A growing number of home winemakers and professionals agree that live liquid yeast cultures impart greater flavor to wine. And to make things even easier, our liquid cultures come in vials that can be added directly to the juice. Each vile contains sufficient living yeast to inoculate five gallons of must without rehydration or a starter propagation.
