About the North Carolina Hops Project
Spurred on by the demands of a burgeoning craft brewing industry and a strong public interest in locally grown ingredients, farmers are experimenting with hops (Humulus lupulus) as an alternative income source. Over the past ten years, an increasing community of growers across North Carolina and the entire South Atlantic region have established hop yards and sold their products to local craft breweries and home brewers. The majority of information and figures regarding hops production in the U.S. is developed for the Pacific Northwest hops industry and is not intended for the unique agronomic, economic, and environmental conditions found in Southeast. The objective of this project is to help identify the best performing hop cultivars, evaluate and develop appropriate cultural practices, evaluate promising geographic areas for hops production, breed new varieties, address the key issues related to nutrition, disease, and pest control, build a Southeastern hops community, and provide educational materials and programming. In addition, local market conditions and production costs are being addressed.
The 2010-2012 NC Hops Project
In 2010, with support from the Golden Leaf Foundation, Rob Austin and Scott King in the Soil Science Department (now Crop and Soil Sciences) and Jeanine Davis in the Department of Horticultural Science, collaborated on a hops research project. An experimental hop yard was established at the Lake Wheeler Road Field Laboratory in Raleigh, North Carolina. It included 200 total hops plants on 1/4 of an acre. The hop yard contained 10 different U.S. hops varieties planted randomly throughout the experimental site. The varieties were selected based on their range of alpha acid content (bitterness), yield potential, disease and pest resistance, total U.S. production, and demand by local craft breweries. The site was designed to test which hop varieties are best suited for North Carolina’s unique growing conditions and which varieties offer the greatest potential for commercial production. After two growing seasons, the varieties planted show significant variation in their vigor, height, yield, maturity times, pest and disease resistance, and overall agronomic health. For example, while 7 of the 20 plants of the variety ‘Zeus’ were at the top of the 12 foot trellis and producing cones, the tallest ‘Northern Brewer’ was 6 feet, visually stressed, and without cones. Although variation was expected during the establishment year and additional research is needed, it is clear that variety selection plays a significant role in the economic viability of locally grown hops.
Due to changes in workforce, the hop yard at Lake Wheeler was dismantled after the close of the 2012 growing season. Efforts shifted to the research hop yard in the mountains at the Mountain Horticultural Crops Research and Extension Center in Mills River. Established in 2011, this variety trial initially included most of the same varieties as the original trial at Lake Wheeler. Additionally, collaborations continued with growers across the state. The growers worked with us to help monitor, test, and analyze various agronomic conditions and their significance throughout the growing season. These pioneering growers provided an opportunity to analyze the agronomic requirements and disease and pest pressures of hop yards managed under different strategies, in different stages of establishment, and in a different region within the state. This research hop yard still exists.
