Origin and Geneology of the Galaxy Hop

Australian Galaxy hops are Australia’s and Hop Products of Australia’s (HPA) greatest success story. Breeding started in 1994 when an Australian female plant known as J78, which is progeny of the variety Pride of Ringwood, was crossed with a male derived from the high alpha German Perle. Galaxy hops were developed by Hop Products Australia in the mid-1990s, but not released until 2009.

Flavor & Aroma Profile of Galaxy Hops

Galaxy is a dual-purpose hop that can be used in all hop additions throughout the brewing process.

Galaxy hops have one of the highest concentrations of essential oils known in hops, which has contributed to its meteoric rise in popularity. Galaxy is often described as having a strong passion fruit aroma and flavor as well as blasts of clean citrus and peach. At times, you can also experience pineapple and tropical fruit hints. Galaxy hops are all tropical fruit with little to no floral, pine, or spice flavors or aromas.

Galaxy is an extremely versatile hop variety. They can work compliment other hops perfectly, or take center stage as the primary flavor. Their high alpha acid content make them especially suited to late boil and dry hopping. Their distinctive mixture of citrus, passion fruit, peach and hints of grass is sure to stand out and create a beer like no other.

Brewing Values for Galaxy Hops

These are the common ranges that we've seen with Galaxy 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.5-9%

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.1:1 - 3:1

Some popular examples of commercial beers that use 100% Galaxy hops in their recipes are Hill Farmstead Double Galaxy IPA, Toppling Goliath Twisted Galaxy & Masthead Galaxy Vice.

Galaxy Hop Substitutions

If the Galaxy hop is hard to find or if you are simply out of it on brew day, you can try to substitute it with a similar hop. The old way of choosing replacement hops was done by experience and "feel". There is nothing wrong with that way. However, we wanted to build a data-driven tool to find your Galaxy substitutions.

Experienced brewers have chosen the following hop varieties as substitutions of Galaxy:

Is Galaxy available in lupulin powder?

Unfortunately, there is no lupulin powder version of the Galaxy hop. Neither Yakima Chief Hops (Cryo/LupuLN2), Haas (Lupomax) or Hopsteiner have created versions of this hop in lupulin powder form yet. Too bad too - it is pure hop lupulin powder, which leads to huge, concentrated flavor when used in the whirlpool or dry hop additions.

We love statistics. We've analyzed hundreds of IPAs, dug into the Hop Growers of America's annual reports[2] and researched the history behind some of the most popular beer ingredients. Here are a few of the things we've found interesting about the Galaxy hop:

  • Galaxy is the most produced hop in Australia, accounting for over over 55% of the total hop production in the country as of 2019.
