Idaho 7 hops and their apricot and black tea character

A stone fruit hop with a tannic side

Idaho 7 is an American variety grown in the Pacific Northwest. Supplier sheets put its alpha acids in the low to mid teens, so it can bitter a beer as well as flavour it. Brewers describe the aroma as apricot, orange and tangerine over a resinous pine base, with a dry, tannic note like strong black tea.

The tea character is the interesting part. Used with care it adds depth and a dry finish to the fruit. Used heavily it turns a pale ale into something that tastes brewed rather than hopped.

A 20 litre pale ale built around it

Keep the grist plain so the hop shows. For 20 litres at about OG 1.055:

• Pale ale malt 4.2 kg (84%).
• Vienna malt 0.5 kg (10%).
• Light crystal malt around 30 EBC 0.3 kg (6%).

Mash at 66 °C for 60 minutes. The Vienna adds a little bread crust and the crystal rounds the finish without adding much sweetness. If you want to understand why we choose a base malt first, our guide to base malts covers the options. Ferment with a clean American ale yeast at 18 to 19 °C and aim for a final gravity near 1.012.

The hop schedule

Because the alpha is high, a small bittering charge goes a long way.

• 15 g at 60 minutes for roughly 20 IBU.
• 40 g in a whirlpool at 75 to 80 °C for 20 minutes.
• 60 g dry hop (3 g per litre) for three days near the end of fermentation.

Counting the whirlpool, a calculator will put the beer near 35 IBU. Remember that a whirlpool hop still adds bitterness even though the wort is below boiling. If the beer tastes sharper than planned, trim the whirlpool first.

Managing the tea

Tannins come from contact time and from the hop material itself. The more leaf matter you leave sitting in the beer, the more dry, tea-like grip you get. Three habits keep it in check.

• Take the dry hop out after three days. Do not leave it for a fortnight.
• Dry hop at fermentation temperature or slightly below, not warm.
• Rack off the trub and hop debris before packaging.

Water plays a part too. Very hard, high carbonate water makes hop tannin taste harsher and drier. If your borewell water is hard, dilute it with RO water so the mash lands at pH 5.2 to 5.5 before you blame the hop.

If you want the fruit without much tea, shift weight from the dry hop into the whirlpool and let the oils carry the aroma instead.

How it compares with similar hops

Idaho 7 sits near other fruity American varieties but has its own accent. Summit leads with tangerine and can turn savoury when stale. Superdelic goes for red berries in hazy beer. Idaho 7 is drier and more resinous than either. A small blend with a juicier hop, about one part in three, can soften its edges.

Using Idaho 7 in Indian conditions

Imported American hops spend weeks in transit and then in storage, often in a warm city. High alpha, high oil hops are more forgiving than delicate noble types, but the apricot is volatile and fades. Keep sealed packs in the freezer and open only what you need.

A simple check before brewing: steep 2 g of pellets in 200 ml of just-boiled water, cool it and smell. Apricot and orange mean the pack is good. Cheese or wet cardboard means the oils have oxidised, so use it for bittering only.

Learn it by repeating it

Brew the recipe twice. Keep everything the same except the dry hop: 60 g for three days in one batch and 60 g for ten days in the other. Taste both at two weeks. The difference in tea grip is the best lesson in hop contact time you can get at home.

That kind of controlled comparison is also where hop chemistry begins to explain what your tongue finds. Write down the dates, the alpha on the pack and the temperature at each step. When you taste, give the tea note a score from zero to five so that the difference is on paper and not only in your memory.

Common questions

What does Idaho 7 taste and smell like?

Apricot, orange and tangerine over a resinous pine base, with a dry black tea note. The tea becomes stronger with long contact time.

Is Idaho 7 a bittering or an aroma hop?

Both. The alpha is high enough to bitter a beer. Its oils also make it a good whirlpool and dry hop variety.

How much Idaho 7 should I dry hop with?

Around 3 to 5 g per litre for three to four days is a sensible range. Go higher and you risk a tannic, tea-like beer.

How do I stop a tea-like grip in my beer?

Shorten the dry hop contact time, rack off hop debris and move some of the aroma weight into a whirlpool addition.
