Hop Traceability is a crucial tool for brewers, not only for food safety, but to help deliver quality and consistency as well.
“Grower numbers are an important tool used in the hop selection process, as important as variety and lot numbers...This standard has been a part of the hop industry in the Northwest for decades, and has helped guide brewers, not only for reasons of raw material traceability, but also for reasons of consistency and familiarity with individual farms. Grower numbers are one of a number of data points that we log with every brewer’s cut that we assess and have helped us to recognize the farms and the growing regions that produce the best hops for our beers. As commercial hop growing moves out of the Northwest and across the country, having a standardized system in place that connects the bale to the growers in these new regions is obviously important.”

Obtaining a grower number is a free service to the industry and does not require membership in HGA. Grower Numbers are available to those who:
A separate Variety stencil may also be applied to hop bales or packages. US hop variety abbreviations have been harmonized with other countries through discussions of the International Hop Growers Convention (IHGC). These abbreviations follow a three character format, available HERE. To request the addition of a new variety to this list, please contact firstname.lastname@example.org. The complete international list of Variety Codes may be found HERE.
The US Hop Industry has numerous steps in place to ensure only the highest quality hops make their way to breweries. One of these steps includes a standard protocol for the inspection of hops for seed, leaf and stem content developed by the USDA Federal Grain Inspection Service. All hops produced for commercial sale in Oregon, Washington, and Idaho are required to obtain a Federal-State Seed, Leaf and Stem inspection and certificate prior to sale.
Encompassed in the Hop Inspection Manual is guidance for state departments of agriculture to conduct seed, leaf and stem inspections as a joint Federal-State program. The current manual is being updated to reflect changes in hop harvesting and handling technology, and USDA has issued a Policy Bulletin to notify states of the new revisions while the Hop Inspection Manual is being revised. An updated Hop Inspection Manual will be released in 2019.
In addition to mandatory inspections in Oregon, Washington and Idaho, several additional states are implementing this program on a voluntary basis, in order to provide customers with consistent quality information.
Hops may also be analyzed for Brewing Value to quantify alpha and beta acid compounds, as well as a range of other essential oils and flavor compounds. Laboratories offering these services are included in the Supplier Directory.
