Chinook was released by the USDA breeding program in 1985, a cross of Petham Golding and a USDA high-alpha male, and named after the warm, dry wind that sweeps through the Pacific Northwest each winter. It arrived a few years after Cascade and Centennial had already established American hops as a serious breeding category, and it carved out its own identity by leaning harder into resin and pine than either of its predecessors.
A sharper bitterness than its C-hop peers
Chinook pulls its weight at both ends of the boil: 11-14% alpha acid is strong enough for a full bittering charge, and distinctive enough that many brewers use it late in the boil or as a dry hop specifically for its character rather than switching to something milder. Its bitterness reads sharper than Centennial's at a comparable IBU number, which some recipes lean into deliberately for a more aggressive West Coast profile and others deliberately dial back by pairing it with a lower-cohumulone hop.
Pine, grapefruit, and real pungency
Pine and grapefruit dominate Chinook's aroma, with a spicy, slightly herbal undertone that reads more pungent and resinous than Cascade's brighter citrus or Centennial's rounder floral-citrus blend. Used heavily — a large dry-hop charge, in particular — Chinook can tip into an assertive, almost dank sharpness that some brewers actively want in a hard-hitting West Coast IPA and others find overpowering if it's not balanced against a fruitier variety.
Rarely the only late hop in the kettle
Chinook shows up across American pale ale, West Coast IPA and double IPA, most often as a supporting bittering or mid-boil hop rather than the sole late-addition variety, since its assertive character can dominate a hop bill if it's the only late hop used in any real quantity. It also appears in some American amber and brown ales looking for a resinous, slightly spicy edge rather than a sweeter, more caramel-forward hop character.
Columbus for pungency, Centennial for citrus
Columbus is the closest substitute for Chinook's bittering role, sharing a similarly pungent, resinous character at an even higher alpha range, though Columbus reads more purely earthy-dank and less citrus-forward than Chinook's grapefruit note. Centennial is the second common substitute when the goal is Chinook's citrus side without quite as much pine and resin — a milder, more floral alternative at a comparable alpha range.
Part of the original "C-hop" wave
Chinook arrived alongside Cascade, Centennial and Columbus as part of what brewers later nicknamed the "C-hop" family — American varieties released within roughly a decade of each other that, between them, defined the citrus-and-pine vocabulary of 1990s and 2000s craft IPA before the proprietary Citra-and-Mosaic era shifted the conversation toward tropical fruit. Chinook was the most aggressively resinous of that original group, and recipes built to evoke an "old-school West Coast IPA" still often reach for it specifically for that reason.
A hop that ages differently
Run a planned bittering charge through the IBU calculator with the actual lot's alpha acid before finalizing a recipe. Chinook's oil profile holds up reasonably well in storage compared with more delicate tropical-fruit-forward varieties, but like most high-myrcene American hops it will drift toward cheesy, oxidized notes if stored warm or exposed to air for extended periods — vacuum-sealed and refrigerated or frozen storage matters more for preserving its sharper pine character than it does for a more herbal, lower-oil noble hop that has less volatile aroma to lose in the first place.
