The show start with a visit to Napa Valley's oldest wooden, gravity-fed winery, home of Trefethen Vineyards. At the site, our master carpenter meets plumber George Biter, who shows his rough work, including ABS and cast iron piping. General contractor Jim Nolan describes how a large laminated-veneer-lumber beam was hoisted into place, spanning the new kitchen and precluding the need for a mid-room support post. New French doors go into the west wall of the old dining room, and our host visits the Palo Alto factory where the energy-efficient plastic film inside the glazing is made. Back on site, we check out the foundation plantings that are threatening Dennis's house, and take a look at Dennis's little vineyard. Then it's off to the other extreme of the winemaking art: Opus One, a joint venture between the valley's Robert Mondavi and France's de Rothschild family.
