Hop Qualities

Ultra Rhizome Flavor

A triploid aroma-type cultivar, originated in 1983 from a cross between the colchicine-induced tetraploid Hallertau mf (USDA 21397) and the diploid Saazer-derived male genotype (USDA 21237m). Ultra is the half-sister to Mount Hood, Liberty and Crystal. Its genetic composition is 4/6 Hallertau mf, 1/6 Saazer, and 1/6 unknown. This cultivar was released for commercial production in March, 1995. It has a peppery, spicy aroma similar to Saaz. Substitutes: Crystal, Saaz, Tettnanger. (Reference)

    Everyone who saw my garden wanted to know what that gorgeous plant was! Next year they will be covering a 20′ x 20′ purgola. Thanks again!

  • David R. Waite

    I wanted to tell you how extremely pleased I am with the quality of these hops! I have never purchased whole hops that look and smell this wonderful.
    Thanks for quick turnaround on the order, and for making hops of this quality and value available to fellow homebrewers.

  • Joe Harris

    I called you on a Friday and ordered 8 rhizomes. The following Monday, I received the order in the mail. You must have processed my order immediately for it to arrive that quickly, thanks! Special thanks to you for tremendous service, great products at great prices.

  • Robert

    Just from the feel, and smell, of these hops, I can say that (Greg Noonan’s recommendation) was right on the money… thanks for a great product!

  • John Boston

    As a 13 year home brew veteran, and former president of the Fellowship of Oklahoma Ale Makers, I must say your hops were the freshest and highest quality I have ever seen or smelled. I have been a Northern Brewer fan since visiting the Anchor Brewery in 1987, but I have never come across any Northern Brewer hops that rivaled those Anchor uses... until this batch arrived. The 4 oz of Cascade that came as part of your Value Pack were also a delight to behold.

  • Rick Oftel

    Just wanted to thank you again for the extremely fresh and prompt shipment of my last order.
    Just last evening, I brewed up a German style lager using the N.Z. Hallertauer and Magnum whole hops.
    Looking forward to many future purchases and just wanted to thank you for your attention to detail and also for allowing me the chance to make such great beer!

  • Sherry Leveque

    I received your root stock in record time and excellent condition. I am impressed.

  • Mitch K.

    I have worked at two of the three largest nurseries in America, but I can’t recall anything that has a more vigorous growth rate than these hops.
    I just wanted to say thanks for the fast service and viable rhizomes. You are a great company!
