Centennial is a mixture that’s 3/4 Brewers Gold, with the remaining composition being made up of Fuggle, East Kent, Golding, and Bavarian. Centennial is named after the Washington State Centennial Celebration, which happened one year before the release of the hop.

Brewing Values of Centennial Hops
Here are the brewing values for Centennial hops. Keep in mind that every year produces different quantities and qualities of Centennial, so these numbers are based on what is usually produced.
- Alpha Acid – 9-12%
Alpha acids are the primary source of bitterness for beer, and the longer you boil Centennial hops, the more bitter it will be.
- Beta Acid – 3.5-5%
Beta acid might have acid in the name, but it doesn’t contribute to a beer’s bitterness, unlike Alpha. Betas’ purpose is to contribute flavor and aroma profile to a beer.
- Alpha-Beta Ratio – 1:1 – 3:1
The ratio you use for adding Alpha and beta acids will determine how bitter your brew is.
- Co-humulone as % of Alpha – 25-30%
The lower the cohumulone % is, the less bitter your beer will be. Higher levels will result in a more bitter taste.
- Total Oils 1.5-2.5 mL
Oils will also add flavor and aroma to the final product. Here are the different oils used with Centennial hops.
- Myrcene – 45-60%
- Humulene – 10-19%
- Caryophyllene – 5-8%
- Farnesene – 0-1%

How to Grow Your Own Centennial Hops
Have we got you curious and thirsty enough to try to grow your own Centennial hops yet? If so, here is some crucial information that you’ll need.
Centennial needs plenty of water like all hops, especially in the first two years of growth. Water Centennial regularly so that the soil remains moist but not flooded. You should be able to stick your finger two inches into the ground at all times and feel moisture.
Centennial requires 6 to 8 hours of sunlight per day. Full sun is ideal unless you live in warmer climates with high temperatures. Where the temperature is consistently in the 80s and 90s, your plant will need a mixture of sun and shade.
Sandy, well-drained loam soil with a pH level between 6.0 and 7.0 is best for growing Centennial hops. You’ll want to plant your rhizome at least four inches deep in the ground and allow enough space for your plant’s roots to spread. Planting each Centennial hop plant 3 to 5 feet apart should be sufficient.
Hops plants are hardy and can thrive in hardiness zones 3 through 8. It’s best to plant Centennial hops between the months of February and April because they can withstand cold temperatures for the most part. However, you want to avoid planting them until after the last frost of the year.
Keep your hop plants trimmed to maintain good growth and reduce pests and diseases. Trimming is also key to keeping hop plants growing vertically instead of horizontally. If needed, use a pole or post to help train your plants to grow in a vertical direction. At times, you may need to also introduce a fungicide or herbicide into the hop growth process to keep mildew and pests at bay.
Centennial will grow to a height of 20-25 feet tall, so you’ll want to plant them outdoors. You should also provide a trellace or support system to aid them as they grow tall.
