Styrian Wolf hops for mango and elderflower in pale ales

A Slovenian hop that leans tropical

Styrian Wolf comes from the Slovenian hop research programme at Žalec, the same institute behind the older Aurora. Most Slovenian hops are known for floral and herbal notes. Wolf adds ripe fruit to that family.

The aroma is described as mango, stone fruit and elderflower, with some citrus peel. It is a dual purpose hop with alpha acids well above the noble hops, so it can bitter a beer as well as scent it. Most homebrewers use it late for the fruit.

Why mango and elderflower in the same hop

Elderflower is a floral note often linked to terpene alcohols such as linalool and geraniol. Mango and stone fruit come from a mix of fruity compounds, with thiols playing a part in some varieties. A hop that carries both gives a pale ale that smells of a fruit market with a garden next door.

You do not have to remember the chemistry. What matters is that these aromas are fragile. They live in the hop oil and leave with steam, heat and oxygen. A late addition, a cool whirlpool and a gentle dry hop keep them.

A 20 litre pale ale to learn it on

Aim for an original gravity of 1.050 and 30 IBU. Use 92% pale malt and 8% Munich. Mash at 66 °C for 60 minutes. Ferment with a clean American ale yeast at 18 °C.

• Bittering: 10 g of a clean 14% alpha hop at 60 minutes. At 28% utilisation that is 10 x 0.14 x 0.28 x 1,000 / 20 = 19.6 mg/L, about 20 IBU.
• 10 minute addition: 15 g of Styrian Wolf for a few IBU and early flavour.
• Whirlpool at 75 °C for 20 minutes: 40 g of Styrian Wolf.
• Dry hop for four days at 18 °C: 40 g of Styrian Wolf.

That puts 95 g of Wolf into the beer, a little under 5 g per litre. For a first run, it is enough to find the fruit without overdoing it.

Pairing Wolf with other pale ale hops

Wolf has enough character to carry a beer alone, so try it as a single hop first. When you blend, choose partners that fit the fruit. Amarillo reinforces the floral side. Palisade brings apricot and a grassy bite that dries the finish.

For a more European pale ale, split the whirlpool between Wolf and Loral. The elderflower note then reads as a deliberate part of a floral, restrained beer rather than a tropical accident.

Keeping it fresh at home

Most homebrewers lose hop aroma in the last few steps, not in the recipe. Cool the dry hop addition to fermenter temperature before adding the pellets. Add the hops gently, close the lid quickly and avoid opening the fermenter again. When you rack to a keg or bottles, move the beer under CO2 if you can. If not, keep splashing to a minimum.

Bottle-conditioned beers need extra care. A little oxygen goes in at filling. The warm conditioning period at 22 to 25 °C then ages hop aroma quickly. Aim for two weeks of conditioning and then refrigerate. In an Indian summer, you may want to condition in a cool room or a dedicated fridge set to 20 °C.

Smelling before you buy

Newer Slovenian varieties are grown in small quantities, so homebrew shops may stock only one or two lots a year. Ask for the harvest year and the alpha acid on the label. A pack with no harvest date is a risk with a delicate fruity hop. If a shop lets you, open a pack and smell it. Mango and stone fruit should be obvious. A smell of hay or old tea means the pack is tired.

Tasting Wolf honestly

Pour a small glass at 8 °C. Smell before tasting and name the first three things you notice. Write them down before you read any description. Then compare with a second sample from the same batch two weeks later. Aroma notes change. A homebrewer who writes things down learns which stage of the process changed them.

If mango disappears first and grass appears, the hop is ageing in the beer. If the mango never appears, your hop may be old, or your dry hop was too warm. Both are easy to fix on the next brew.

Where to go next

Once you have brewed a single hop Wolf pale ale, brew the same recipe with a different hop and compare. That habit is the fastest route to understanding hops. If you want the chemistry and process behind it, from oils to oxidation, we cover them in Advanced Brewing Science.

Common questions

What does Styrian Wolf taste like?

Mango, stone fruit and elderflower with some citrus peel.

Is Styrian Wolf good for bittering?

Its alpha acids are well above the noble hops, so it can bitter, but most brewers prefer to save it for late additions where the fruit survives.

How much Styrian Wolf for a 20 litre pale ale?

About 80 to 100 g across the late boil, whirlpool and dry hop is a good start, which is roughly 4 to 5 g per litre.
