All about the hop

The subject of many a pun, hops are the plant parts used in brewing beer. Here’s what you should know about them.

Have you ever seen a hop? They’re odd looking things, almost alien in shape, strung up in a farmer’s field like rows of tiny green grenades – and with flavour just as powerful. Hops are the weapon of choice for brewers all around the world. Quite simply, without them, beer would not be beer as we know and love it.

Botanically, hops are the cone-shaped flowers – or strobilus – of the hop plant Humulus lupulus. This makes hops a part of the Cannabaceae or hemp family of plants, which means that hops and hemp (cannabis) are pretty much cousins – though unlike cannabis, hops contain none of the psychoactive elements. Instead, hops are used at various stages of brewing to impart their alpha acids and oils, which give beer its characteristic flavour.

Hops take centre stage in beers such as IPAs, providing them with their distinctive pine oil, often citrus and sometimes grassy aromas and flavours, as well as bitterness and acidity. However, in dark beers, like stouts, hops are less noticeable, aromatically or flavour wise. Rather, hops give darker beers their structure and backbone, providing them with a greater sense of depth and complexity.

Of course, it all depends on what hops are used and when they are added to the brewing process. In a nutshell, hops are added earlier for bittering, half way for flavour and later for aroma, because fewer aromatic oils are lost to evaporation.

There are around 80 commercial hop varieties, and each has a different aroma, flavour and bitterness expression. Brewers use specific varieties to craft and create a specific beer style, like lagers, ales and stouts. Here are a few you’re likely to hear about most often.


Galaxy is Australia’s superstar hop variety. Born in Tasmania, it’s one of the most versatile Australian-bred hops ever used to brew beer. Brewers love galaxy because of the distinctive passionfruit and peach aromas and clean citrus, pineapple and other tropical fruit flavours it brings to beer. Galaxy is most often used in pale ales and IPAs.


The hop variety that launched a thousand craft beers, cascade is considered the classic American hop. Hailing from Oregon, the home state of American craft beer, cascade hops feature in almost every West Coast IPA and American pale ale ever made. Floral, spicy, zesty, fresh and citrus – sometimes grapefruit – notes are what define cascade.


This particular hop cultivar was discovered growing wild and free in Washington state’s Yakima Valley. Named for its slightly yellow colour – amarillo means ‘yellow’ in Spanish – this once wild variety is known for its fresh orange and grapefruit flavours, with floral and often spicy aromatic overtones. Brewers use Amarillo for its bittering qualities in amber ales and American IPAs.

VIC secret

Another home-grown hero, Vic secret was developed for its high alpha acid and oil composition. Brewers love to use Vic secret in pale ales and IPAs to give them that bright, tropical fruit, pine and herbal sensation. This very Aussie hop can also give a lovely earthiness and structure to dark beers such as stouts and porters.


The hottest hop in the brewing world right now, mosaic is often the star of the show, flying solo in many single-hop variety beers – usually IPAs and pale ale styles. This is thanks to its clean bittering characteristics and unique aromatics, which range from berries, tropical stone fruits and yellow florals to freshly cut grass, crushed herbs, pine and spice.
