California's Top Crops: Almonds, Grapes, Strawberries, and More

California ranks as the most agriculturally productive state in the United States, generating approximately $59 billion in farm receipts annually (USDA National Agricultural Statistics Service, California Agricultural Statistics Review). The state's diverse commodity portfolio spans field crops, tree nuts, fresh fruits, vegetables, and wine grapes — each governed by distinct production practices, water requirements, and regulatory frameworks. Understanding which crops dominate California's output, how they are produced, and what drives commodity decisions is essential for agricultural professionals, researchers, and policymakers working within the state's farm sector. The California Agriculture Authority serves as a reference point for this sector's regulatory and economic landscape.

Definition and Scope

California's top crops are defined by two primary metrics: gross value of production and harvested acreage. The California Department of Food and Agriculture (CDFA) publishes an annual report ranking commodities by these measures. As of the most recent full reporting period, the leading commodities by value include:

Almonds — consistently the highest-value crop, with approximately 1.4 million bearing acres statewide (NASS California Almond Acreage Report)
Grapes — encompassing wine grapes, table grapes, and raisins across roughly 850,000 total acres
Strawberries — concentrated in Monterey, Santa Cruz, San Diego, and Ventura counties, with approximately 40,000 harvested acres
Dairy products — milk and cream collectively represent one of the largest commodity groups by dollar value
Lettuce — dominant in the Salinas Valley, the region producing roughly 70% of the nation's lettuce supply (CDFA Crop Report Data)
Tomatoes — both processing and fresh-market types, with the Central Valley supplying the majority of U.S. canned tomato products
Pistachios and walnuts — complementing almonds to establish California as the dominant tree nut producing state nationally

The California specialty crops category, as defined under federal law, covers fruits, vegetables, tree nuts, dried fruits, horticulture, and nursery crops — a designation affecting federal program eligibility.

Scope limitations: This page addresses field-level production characteristics and commodity structure within California's state jurisdiction. Federal commodity programs administered by the USDA Farm Service Agency (FSA) and interstate trade regulation fall outside the state-level scope described here. Commodities grown exclusively outside California are not covered.

How It Works

California's agricultural output is organized by production region, water access, and climate zone. The California farming regions and California agricultural climate zones pages detail the geographic differentiation that underpins crop suitability.

Almonds are produced almost exclusively in the San Joaquin and Sacramento valleys. The crop requires cross-pollination, making California's commercial almond industry entirely dependent on managed honeybee colonies — approximately 1.7 million hives are transported into the state each February for bloom, representing the largest annual pollination event in U.S. agriculture. Almonds are harvested mechanically via trunk shakers and require significant irrigation, averaging roughly 3.5 acre-feet of water per acre per season.

Grapes divide into three commercially distinct categories:

Category	Primary Regions	Primary Use
Wine grapes	Napa, Sonoma, Central Coast, Lodi	Wine production
Table grapes	San Joaquin Valley (Fresno, Tulare, Kings)	Fresh consumption, export
Raisin grapes	Fresno County	Dried fruit processing

California wine grapes and viticulture is governed by a separate body of Alcohol and Tobacco Tax and Trade Bureau (TTB) regulations covering American Viticultural Area (AVA) designations, of which California contains over 140 recognized zones.

Strawberries operate on a distinct production model relative to tree crops. The crop is annual, with fields replanted each season using certified virus-tested transplants. Monterey County alone accounts for more than 40% of California's strawberry acreage. The strawberry industry is also among the most labor-intensive in California agriculture, intersecting directly with California agricultural labor and California farm worker protections regulatory frameworks.

Common Scenarios

Agricultural professionals and researchers encounter California's top crops across a range of operational contexts:

Export documentation and compliance: Almonds and pistachios collectively account for a significant share of California's agricultural export volume. The California agricultural exports framework involves CDFA phytosanitary certification, USDA Animal and Plant Health Inspection Service (APHIS) oversight, and destination-country import protocols.
Water rights and irrigation planning: Almond and grape production are among the highest per-acre water users in the state. Disputes over water allocation for these crops intersect with California water rights in agriculture and active drought impact planning.
Pest and disease management: Almonds face pressure from navel orangeworm and hull rot; grapes are vulnerable to Pierce's disease and powdery mildew; strawberries require management of Botrytis cinerea (gray mold). The California pest management regulatory structure administered through CDFA and county agricultural commissioners governs pesticide use on all listed commodities.
Land use conversion: The conversion of irrigated farmland to almond or pistachio orchards — versus row crop rotation — triggers distinct California agricultural land use considerations under the Williamson Act.

Decision Boundaries

Commodity selection in California agriculture is constrained by four primary decision factors:

Water availability and cost — Perennial crops such as almonds and wine grapes lock growers into multi-decade water commitments. Drought years and Sustainable Groundwater Management Act (SGMA) compliance obligations have increased the financial risk of new orchard establishment in overdrafted groundwater basins.
Labor requirements — Strawberries require hand-harvesting, creating dependency on seasonal labor supply. Almonds and processing tomatoes are fully mechanized at harvest, fundamentally changing labor cost structures.
Market channel alignment — Wine grapes destined for premium appellations operate under vineyard designation contracts tied to AVA geography. Table grapes and raisins sell into commodity markets with different price volatility profiles.
Regulatory compliance burden — Organic certification under USDA National Organic Program (NOP) standards, pesticide use reporting to county agricultural commissioners, and food safety compliance under the FDA Food Safety Modernization Act (FSMA) Produce Safety Rule all vary by commodity type and scale of operation.

Growers transitioning between commodity types — for example, converting wine grape vineyards to table grapes, or fallowing row crops to plant almonds — must navigate overlapping California agricultural regulations and potential impacts on subsidy eligibility under California agricultural subsidies and grants programs.

The contrast between annual crops (strawberries, lettuce, processing tomatoes) and perennial crops (almonds, grapes, walnuts) is the foundational decision boundary in California commodity agriculture: annual crops offer flexibility and seasonal reallocation; perennial crops offer long-term yield stability but require 3–5 years of non-bearing investment before production begins.
