Green Bullet Hops

Dual: Aroma and BitteringAlpha 11.0 - 15.0%New Zealand

Green Bullet stands as a historic cornerstone of Southern Hemisphere hop cultivation, originally developed by the New Zealand Plant & Food Research as experimental Brand 65-3-82 and officially released for commercial use in 1972. Bred from an open-pollinated Smoothcone parent to yield high alpha acids, it was specifically engineered to be completely resistant to Black Root Rot disease, an agricultural plague that had decimated New Zealand's hop yards during the 1940s. While it forged its reputation as a bulletproof commercial bittering workhorse to hit high bittering lines in mass-market lagers, craft brewers quickly embraced its dual-purpose capabilities. Though its acreage has been on a decline over the past 10 years due to the explosion of modern tropical varieties, Green Bullet remains a respected, highly versatile staple that effortlessly bridges mid-century processing efficiency with authentic craft performance.

The profile of Green Bullet presents a highly unique, transitional sensory experience that beautifully balances a rugged, old-world structure with a subtle splash of New World fruit. It anchors its aromatic blueprint in a traditional, dominant, and spicy core of resinous pine and freshly cracked black pepper, capturing a classic woody character. However, unlike one-note industrial bittering hops, Green Bullet's substantial oil concentration yields a complex secondary profile of warm dried orchard fruits, dark plums, and heavy floral elements. This dual-natured behavior allows the hop to exhibit a deep, multi-dimensional presence, imparting a clean, crisp bittering punch to lagers while retaining enough aromatic muscle to hold its own against robust, heavily roasted specialty grain bills.

Substitution Tip

If you can't find Green Bullet, the best alternatives are Liberty, Mount Hood, Pacific Gem, or Styrian Golding.
