Breaking Bread Zinfandel 2018. Redwood Valley, Mendocino County, Natural Wine. Fruit for this Zinfandel was treated to whole-cluster, carbonic maceration. After that, the primary and secondary fermentations proceded with ambient cultures, and the wine spent seven months in neutral French oak. It was bottled un-fined and unfiltered.I found the Zinfandel’s flavor profile to be nearly identical to that of the Grenache, albeit a shade more blue-fruited, its black-raspberry midsection amped with a confectionary of carbonic.
