Paso Robles
Location: California, United States
Legal name: Paso Robles American Viticultural Area
Regulatory body: TTB
Official designation: 27 CFR §9.84
Paso Robles is modeled here as the appellation/legal-origin layer for the existing EncyclopediaOfWine region row. It identifies the protected label name associated with California, while the original region row remains available as legacy geographic context until downstream links are fully migrated. The AVA is broad, warm, and internally diverse, with many later nested district AVAs. Commonly associated grapes include Cabernet Sauvignon, Zinfandel, Syrah, Grenache, Mourvèdre, Petite Sirah, Chardonnay. AVA status in the United States is origin-based rather than grape-prescriptive: it protects a delimited place-name and does not require one authorized grape list or a European-style production recipe.
Permitted Grapes
No AVA-specific grape restrictions. Commonly associated grapes: Cabernet Sauvignon, Zinfandel, Syrah, Grenache, Mourvèdre, Petite Sirah, Chardonnay.
Notable Rules
AVA label use is origin-based: under 27 CFR §4.25(e)(3), at least 85 percent of the wine must be derived from grapes grown within the viticultural area, and American wine must be fully finished within the State, or one of the States, in which the AVA is located. The AVA does not impose a grape-variety list or European-style production code.
Recent Vintages
Recent California vintages are best read through climate volatility rather than a single statewide vintage call. Drought, heat spikes, and wildfire-smoke risk were recurring issues through the late 2010s and early 2020s, while 2023 brought broader relief in many regions through winter rain and a slower ripening season. For this appellation, public vintage information is better at the state or macro-region level than at the appellation level, so site and producer decisions remain important.
A general read of growing-season and harvest character — not a rating.
