Cascade and Centennial are the two C hops that defined American craft brewing, Cascade launched Sierra Nevada Pale Ale in 1980, Centennial powered Bell’s Two Hearted Ale and countless IPAs through the 1990s and 2000s. I’ve used both individually and blended in hundreds of batches, and the relationship between them is one of the most useful things to understand in American hop brewing: they’re complementary rather than competing, and knowing when to use each one changes the quality of your IPAs.
Cascade vs. Centennial: key specifications compared
Cascade: Released 1972 by USDA, first major American craft hop variety. Alpha acids: 4.5–8.9% (variable, typically 5.5–7%). Beta acids: 4.5–7%. Cohumulone: 33–40% (moderate-high, contributes some harshness at high rates). Total oil: 0.7–1.4 mL/100g. Primary components: myrcene (45–60%), geraniol, linalool. Primary flavor/aroma: grapefruit, citrus, floral, the defining “American craft hop” character. Fresh Cascade has clean grapefruit citrus; aged or poorly stored Cascade develops catty or onion notes from myrcene oxidation. Centennial: Released 1990 by USDA (cross of several varieties including Brewer’s Gold). Alpha acids: 9.5–11.5% (significantly higher than Cascade). Beta acids: 3.5–4.5%. Cohumulone: 28–30% (lower than Cascade, cleaner bittering). Total oil: 1.5–2.3 mL/100g (higher than Cascade). Primary components: myrcene (45–55%), farnesene, linalool. Primary flavor/aroma: citrus-floral with more intensity than Cascade, often described as “Cascade on steroids”, grapefruit, orange, floral, slightly more resinous than Cascade. Centennial’s lower cohumulone means the higher alpha acids produce cleaner bitterness than Cascade.
When to use Cascade vs. Centennial
Use Cascade when: brewing session pale ales, American wheat beers, or any recipe where moderate citrus-floral hop character at restrained bitterness is the goal. Cascade’s lower alpha acid content makes it ideal for late additions and dry hopping in lower-IBU beers where you want hop aroma without the bitterness intensity. Cascade at 0.5–1 oz for aroma additions in a 5-gallon batch produces the clean grapefruit character that made American pale ale famous. Cascade is also the correct choice for beers where the hop character should be approachable rather than aggressive, 150 Lashes, Sierra Nevada Pale Ale, and most session craft pale ales use Cascade specifically for this reason. Use Centennial when: you need clean, intense citrus-floral bitterness for IPA-level hopping. Centennial’s higher alpha acids and lower cohumulone make it one of the cleanest high-alpha American hops, it produces 55–65 IBU in a standard IPA without the harsh, astringent bitterness that higher-cohumulone hops can create. Bell’s Two Hearted, one of the all-time great American IPAs, is made with Centennial alone, demonstrating that Centennial can carry an IPA without blending. The classic blend: Cascade at late/aroma additions + Centennial for bittering and flavor is the backbone of American IPA since the 1990s. Centennial’s clean bitterness provides the IBU platform; Cascade’s grapefruit-floral character fills in the aroma. Goose Island IPA, many homebrew competition-winning IPAs, and the Cascade-Centennial combination in this site’s clone recipes all use this pairing.
Common Questions
Can you substitute Cascade for Centennial at the same weight in a recipe?
Yes for aroma additions, no for bittering without adjustment. For late hop additions and dry hopping, Cascade and Centennial produce similar citrus-floral results and are roughly interchangeable at the same weight, Centennial will be slightly more intense and more orange/floral where Cascade is more grapefruit-citrus, but the character direction is similar. For bittering additions, the alpha acid difference matters: Centennial at ~10.5% alpha will produce roughly 1.5–2× the IBUs of Cascade at ~6% alpha at the same weight. To substitute Cascade for Centennial at bittering: multiply the Centennial weight by 1.75 to get the equivalent Cascade weight (e.g., 0.75 oz Centennial ≈ 1.3 oz Cascade at 60 minutes). Most recipe software handles this automatically via IBU calculation, just plug in the substitute hop with its actual alpha acid percentage and adjust to hit your target IBUs. The bitterness quality will be slightly different: Centennial’s lower cohumulone produces cleaner bitterness than Cascade at the same IBU level. For hop-forward IPAs where bitterness quality matters, the cohumulone difference is noticeable; for session beers at 20–30 IBU, it’s largely irrelevant.
