Thank you for replying...the measurements we took were straight from the grape, we are having them delivered and to start the crush this weekend. We have a neighboring winemaker refer this crop to us, but warned of the high sugar content. The grapes do no appear to be over ripe, our concern was controlling the sugar...we took for a given the alchol may be high. We typically use Lalvin but were recommended to try Vintener's Choice Zin. This will be a substantial inventment for use and wanted a second opinion.
