Hop production was common throughout the Northeast in the 1800s. However, today most hop production occurs in the Pacific Northwest. Renewed interest and demand for local hops is breathing new life into an otherwise “historical” crop. To increase hops production in the Northeast, the UVM Extension Northwest Crops and Soils Team conducts a hops outreach and applied research program. See below for our research results–on hop varieties, pest management and more–as well as a number of resources on hop production in our region. Check back here frequently for more information and updates, and subscribe to our hops blog!
New! Recruiting NE Hop Growers for Pest and Nutrient Management Project
Our team is currently recruiting for a 3-year NE-SARE project looking advance pest and nutrient management strategies for Northeast hop production. As a participant, you:
- Complete an introductory survey that allows us to collect basic information about your hop yard, understanding of hop yard management and project learning goals;
- Participate in our bi-weekly goScout program to help us all learn more about pest pressure and management options throughout the region during the season; and
- Learn and share pest & nutrient management information through our Hops Power Hour webinars, offered monthly from April 24 to September 25, 2017.
If you are interested in participating, please click here to complete the introductory survey, but act fast because space in this project is limited and offered on a first-come, first-served basis.

Hops Quality Analysis
We want to thank everyone for supporting the UVM Hop Quality Testing Laboratory!
At this time, we have one test available for Brewing Values (BV’s) which determines Alpha acids, Beta acids and Hop Storage Index (HSI). Click here for the Hops Analysis Submission Form to submit a sample. Please make sure all samples sent are dried properly and are not more than 8-10% moisture as we will not be able to conduct the testing.
