“Theorem Vineyards is a quest as much as it is a winery, driven by a search for truth. With the loving restoration of our historical 1800s Diamond Mountain estate, we seek to uncover the truth of the land through wines that capture the beauty and spirit of this magical place.” – Kisha & Jason Itkin
