Six years after working on the completion of a state-of-the-art fermentation barn for Nickel & Nickel, a premium single vineyards wine producer in Napa Valley, LeDuc & Dexter, Inc.’s commercial plumbing department is helping to complete a carbon copy of the original barn right next door.

The overall design/build project includes A 30,000 square-foot subterranean barrel cellar, capable of holding up to 3,200 French oak barrels, which is situated underneath both fermentation barns. 

The barrel cellar was built along with the first fermentation barn and a parking lot existed next to it until construction began and the concrete lot was saw cut to uncover the cellar roof upon which the second barn was built.

LeDuc & Dexter tied in all of the plumbing for the new barn into the original plumbing of the first barn as part of the design/build plan from six years ago.  The barrel cellar roof contains a radiant cooling system installed by LeDuc & Dexter.

LeDuc & Dexter installed hot and cold water, nitrogen, air,
heating hot water and chilled water supply and return lines in
the tank pads before the concrete cover is poured over it
to form the pad surface where the wine tanks sit

Ledcor is the general contractor on this expansion project.  Nolan Construction completed the first phase six years ago.  An element of continuity was provided by Mitch Hamilton, the project superintendent, who has worked on both phases for both companies.  The project is now nearing completion.

The wood-frame fermentation barns have been assembled using age-old techniques of hand-joinery for post and beam construction that were common in the 1880s. Yet the barn houses a modern winery equipped to custom make the wine from each individual vineyard.

All of the plumbing and utilities are hidden from sight in the fermentation barns.  The tank pads are hollow, containing most of the plumbing lines installed by LeDuc & Dexter.  All of the other pipes and wring are concealed behind the wooden walls creating a stylish showpiece for winery visitors to enjoy along with the world class single vineyard wines produced by Nickel & Nickel.

is the two hose stations in the foreground since all
of the plumbing pipes are hidden in the tank pads
