The grapes used are pretty much standard vinifera varieties. Reds included both cabs, petit verdot, merlot, and surprisingly some were growing nebiolo and tempranillo. Very few hybrids were being grown. A few vineyards were growing Chambrocine but that was about the extent of hybrids.
Since most of the grapes were vinifera, most of the trellises were VSP type. I got pics.
neat vineyards, lotsa grapes

The owner said that his land was fertile enough for each vine to handle 4 arms instead of 2. The lyre arrangement supports this in a VSP arrangement
