Regrettably, this is the last vintage of The Derivative that will contain Semillon from Monte Rosso.  Gallo is no longer interested in selling fruit to other producers.  But not to worry.  In 2016, we secured a new source of top-flight Semillon from Rossi Ranch.  Along with the Muscadelle from Pagani Ranch and the Colombard, Muscadelle, and Palomino from Mancini Ranch, The Derivative lives on!  As usual, the Semillon was fermented in a mix of old, neutral oak and stainless.  The other components were done in stainless.  No malolactic fermentation to preserve acidity and freshness.  Filtered but not fined.
