Different cultivars of hops were bred to give brewers varied choices when making different types of beer. The US Centennial hop was bred in 1974 by the Washington State University. However, it was only during 1990 that it was first released to the public. It was a diploid cross of the USDA male and Brewer's Gold.
The US Centennial hop pellets come from the aromatic type cultivar. It provides a medium intensity floral and citrus note. It is one of the most popular types of hop varieties used in craft brewing. It is referred to as the super-Cascade because of its good content of alpha acids. It contains between 7% and 12% of alpha acids as well as 3.5% and 5.5% beta acid. It also contains 1 to 3 ml/100 g of total oil and 23% to 27% co-humulone. This is the reason why this particular hop pellets are not only used for its aroma but also for intense bittering of the final brew. This hop pellets produce a highly intense finished product.
It is suitable for making all types of US-style ales, wheat beers, barley wines, pale ales and IPA. If you cannot find any near you, you can substitute it with Columbus, Chinook or Cascade but the flavours of these three do not match the Centennial hops that much.
Once opened, store it in a cool, dark and dry place to prevent the oils and acids from disintegrating. Use it within 6 months after opening to keep the quality of the finished product.
