Origin and Geneology of the Columbus Hop
Columbus has an unknown origin. It is often referred to as CTZ (Columbus / Tomahawk / Zeus) due to Hopunion and YCH attempting to register the same hop with different names. After an agreement was reached between the two names, both names were registered. They are technically the same hop however. It is genetically distinct from Zeus hops, but has a very similar profile.
The exact lineage of Columbus is unknown, however it is widely assumed that Brewer’s Gold and several undisclosed American varieties played significant parenting roles. It was developed in the 1980s by Charles Zimmerman who had worked for the U.S. Department of Agriculture until 1979 and who subsequently held positions with various private hop-processing and trading companies.
Flavor & Aroma Profile of Columbus Hops
Columbus is a dual-purpose hop that can be used in all hop additions throughout the brewing process.
Specific aroma descriptors of the Columbus hop includes earthiness, black pepper, licorice, spice (curry) and subtle citrus. The floral and citrus notes from the Columbus hop come out in both aroma and flavor, but can be pungent. This strong flavor and aroma make the Columbus hop great for late additions to a boil or dry-hopping.

Brewing Values for Columbus Hops
These are the common ranges that we've seen with Columbus hops over the years. Each year's crop can yield hops that have slightly different qualities, so these number ranges are based on history.
|Alpha Acid % (AA)|
Alpha acids are the main source of bitterness in beer. Longer boil times will result in isomerization of more alpha acids leading to increased bitterness. Learn more »
|Beta Acid %Beta acids are a component of hop resins responsible for contributing volatile aromatic and flavor properties. Beta acids contribute no bitterness.||4.5-6%5.3% avg|
|Alpha-Beta RatioThe ratio of alpha to beta acids dictates the degree to which bitterness fades during aging. 1:1 ratios are common in aroma varieties.||2:1 - 4:13:1 avg|
|Hop Storage Index (HSI)The HSI indicates the percent of alpha and beta acids lost after 6 months of storage at room temperature (68°F or 20°C).||45% (Poor) 0.40-0.50|
|Co-Humulone as % of AlphaLow cohumulone hops may impart a smoother bitterness when added to the boil as opposed to higher ones that add a sharper bitterness to the final beer. Learn more »||28-35%31.5% avg|
|Total Oils (mL/100g)These highly volatile, not very soluble oils are easily boiled off, but add flavor and aroma to the finished beer when added very late in the boil or during fermentation. Learn more »||2.5-4.5 mL3.5mL avg|

Is Columbus available in lupulin powder?
Yes! There is a version of the Columbus hop in lupulin powder form. Columbus lupulin powder is suggested to be used at about half the amount as you'd normally use with pellets. The Cryo/LupuLN2 (Yakima Chief Hops), Lupomax (Haas) and Hopsteiner products are pure concentrated lupulin powder, which add big flavor when used in the whirlpool or dry hop additions.
