Azacca hops for mango and citrus in a single hop IPA

What Azacca is

Azacca is a modern American hop released in the mid 2010s. It is high in alpha acid, commonly quoted around 13 to 16%, though crops differ.

The aroma is tropical: mango above all, with orange, tangerine, pineapple and a touch of pine. It is cleaner and less dank than some of its neighbours, which makes it a good fit when you want fruit without a heavy resin edge.

Because the alpha is high you can bitter with it, but this wastes the best part. The oils that carry the mango are volatile and a long boil drives them off.

Why brew a single hop IPA

A single hop beer teaches you more than a blend. When only one hop is in the beer, every note belongs to it, so you learn what the hop does at each stage. Blends can hide a weak hop or a wasteful schedule.

Keep everything else simple. A pale base, a clean yeast and soft water let the hop show. Our guide on Olicana hops shows another mango-leaning hop in an English style. Tasting the two side by side is a good exercise.

A 20 litre recipe

This recipe aims for an original gravity near 1.062 and about 30 IBU. Brewhouse efficiency varies, so adjust the grain to hit your own number.

• Pale ale malt 5.4 kg (90%).
• Dextrin malt 0.3 kg (5%).
• Wheat malt 0.3 kg (5%).
• Azacca 20 g at 60 minutes, for around 30 IBU.
• Azacca 50 g in the whirlpool at 80 °C for 20 minutes.
• Azacca 40 g as a dry hop at day three of fermentation, then a second 40 g for the last three days.

Mash at 66 °C for 60 minutes. Ferment with a clean American ale yeast at 18 to 19 °C, then crash and package. The dextrin and wheat malt add body and foam, which helps hold the hop aroma in the glass.

If you want less bitterness, drop the 60 minute addition to a small charge and rely on the whirlpool. Taste the next batch and compare.

Whirlpool and dry hop timing

Whirlpool temperature changes what you get. Hotter whirlpools extract more bitterness and less delicate aroma. Cooler ones (nearer 70 °C) keep more of the fruit. Try one batch at 80 °C and another at 70 °C and write down the difference.

Dry hopping during active fermentation, sometimes called a biotransformation addition, lets yeast alter some hop compounds and can raise tropical fruit notes. The effect is real but depends on the yeast and the timing. Use it as an experiment, not a rule.

The second dry hop, added when fermentation is nearly done, gives the fresh top note. Keep contact to about three days. Longer than that and you risk grass and vegetal flavours.

Heat, haze and hop burn

In an Indian summer, a fermenter on the floor can reach 28 to 30 °C. At that temperature yeast makes fruity esters and fusel notes that fight the hop. A chest freezer with a controller is the single best upgrade for a homebrewer here. Without one, brew in the cooler months or ferment in a water bath with ice bottles.

Big dry hop loads can leave a harsh, scratchy sensation sometimes called hop burn. Cold conditioning and a few days to settle help. Do not rush a hoppy beer into bottles while it is still full of hop particles.

Oxygen ruins hoppy beer faster than anything else. Transfer closed if you can, purge kegs or bottles and keep the beer cold. A hoppy beer that sits warm for a week is no longer the beer you brewed.

Buying and storing Azacca in India

Pellets are the common form. Check the harvest year and buy foil packs sealed under nitrogen or vacuum. Freeze them. Use opened packs within a few weeks, or reseal and freeze again. Aroma oils fade far faster than alpha acid, so stale hops still bitter and give you little mango.

If you want to understand why oils behave this way, our piece on why one hop smells of mango and another of pine explains the chemistry in plain terms. For concentrated forms, see hop extracts and cryo hops.

From recipe to understanding

Brewing this beer twice with one change each time will teach you more than a stack of recipes. The next step is knowing why a change worked, which means understanding hop oil chemistry and extraction. That is the point at which you start designing beers instead of copying them.

Common questions

What does Azacca taste like?

Mango above all, with orange, tangerine, pineapple and a little pine. It is bright and clean rather than dank.

Is Azacca good for bittering?

It has high alpha acid so it can bitter, but the best of the aroma is lost in a long boil. Most brewers use a neutral hop for bittering.

How much Azacca should I use in an IPA?

For a 20 litre IPA, roughly 150 g in total across a small bittering addition, a whirlpool and a dry hop is a sensible start. Adjust to taste.

How do I store Azacca hops?

Keep sealed packs in the freezer and use opened packs quickly. Aroma fades faster than bitterness.
