Tomahawk Hops

Published on

Tomahawk was developed in the 1980s by Charles Zimmerman, who formerly worked for the U.S. Department of Agriculture. The exact lineage of Tomahawk is unknown, but it’s believed to have roots in Brewer’s Gold and several undisclosed American varieties. Often referred to as CTZ, this hop is part of a trio including Columbus and Zeus, with all three being technically the same hop due to a legal dispute between Hopunion and Yakima Chief.

Tomahawk’s aroma and flavor profile is quite intriguing, as it features a punchy hoppiness and an aroma with understated citrus notes. Descriptors for its aroma include black pepper, licorice, curry, and a subtle hint of citrus. When used fresh, Tomahawk can impart a herbal flavor with a lemon citrus back note, making it perfect as a dual-use hop.

With its unique characteristics, Tomahawk works well in American-style ales like American Pale Ales, American IPAs, Stouts, Porters, and Barleywines. Additionally, it can be used in hop-forward Lagers or even Belgian-style ales, providing a distinct twist to traditional flavor profiles.

Tomahawk Hop Oil Breakdown

Hop oils can vary from year to year and farm to farm but based on our research, here are the typical values we have seen reported. This information comes from various hop farms, The Hop Aroma Compendium, and For The Love Of Hops.

Alpha Acid % (AA)
Alpha acids are what is isomerized when boiling to create bitterness in beer.
15% – 17.5%
Beta Acid %
Beta acids are what give hops their more aroma and flavor compounds.
4.5% – 6%
Alpha-Beta Ratio
This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties.
3:1 – 4:1
Co-Humulone as a % of Alpha
Higher numbers are said to impart a harsher bitterness.
28% – 35%
Total Oils (mL/100g)
With more total oils, typically comes a more complex hop profile but these are highly volatile compounds.
2.5mL – 4.5mL
green, resinous
45% – 55%
woody, piney
9% – 14%
6% – 10%
0% – 1%

Tomahawk Hop Substitutions

Replacing one hop for another is seldom straightforward but sometimes you don’t have the right hop or the right quantity of hops for the beer you want to make. For those situations, we have made a comprehensive list of hops to substitute on brew day.

These substitutions aren’t perfect as hop chemistry is pretty complex.

We wanted to make this list of substitutions with varietals that are easy to find when possible. For Tomahawk, we recommend substituting with the following hops:

Beer Styles

For the most part, any hop could have a place in just about any beer style. Based on popular beers, historical usage, and our own preferences, we would recommend using Tomahawk for IPA, New England IPA, Pale Ale, Wheat Beer, Golden Ale. That being said, experiment and see what works best for you.
