Mike Anderson’s family moved to Napa Valley in the early 1980’s to pursue their own winemaking careers by founding Anderson’s Conn Valley Vineyards, Trespass Vineyards, Ghost Horse Vineyards and Eagles Trace.
MTGA officially stands for “Michael Todd Gustaf Anderson”, though some more clever acronyms have been revealed over the years. At less than 1,000 case total production, MTGA Wines pays homage to the four generations of the Anderson family who have worked in the Napa wine industry.
In 2010 Mark realized that despite being a part of the winemaking process in many facets, he never made wine from start to finish without guidance. So, with a picking bin in the back of a pickup track, a set of pruning shears, picking lug, and some spare time he hand harvested his first batch of Merlot grapes. In the fall of 2011 he met his future wife and “HBIC” Brittany. A year later the couple bottled their first vintage of MTGA Merlot which was released in the winter of 2013.
