Bor Hops
AromaAlpha 3.0 - 5.0%Slovenia
Released in 1994 by the Hop Research Institute in Žatec, Bor is a refined Czech variety that represents a brilliant chapter in traditional Bohemian hop breeding. Developed as a deliberate cross between a Northern Brewer seedling and open-pollinated Saaz components, it was engineered to combine reliable dual-purpose versatility with the pristine, delicate essence of classic noble hops. The name itself translates to "pine" in Czech, paying homage to the sweeping pinewood forests native to the country's historic hop-growing regions. Agronomically, the plant is a resilient, medium-early maturing vine that delivers a highly consistent canopy setup and fantastic natural resistance to downy mildew, making it a highly respected specialty crop among traditionalists.
The sensory footprint of Bor is a masterclass in old-world continental restraint, offering a soft, sophisticated bouquet that entirely avoids the aggressive, sulfurous, or overly resinous punch of modern high-alpha hybrids. The aromatic profile opens with a gentle, prominent top note of sweet herbal spice, dried chamomile blossoms, and a whisper of fresh-cut hay. This elegant introduction transitions into a crisp, airy mid-palate defined by subtle wildflower blossoms and a light, clean, earthy minerality. Grounding the entire experience is an incredibly smooth baseline of refined woodiness, soft forest floor, and a distinct, signature touch of clean pine. Thanks to its classic oil chemistry and balanced humulene fraction, Bor excels in late-kettle, whirlpool, or traditional lager cellaring additions where it adds a flawless noble fragrance that beautifully elevates clean malt backbones.
If you can't find Bor, the best alternatives are Saaz, Spalt, Sterling, or Tettnanger.
