Named after the Washington state festival, Centennial is an aroma-type cultivar developed from the USDA hop breeding program at Washington State University in 1974 and released in 1990. Centennial is a well blended aroma hop and is sometimes referred to as Super Cascade Classic floral and citrus. Excellent dry hop. The BBC Pure Hop Pellet™ is produced using a finer, more uniform grind than standard Type 90 pellets. A sub-zero process – milling and sieving takes place at approx. -35°C (-31 °F) – to prevent hop resins and essential oils from oxidation. The resulting pellets offer a more intense aroma and flavour.
