Origin and Geneology of the Topaz Hop

Topaz was bred from an existing Australian high alpha acid variety crossed with pollen from a Wye college male. Topaz was created by the HPA breeding program in 1985 and commercialized in 1997. It did not find popularity until 2011.

Flavor & Aroma Profile of Topaz Hops

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

Topaz hops have light, tropical fruit flavors of lychee, clove-like spice and resinous grassy tones. This is a fantastic hop to use when dry hopping. When used with later additions and in higher gravity brews, specific flavor qualities come out as pleasant, and more pronounced light tropical fruit.

Brewing Values for Topaz Hops

These are the common ranges that we've seen with Topaz 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.4.9-7.9%
6.4% 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 - 4:1

Topaz Hop Substitutions

If the Topaz 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 Topaz substitutions.

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

Is Topaz available in lupulin powder?

Unfortunately, there is no lupulin powder version of the Topaz 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.

Topaz Hop Statistics

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 Topaz hop:

  • Topaz is Australia's sixth most produced hop as of 2019.
  • In 2019, Australia produced 65 metric tonnes of Ella, which was a decrease of 5.8% over 2018.
