Genus and species: Humulus lupulus L.
Variety denomination: ‘IH13022’.
BACKGROUNDThe present disclosure comprises a new and distinct cultivar of Humulus lupulus L., and hereinafter referred to by the cultivar name ‘IH13022’.
The new hop plant resulted from open-pollinated seed collected from a ‘Sorachi Ace’ (unpatented) female plant in 2013. ‘Sorachi Ace’ was developed and released by Sapporo Breweries in Japan during the mid-1980s, and this cultivar has had very limited commercial success in the United States. The paternal parent is unknown. The resulting hop plant was selected when growing in a greenhouse in Corvallis, Oregon in February 2014.
SUMMARYDuring September 2013, open-pollinated seed was collected from the female hop cultivar ‘Sorachi Ace’ near Corvallis, Oregon (
Based upon agronomic performance and the initial sensory assessment, ‘IH13022’ was propagated via rhizomes obtained from the individual motherplant in February 2018 with additional propagation from stem cuttings in a greenhouse in Corvallis, Oregon. Under the direction and control of the inventor, plants were established in 1-gallon pots and transplanted into replicated field nurseries in Oregon's Willamette Valley during the summer of 2018. These fields were managed using standard hop production techniques. Due to aggressive disease and pest control measures, only yield, chemistry, and sensory data were collected from these plots during the 2019, 2020, and 2021 growing seasons. Beginning in October 2019, ‘IH13022’ entered internal sensory evaluations utilizing dry rub and dry hop analyses.
The ‘IH13022’ hop variety is distinguished from other hop varieties due to the following unique combination of agronomic and chemical characteristics. When grown in Oregon's Willamette Valley, ‘IH13022’:
-
- 1. Matures later than ‘OR91331’ (U.S. Plant Pat. No. 31,042) and ‘Sorachi Ace’
- 2. Is tolerant of downy mildew similar to ‘Sorachi Ace’ whereas ‘OR91331’ is resistant
- 3. Yields less than ‘OR91331’, but similar to ‘Sorachi Ace’
- 4. Typically contains lower amounts of essential oil than ‘OR91331’ and ‘Sorachi Ace’
- 5. Contains a lower alpha acid content than ‘OR91331’, but similar to ‘Sorachi Ace’
- 6. Contains less beta acids than either ‘OR91331’ or ‘Sorachi Ace’
- 7. Contains differing amounts of 20 essential oil components implicated in beer flavor and aroma as compared to ‘OR91331’ and ‘Sorachi Ace’
Asexual reproduction of the new hop cultivar ‘IH13022’ was first performed in Corvallis, Oregon by rhizomes in 2018. Subsequent propagations have been via rhizomes and stem cuttings, and this cultivar has remained genetically stable.
The following detailed description of the ‘IH13022’ cultivar is based on observations of various 2-4-year-old plants, 1st propagation generation, growing on a hop farm in Oregon's Willamette Valley between 2019 and 2021. The original motherplant has been observed growing in a cultivated area near Corvallis, Oregon. The new cultivar has not been evaluated under all possible environmental conditions but was developed for Oregon's Willamette Valley (USDA hardiness zone 8b near 45 degrees North latitude). Certain characteristics of this cultivar such as growth, color, and cone chemical composition may vary with different grower practices and changing environmental conditions (e.g., light, temperature, moisture, nutrient availability, or other factors). The color descriptions are all based on The Royal Horticultural Society (R.H.S.) Colour Chart, 6th edition, 2015.

Tables 1-6 below provide comparisons between various traits of the cultivar ‘IH13022’, its female parent ‘Sorachi Ace’, and the commercially available aroma cultivar ‘OR91331’ (U.S. Plant Pat. No. 31,042). The aroma hop cultivar ‘OR91331’ was bred for the same target environment as ‘IH13022’, and represents a widely grown aroma hop cultivar in the target environment. ‘Sorachi Ace’ was developed in Japan and has very limited acreage and commercial acceptance in the United States. The cultivar ‘OR91331’ is ideal for aromatic, hop-forward beer styles such as an IPA (India Pale Ale).
