Lone Wolf is Mission (aka País, aka Misíon) and various mutations and crosses of the variety from the Lone Wolf Vineyard, planted in 1896 and abandoned for many years. During this period without pruning or upkeep, the Mission vines interbred with each other and with various other local non-vinifera varieties. The grapes were harvested by hand and destemmed into a stainless-steel tank, where they macerated on the skins and fermented for three weeks with one punchdown by hand each day. The juice was transferred to used barrels to age. Bottled without fining, filtering or added sulfur.
