Grape

Camminare Noir

Camminare Noir is a red hybrid grape released by the University of California, Davis, in 2019. Its breeding addressed Pierce's disease, a bacterial disease that can kill susceptible vines. It belongs to a generation of wine grapes intended to combine resistance with fruit suitable for contemporary winemaking, and commercial bottles now extend the story beyond trials.

Resistance and ancestry

Andrew Walker's breeding programme used resistance from Vitis arizonica and repeated crosses with Vitis vinifera. Foundation Plant Services records Camminare Noir as approximately 94% vinifera, with Petite Sirah and Cabernet Sauvignon contributing substantial parts of its ancestry. That ancestry reflects a multigeneration pedigree; they do not mean the variety is a simple Petite Sirah × Cabernet Sauvignon cross.1.

Its selection number was Walker 07355-075. It should also be distinguished from Caminante Blanc, the similarly named white variety released in the same group. Camminare Noir's identity is separate from the other red releases, Paseante Noir and Errante Noir.

What the trials establish

The Davis profile reports strong Pierce's disease resistance in repeated greenhouse screening. It also describes early budbreak, flowering and ripening, together with large berries. Napa River trial plantings supplied fruit for commercial-scale winemaking tests.

These observations answer different questions. Screening tests resistance to a particular pathogen; vineyard and cellar trials examine growing behaviour and wine potential. Neither the hybrid label nor that resistance result establishes immunity to mildew or tolerance of severe winters. Early budbreak also needs to be considered against local spring-frost risk.

From California breeding to Texas wine

Red Rock Vineyards provides a documented commercial example in Texas. Its 2023 Camminare Noir is identified as an estate wine from Bastrop, with a producer description emphasizing dark fruit, sour cherry and relatively gentle tannin. This is evidence of a specific wine, not a settled flavour template for the variety across regions.2. Red Rock Vineyards, “2023 Camminare Noir,” estate and location information. Its tasting description applies to that bottling.

The geographic distinction matters. California supplied the breeding programme and early trials; Texas supplies one example of adoption in a different setting. As more vineyards accumulate experience, site choice, crop balance and maceration will help explain variation between bottles.

Blanc du Bois offers an instructive comparison: it addresses the same bacterial constraint through a different breeding history and makes white wine. Together they show why disease resistance can expand a region's choices without determining a single wine style.
