Centennial was bred at the USDA's Oregon program and released in 1990, descended largely from Brewer's Gold with Cascade in its background — a lineage that shows up directly in how it tastes. Brewers have called it "Super Cascade" for decades, and the nickname is fair: it shares Cascade's citrus-floral backbone at close to double the alpha acid, which makes it useful in places Cascade's lower alpha can't reach on its own.
Why "Super Cascade" undersells it
At 8-11.5% alpha acid, Centennial sits comfortably in dual-purpose territory. It's strong enough to serve as a real bittering charge in a hop-forward beer without needing an oversized weight, and its aroma character holds up well enough in late-boil and dry-hop additions that many recipes use it for both jobs in the same batch — a 60-minute Centennial addition for bitterness, then a second Centennial charge at flameout or dry hop, rather than switching varieties mid-recipe.
Rounder than Cascade, sharper than Amarillo
Centennial's aroma reads as citrus and floral with a slightly sweeter, less sharply grapefruit-forward edge than Cascade — some brewers describe it as rounder or more "floral-lemon" where Cascade leans harder into pith and grapefruit. It's a large part of the hop character in Bell's Two Hearted Ale, one of the most widely benchmarked American IPAs, which uses Centennial as its sole hop variety across the entire boil.
Two Hearted Ale and single-hop use
Because it works as both bittering and aroma hop, Centennial appears across American pale ale, American IPA, and double IPA recipes, often as the backbone variety with a more distinctive proprietary hop (Citra, Simcoe, Mosaic) layered in for a specific fruit note. Its clean bitterness and moderate cohumulone make it a forgiving bittering choice that doesn't add the harsher edge some higher-cohumulone high-alpha hops can.
When Centennial isn't on the shelf
Cascade is the natural substitute when Centennial isn't available, though a straight swap needs a heavier hop weight to hit the same bitterness given Cascade's lower alpha range — run both through the IBU calculator before committing to a 1:1 substitution by weight. Chinook is the second common substitute, sharing Centennial's dual-purpose profile at similarly high alpha acid, though Chinook reads noticeably more piney and resinous where Centennial stays in citrus-floral territory.
Cohumulone and bitterness quality
Centennial's cohumulone content — the share of its alpha acid made up of the harshest-tasting bittering compound — sits in the moderate range, noticeably lower than high-cohumulone hops like Warrior or Apollo. In practice this means a bittering charge sized for a given IBU target from Centennial tends to read smoother than the same numeric IBU from a high-cohumulone variety, which is part of why it's a common default bittering choice even in recipes whose late hops are something else entirely, and why some all-Centennial IPAs read as more balanced and drinkable than their raw IBU number alone would suggest to someone comparing it against a harsher, higher-cohumulone hop bill on paper.
A stable, workhorse variety
Unlike Cascade, whose alpha acid swings widely by crop year, Centennial's range is comparatively tighter and more predictable, which is part of why it's remained a reliable recipe backbone for over three decades rather than falling out of favor as newer proprietary hops arrived. It's public domain and widely grown across Washington's Yakima Valley, so availability and price are rarely an issue the way they can be with single-farm varieties.
