Hops Production – WinterHops Growers of America Trellis construction after harvest Cover crop establishment between rows Rhizomes cut from dormant hop plants (crowns),potted plants transferred to greenhouse to breakdormancy, allowing propagation through cuttings
Hops Production – SpringHops Growers of America New hop yards planted– Rhizomes in early spring, potted plants later – high quality material Drip irrigation installed Initial fertilizer applications based on soil testing– In-season nutrients applied based on plant tissue analysis Trellis and irrigation systems repaired Primary shoots emerge from hop yard– Pruned to eliminate disease inoculum, training dates set and established Twine tied to overhead trellis, inserted in each hill
Hops Production – SummerHops Growers of America Bines expand with sidearms that bear the crop– Burrs emerge first,then cones (strobiles) develop– Hops bloom from summer solsticethrough JulyUSA HopsUSA Hops IPM, plant protection materials applied Hops harvested from August through October
Hops Production – FallHops Growers of America Hops are harvested, dried, and baled Department of Agriculture inspectorscollect samples to verify crop qualityfor merchants and brewing customers Gigantic Brewing Brewers visit farms and merchants for hop selection Hops go into dormancy after the first killing frost Drip irrigation is removed from the hop yardsJukoFF CC BY-SA 4.0
Hops Production History in the U.S. 1648 – Massachusetts Mid-1800s – New York– Prohibition, downy mildew Early 1900s – Washington,Oregon, California 1933 – End of Prohibition, expansion of hopsacreage WWII – Idaho expands acreage 1990 – California commercial hops production ends Present – Pacific Northwest produces over 97% ofU.S. hopsGorst Valley Hops

Hops Production in the U.S. Generally restricted to a band ranging from 35 to 50degrees north latitude (about 1000 miles wide)– Memphis 35.1495 N– Bristol 36.5951 N Two factors negatively impact hops production asone proceeds south– Lack of sufficient sunlight during the growing season– Lack of adequate chilling over winter months
Lack of adequate chilling during season? Hops reported to need 1-2 months of wintertemperatures below 40 F Dependent of variety and weather Inadequate chilling may not be a problem in TN– Currently regularly crop peaches in Memphis– Peaches have a chilling requirement of 1,000 hours– but may have come close to inadequate chilling inwinter of 2017-2018
Lack of sufficient sunlight during season? Hops need long day lengths to flower andproduce adequate cone yields Lack of sunlight could be significant problem FL and VA looking at supplemental lighting –economically viable?
Viability of Hops Production in SEAgronomically Several years of regional hops research– NC State, Virginia Tech, University of KY Lots of challenges– “Yields tend to be low ”– Daylength, disease, insects– “Where day length is too short, flowering occurswhen node number is met,but before the plants haveput on a lot of growth.”– Relatively high fertility needs– Weeds, insects, diseasesGreat Lakes Hops
Requirements – Producer Level Market Site selection––––Elevation and uniform gentle slope (2-5%) facing NEDeep, well-drained, sandy loam soilpH 6.0-6.5Good air circulation Irrigation Equipment, transport, storage– Sell wet hops immed. after harvest Production, labor costs– H2A Industry Standards––––FSMAGAPQuality InspectionHops Traceability
Research Needs Multi-location field research at four UT RECsrepresenting different regions within TN– Variety evaluation, development– Plant populations and spacings– TrellisingSource: JeanineDavis, NCSU Types of trellises, heights– Disease, insect, and weed management There are pesticides labeled for hops – state labels TN has different pest pressure than other hops– Soil fertility and nutrient monitoring Nutrient sources, other products, application methodSource: selbstfotografiertvon Marti
Many of our clientele who are interested in hops are passionate about the crop and their plans.have “researched” the topic.are optimistic, determined, and “ready to go”.ambitious in scale of production.have high expectations for profitabilitydon’t care about it.have limited to no agricultural experience.lack equipment and may lack consistent labor.underestimate challenges and limitations.may overestimate rewards of their efforts.can be challenging in communications.may be vulnerable.orneed assistance, so we must prepare ourselves.
Summary May be a potential crop for some people in TNLots of unanswered questionsThere are reasons for current hops production areasResearch before production– Develop and disseminate fact-based materials for mostinformed decision – takes time and money Planning, networking, education, moderation At this point, it is high risk

A Brief History of Hops in Beer Hops are a relatively new addition to the brewmaster’s toolkit. Prior to the widespread adoption of hops, beer was bittered and flavored with spice and herb mixtures sometimes called gruit. Any number of herbs and spices went into gruit including henbane, wild rosemary, heather, ginger, spruce, juniper, and
Wisconsin growers associated with Gorst Valley Hops and the Wisconsin Hop Exchange also pose some competition. However, the market in Wisconsin is also still developing and demand exceeds supply. As a result, these growers are focused on providing Wisconsin hops to Wisconsin brewers and ha

Mar 03, 2011 · According to the folks at Gorst Valley Hops, Wisconsin produced 11 million pounds of hops in 1867, 2 million of which were produced in Sauk County. Once again there is a resurgence of hop production in Wisconsin. In d
The width of the in-row weed-free strip is a matter of soil type and grower preference. Generally, the strip’s width should be wider on soils that have low moisture holding capacity. A width of 4 feet is probably adequate, but we have limited experience with hops on Indiana soils. File Size: 666KBPage Count: 17
