Our Mason Sauvignon Blanc is from a single vineyard called Blockhouse in Yountville, a growing region well suited for producing elegant Sauvignon Blanc because of its cool evening maritime influence and warm days. Located in the heart of the valley floor, we’ve hand selected fruit from this block for over 20 years- leafing the morning side for mottled light, leaving the afternoon side shaded to protect from burn. 100% Sauvignon Blanc, Mason Sauvignon Blanc has long been heralded for its varietal trueness and exemplary balance. After its lengthy, cold fermentation in 100% stainless steel tanks, a portion of the blend is barreled down into stainless steel barrels and scattered with the fermentation lees. These barrels undergo batonnage, stirring the lees three times weekly for over 2 months until it is blended back with the main lot.
