常是55加仑的橡木桶），而不是大罐发酵。支持者认为，木桶发酵更有利于增进葡萄酒和橡木桶的协调性，增强酒体，提高酒的复杂性，质地和风味。不利是需要更多的劳工，并且涉及更大的风险。木桶发酵主要用于白葡萄酒。
