"Wines with “estate bottled” designations must: (a) also designate an appellation of origin or an AVA, and both the vineyards and the winery must be located there; (b) the grapes must come from vineyards owned or controlled by the winery; and (c) the wine must have been produced, from crush to bottle, in a continuous process without leaving the winery’s premises."
