Centennial is the bigger, brighter sibling of Cascade β€” so similar in character yet so much more intense that it earned the nickname "super Cascade." It is a cornerstone of the classic American IPA and inseparable from one of the most famous IPAs ever brewed.

#Character

Centennial offers a clean, assertive citrus β€” grapefruit and lemon β€” with a pronounced floral lift and gentle pine. It is more intense and slightly higher in alpha acid than Cascade, making it both a capable bittering hop and a vivid aroma hop. The profile is bright and "classically American" without the tropical sweetness of newer varieties.

β—†The Pliny connection

Russian River's Pliny the Elder, the beer that crystallized the Double IPA as a style, leans heavily on Centennial alongside Simcoe and Amarillo. For a generation of brewers, that trio was the West Coast IPA aroma.

#Use in IPA

A true dual-purpose hop, Centennial bitters cleanly and finishes brilliantly in late and dry-hop additions. It is a frequent partner to Cascade and Simcoe, adding focus and citrus punch to a hop bill.

✦A bridge hop

Centennial sits between the gentle classics and the modern fruit bombs. It is an ideal "anchor" in a blended hop bill β€” providing recognizable citrus structure while letting flashier varieties like Citra or Mosaic supply tropical top notes.

Widely grown and reasonably available, Centennial remains a dependable, lower-cost choice relative to proprietary hops β€” see Hop Contracts and the Hop Supply Chain.
