What are Southern Cross hops and their origin
Southern Cross hops were introduced in 1994, hailing from New Zealand. HortResearch, a renowned breeding institution, created this triploid variety. It's designed for both bittering and aroma applications. The triploid characteristic ensures the plants are seedless and sterile, impacting their propagation and breeding.
The Southern Cross hop's lineage is a blend of genetic sources. It combines a New Zealand research line from the 1950s, a California hop, and the English Fuggle. This combination results in a hop with a clean bitterness and citrus and pine aromas. These qualities are highly sought after by brewers.
HortResearch aimed to create a versatile hop with Southern Cross. They measured its oil and alpha-acid levels to meet brewing requirements. This effort has yielded a hop that provides robust bitterness while also offering aromatic complexity when used in later stages of brewing.
Flavor and aroma profile of Southern Cross hops
Southern Cross hops introduce a vibrant, citrus-centric profile that shines in both aroma and taste. The flavor profile is dominated by lemon and lime, with a zesty quality. This makes them ideal for late boil additions and dry hopping.
These hops also exhibit a piney undertone. The taste reveals a soft pine resin and woody spice beneath the citrus. The bitterness is perceived as gentle, allowing the aroma compounds to take center stage.
Myrcene and farnesene contribute to floral and fruity esters, enhancing the Southern Cross aroma. This blend includes tropical fruit notes like guava and passion fruit. The outcome is a layered, juicy sensation.
Caryophyllene and humulene add spice and balsamic notes. Brewers can anticipate subtle woody spice and resinous depth. These elements balance the citrus and tropical fruit hops without overpowering them.
Choose Southern Cross hops for a lively, clean citrus flavor with a hint of pine and tropical complexity. The aroma is fresh, zesty, and slightly floral. The palate finishes softly and rounded.
Brewing values and chemical analysis
Southern Cross alpha acids usually range from 11–14%, with many samples around 12.5%. Beta acids are typically 5–7%, leading to an alpha:beta ratio of 2:1 to 3:1. This ratio ensures consistent bitterness in both lagers and ales.
The co-humulone in Southern Cross is about 25–28% of the alpha fraction. This level contributes to a smoother bitterness perception compared to hops with higher co-humulone percentages.
Southern Cross total oils range from 1.2–2.0 mL/100g, averaging 1.6 mL. The oil profile is dominated by myrcene, often the major terpene. It is accompanied by humulene, caryophyllene, and farnesene in smaller amounts.
- Myrcene: resinous, citrus, and fruity; found 31–59% in samples.
- Humulene: woody, spicy, noble; typically 13–17%.
- Caryophyllene: peppery, herbal; around 4–6.5%.
- Farnesene and minor terpenes: fresh, floral, and green.
Hop chemical analysis reveals batch-to-batch consistency in Southern Cross. This consistency aids commercial brewers in maintaining flavor targets. The consistent total oils and terpene ratios minimize the need for recipe adjustments between harvests.
Some lab tests report alpha acid spikes to 12–14.5% and beta acids near 6–6.4%. These tests also show occasional myrcene proportion variations. Such variations can alter the perceived citrus or floral traits.
For process control, hop chemical analysis data is crucial. It guides adjustments in kettle additions, whirlpool timing, and dry-hop rates. Monitoring Southern Cross alpha acids, total oils, and co-humulone across lots ensures stable bitterness and aroma.
How to use Southern Cross hops in the brew kettle
When using Southern Cross hops, start with a measured early charge for base bitterness. Then, add smaller late doses to enhance citrus and spice notes. This approach ensures flavors are layered, preventing any one from overpowering the others.
Alpha acids in Southern Cross can reach 12–14.5%, which means you can expect a significant bitterness. Yet, the perceived bitterness is softer than the numbers indicate. If you prefer a firmer bitterness, add the first dose at 60 minutes. For a gentler bitterness, trim the boil time while preserving hop character.
Save a portion of hops for the last 10–5 minutes to protect volatile oils. These late additions bring out lemon zest, pine needle top notes, and a clean spicy edge. This method adds a fragrant lift that complements pale malts and modern yeast strains.
For balanced beers, stagger your additions. Start with a base bittering dose, then add a mid-boil flavor dose, and finish with a late aroma splash. Use small whirlpool rests at 170–180°F to extract oils without harshness. This approach makes Southern Cross boil additions both efficient and expressive.
- 60 min: primary bittering IBU, moderate dose
- 20–15 min: flavor development, moderate to low dose
- 10–0 min: aroma focus, small dose for citrus and spice
- Whirlpool: short rest to enhance aromatic lift
Adjust the hop schedule Southern Cross to suit your beer style and malt bill. In hop-forward ales, increase late additions. For balanced lagers, emphasize earlier hops but keep a late touch for clarity in Southern Cross bitterness and aromatics.
Dry hopping and fermentation additions
Southern Cross is perfect for late boil and fermentation additions due to its high essential oils and low co-humulone. It's best to use whole cone or pellet forms, as lupulin powder is not available for this variety.
For beers that focus on aroma, add Southern Cross to the whirlpool at low temperatures. This captures the delicate citrus and floral esters. A short contact time of 10–20 minutes is often enough to extract lemon zest and pine without pulling vegetal notes.
Dry hopping can enhance spicy and resinous elements. Add Southern Cross dry hop charges during active fermentation or after primary fermentation for a clean citrus lift.
- Early whirlpool: gentle citrus and mild bitterness.
- Late additions Southern Cross at flameout: brighter top notes and fuller mid-palate.
- Short dry hop contact: peak floral and lemon character; avoid excessive time to reduce grassy tones.
Adjust the contact time based on the beer style. Hazy IPAs can handle longer Southern Cross dry hop contact for layered aroma. Lagers and pilsners, on the other hand, benefit from brief Southern Cross whirlpool additions to keep the profile crisp.
Monitor oil pickup and watch for vegetal extraction when using late additions Southern Cross. Start with conservative grams per liter and scale up in future brews once the balance is confirmed.
