  • Process for producing tetrahydroisoalpha acids
    Patent number: 5600012
    Abstract: Tetrahydro-iso-.alpha.-acids ("THIAA") are prepared directly from iso-.alpha.-acids ("IAA") by hydrogenation. Free IAA are first dissolved in ethanol. The solution is then hydrogenated in the presence of a particular type of noble metal catalyst. Hydrogenation is controlled naturally by the reaction between the catalyst and the IAA so that the IAA will be selectively converted to THIAA without unacceptable perhydrogenation into other forms.

  • Hop plant named H87311-3
    Patent number: PP8812
    Abstract: A new variety of hop plant (H87311-3) originating as the result of a controlled cross pollination between an unpatented John I. Haas, Inc. female hop plant No. 832-17 with an unpatented John I. Haas, Inc. male hop plant No. 833-53M, and unique particularly for its cones' unusually high percentage of alpha acids when compared to its female grandparent variety Galena (unpatented) and otherwise as herein described.

  • Hop plant named "H87207-2"
    Patent number: PP8823
    Abstract: A new variety of hop plant (H87207-2) originating as the result of a controlled cross pollination between unpatented Galena female hop plant with unpatented John I. Haas, Inc. (Haas) male hop plant No. 833-53M, and unique particularly for its cones' unusually high percentage of beta acids when compared to its female parent variety Galena (unpatented) and otherwise as herein described.

  • Hop plant named `H900322-4`
    Patent number: PP10147
    Abstract: A new and distinct triploid hop, Humulus lupulus, plant selected from the progeny of USDA `21055` X John I. Haas, Inc. No. `833-53M`, characterized by an unusually high percentage of alpha-acids, coupled with a high yield. This plant also has a high amount of farnesene as a component in the essential oil (8.8% of the total oil is farnesene). None of the USA high alpha-acids varieties has farnesene in the oil. Further, `H900322-4` (hereinafter "H900322-4") has a higher cohumulone content (44.0%) of the alpha-acids than any of the USA high alpha-acids varieties. Harvest maturity is medium-late, with `Nugget` and following `Galena` by about 1 week. Cone size is medium to large yet compact and ovoid, and easily machancially harvested. Cones are non-shattering, and have bracts that are of a darker green color than bracteoles, resulting in a striped appearance.
