There’s Heitz Cabernet, and then there’s Lot C-91. Heitz describes this historic cuvée as a qualitative step above its flagship Napa Cabernet, built exclusively from the estate’s single-vineyard holdings across western Oakville, eastern Rutherford, southeastern Howell Mountain, and the foothills of St. Helena. It’s Heitz taking everything it knows about Napa Cabernet and raising the stakes. Joe Heitz understood the power of place better than most, but he also knew great vineyards didn’t always have to stand alone. In 1969, he began selecting Cabernet from exceptional parcels, believing their individual strengths could become something greater together. That idea became Lot C-91, a wine defined not by a single vineyard, but by the careful assembly of some of Heitz’s most compelling Cabernet. The same philosophy carries into the cellar, where each parcel is given time to reveal its potential before the most expressive barrels are chosen for C-91. The 2019 has now had several years in bottle for those pieces to come together, adding another dimension to a wine built for complexity and longevity. With 97 points from James Suckling and a $99.99 price, this is a particularly good moment to discover what C-91 is all about.
