British born Jack Roberts met Johanna Jensen on his first day arriving in Napa. 10 years later, happily married; they are producing wine together under the Keep Wines brand. Jack and JJ are dedicated to creating wines influenced by the old world with minimal manipulation and great potential ageing. Jack worked for many years as Steve Matthiasson’s assistant winemaker. He follows in Steve’s steps with his dedication to sustainable, regenerative farming and low intervention winemaking.

Today, Johanna and Jack Jensen are making some of the most exciting wines in California and we're thrilled to share this single vineyard blend from the Lost Slough Vineyard, right next to the Sacramento River Delta, hence the name. Native yeast fermentations, no fining or filtering, giving a clear expression of the place. White flower aromatics, clean stone fruits and great mineral-driven acidity. 50% Gruner Veltliner, 25% Chardonnay, 25% Pinot Gris.
