2026 Arizona Wine Grape Harvest Report Form

About the Report

The University of Arizona Cooperative Extension is collecting the 2026 Arizona Wine Grape Harvest Report as a statewide initiative to document winegrape production, water use, fruit movement, and pricing. This year's report expands on the work from the 2025 Wine Grape Harvest Report to capture irrigation water use and the reasons behind unharvested acreage and unsold fruit. The 2026 report is supported by a specialty crop block grant focused on the water footprint of Arizona's wine grape industry.

All data are kept secure and confidential. Individual operations are never identified.
Results are reported in aggregate only.

Directions

This report is intended for commercial wine grape growers in Arizona. Please report only grapes grown and harvested from your own vineyard(s) during the 2026 season.

A confirmation of your submission will be sent to this address.

Why we're collecting water use data Based on industry feedback from the 2025 report, we are including a measure of irrigaiton for the 2026 vintage. The purpose of collecting and reporting water use by the Arizona Wine Industry is to highlight the relatively low water use and high agricultural and economic output of the wine industry.

Please only report water applied during 2026

Not enough information to estimate water use
Method: Total Gallons

We will calculate: acre-feet = total gallons ÷ 325,851

—
Method: Pump Flow Rate & Hours

We will calculate: acre-feet = (GPM × pump hours × 60) ÷ 325,851

Gallons per minute — found on pump nameplate or from a flow test

Sum of all pump run time hours during the 2026 season

—
Method: Emitter-Based Estimate

We will calculate: acre-feet = (emitter GPH × number of emitters × total hours) ÷ 325,851
Total emitters = emitters per vine × total vines at this site.

Gallons per hour per emitter (from spec sheet or label)

Emitters per vine × total vines

Total hours all emitters ran during the 2026 season
