Winemaking
Thoughtful & Classical
There is no set “house style” or single winemaking recipe at COLLATERAL. Winemaker Mike Hirby draws upon decades of experience to respond with a deft hand to what each harvest brings. Our cellar practices include extended aging in puncheon, barrel fermentations, and partial whole-cluster fermentations, depending upon the vintage. We craft vineyard-designate wines that are texturally elegant and freshly aromatic in their youth, and poised to increase in complexity with cellar age.
One thing that’s integral to our approach: We are draconian in our selections. We bottle only the finest barrels, from the best vineyard blocks.— Mike Hirby, Winemaker
Our Wines
The Pledge
Our finest offering at COLLATERAL is a promise of continuity to all who have supported D. R. Stephens Estate over the years, and a promise of excellence to all those who have joined our community more recently. COLLATERAL’s “The Pledge” Napa Valley Red Wine continues a decade-old tradition of bottling a top barrel selection in only the very best vintages—in fact, we originally named this wine COLLATERAL, in reference to a memorable childhood conversation between Justin and his dad. We only release “The Pledge” when the vintage justifies it, so quantities are limited. Become a Member to ensure access to this rare wine.
