The E. E. Cummings Crop Testing Laboratory opened in 2011 as the NWCS Quality Testing Laboratory thanks to funding from the Castanea Foundation and the support from generous private donations. We perform quality analysis on commercial cereal grains, hops, and malting barley samples received from farmers and researchers across the region.

In April 2021, we have renamed the lab to E. E. Cummings Crop Testing Laboratory at the University of Vermont in dedication to our former employee and friend, Erica E. Cummings, who helped establish the lab in 2011.

The lab is equipped with near-infrared technology for protein analysis and employs a method to test for deoxynivalenol (DON) also known as vomitoxin. Occurrences of this vomitoxin in wheat at or above 1 ppm are considered unsafe for human consumption by the FDA. Contamination of wheat with DON is directly related to the incidence of Fusarium head blight and strongly associated with relative moisture and timing of rainfall at flowering.

Our lab also houses a sophisticated machine to test the Falling Number of wheat, an internationally standardized method for sprout damage detection. The Falling Number System measures the alpha-amylase enzyme activity in grains and flour to detect sprout damage, optimize flour enzyme activity and guarantee soundness of traded grain. Alpha-amylase activity is crucial for final product quality of bread, pasta, noodles and malt.

When to test for Aflatoxins (PDF)

Aflatoxins are fungal toxins and are produced by several different molds in the Aspergillius family.

Remember the results are only as good as the sample submitted!

If you have samples you would like analyzed, please send 1) payment and 2) a completed submission form — these must accompany all requests sent in. In order to get results that accurately reflect your product, be sure to employ good sampling techniques.

Grains Testing

We test for test weight, moisture, protein, falling number, and DON in grains. We also conduct analyses for corn (% Moisture, % Crude Protein, % Crude Fiber, and % Starch). New for 2020, we are testing for Aflatoxin (ppb).

To expedite analysis of your sample(s), please provide a completed submission form(s) and payment with your sample(s). Also please make sure you provide 1 quart of clean (no stones and dirt) and dry (<14% moisture) whole grain for each sample submitted. Cereal Submission Form (PDF).

Hops Quality Analysis

Hops Quality analysis is available. We can test for Brewing Values (BV’s) which determines Alpha acids, Beta acids and Hops Storage Index (HSI). Please see our What’s Hoppening blog post for tips on submitting hop samples for quality analysis. Hop Analysis Submission form (PDF).


Malting Barley analysis is now available. We can test for test weight, grain moisture, dry matter protein, falling number, germination, plumpness and DON. Please make sure you provide 1 quart of clean (no stones and dirt) and dry (<14% moisture) whole grain for each sample submitted. Malting Barley Submission form (PDF).
