Portfolio Winery is a joint venture between husband and wife Geneviève and Luc Janssens; all the operations for this winery are conducted in their “garage” located next to their home. The term for this type of winery is “garagist”. We have visited a number of “garagist” wineries over the years in the Napa Valley as select cities within the county allow the use of a residential garage for commercial wine making purposes. This is the finest and most functional garage winery we have seen in the Napa Valley.