As shown in Table 1, ‘IH13022’ typically yields less than ‘OR91331’, but similar to ‘Sorachi Ace’ when grown in Oregon's Willamette Valley, and the observed yield is acceptable for this region.
The ‘IH13022’ cultivar has less alpha acids concentration than ‘OR91331’ but is similar to ‘Sorachi Ace’, and contains less beta acids than either control cultivar (Table 2). The bittering acids provide bitterness to beer during the brewing process. The cultivar ‘IH13022’ also contains higher amounts of cohumulone than ‘OR91331’, and higher colupulone than the other two cultivars. Cohumulone is the major component of the alpha acids while colupulone is the major component of the beta acids. Total essential oil content is lower than either ‘Sorachi Ace’ or ‘OR91331’.
Table 3 shows the concentrations of 22 essential oil components implicated in beer flavor and aroma of the indicated cultivars when grown in Oregon's Willamette Valley.
Tables 4-7 summarize the principal morphological characteristics of ‘IH13022’ when grown in Oregon's Willamette Valley, as compared to female parent ‘Sorachi Ace’ and the industry-standard aroma hop cultivar ‘OR91331’, which was selected for the same growing region.
Lower Canopy Cone Measurements
Cones found in the lower canopy of ‘IH13022’ (Table 4):
-
- 1. have a greater number of bracts and bracteoles per cone than ‘OR91331’ and ‘Sorachi Ace’
- 2. have wider cone bracts and bracteoles than ‘OR91331’ and ‘Sorachi Ace’
- 3. have longer bracts than ‘IH91331’ and bracteoles that are longer than ‘IH91331’ but shorter than ‘Sorachi Ace’
- 4. are longer and have a longer rachis (central strig) than ‘IH91331’ and ‘Sorachi Ace’
Middle Canopy Cone Measurements
Cones found in the middle canopy of ‘IH13022’ (Table 5):
-
- 1. have a greater number of bracts and bracteoles per cone than ‘OR91331’ and ‘Sorachi Ace’
- 2. have wider cone bracts and bracteoles than ‘OR91331’ and ‘Sorachi Ace’
- 3. have a longer bract than ‘OR91331’ and longer bracteoles than ‘IH91331’ and ‘Sorachi Ace’
- 4. are longer than ‘OR91331’ and ‘Sorachi Ace’
- 5. have longer cone petioles than ‘OR91331’
Morphological Characteristics
Compared to ‘IH91331’ when grown in Oregon's Willamette Valley, ‘IH13022’ (Table 6):
-
- 1. has a longer main bine internode length
- 2. has a longer sidearm 1st internode length
- 3. has a wider sidearm 1st internode diameter
- 4. has longer leaves
- 5. has a longer cone petiole
Table 7 lists additional plant characteristics for ‘IH 13022’.
Internal sensory evaluations of hop cones from ‘IH13022’ took place from October 2019 through November 2020. These evaluations include “dry rub” analysis via human sensory for aromatic character, as well as “dry hop” analysis again for human analysis of how the hop character expresses in beer. The “dry rub” involves rubbing the dried hop cones aggressively between a person's hands to rupture the lupulin glands and volatize the oils, at which point experienced personnel evaluate and record the aromatics. “Dry hop” analysis involves adding the dried hop cone material into a neutral base beer and allowing time for the hop oils to transfer into the beer so that hop flavor and aroma can be evaluated in the finished product. The primary sensory observations collected from test brews can be summarized as “bright, fresh peach-lemonade, candied orange peel, mango, boysenberry and guava.”
Another unique characteristic of the hop cones from ‘IH13022’ is that they are void of the typical resinous character (aroma/flavor reminiscent of coniferous tree sap/pitch) that normally comes along with such hops of above average intensity.
