Springfield Estate Wild Yeast ChardonnayTrue to its moniker, the Wild Yeast Chardonnay is fermented using the native, wild yeasts that occur naturally on the skins of the grapes. Unwooded, it is fermented in underground cement tanks in a slow, volatile process that can take anywhere between 6 9 months. This method, although risky, results in incredibly expressive wine with a wisdom that is unattainable in wines made using commercial yeasts. Can be enjoyed for the next 3 4 years. Bottle
