Henry's Fork Twin Trout Kölsch
by @sunny
Mist lifting off a quiet trout run
An amber Kölsch named for Henry's Fork, crisp and lightly hopped at 4.9%, for slow evenings on the riverbank.
Brewed to order
Henry's Fork Twin Trout Kölsch carries two rainbow trout circling through curling river water on its label. The label is pale gold, with pink-striped fish and waves in deep green and cream.

Bready malt and soft caramel, a peppery lift of noble hops, then a clean, dry snap.
- Serve
- 40°F in a tall, narrow glass
- Alongside
- grilled trout, soft pretzels with mustard, fresh bratwurst
Two rainbow trout chase each other round the label, pink flanks and speckled green backs riding curls of cream water. Behind them, mist hangs low over Henry's Fork and dark pines line the far bank.
It pours amber. Bready malt and a touch of caramel come first, then a peppery note from Tettnang and a clean, dry finish. Open one when the evening hatch is winding down and the water goes still.
Cold conditioning is where this one comes together. Three weeks at 34°F lets the Kölsch yeast settle and rounds off the crystal malt, so give it the time before you pour.

Grain bill
5 malts · 9.38 lb for 5 gal

Milled grain, weighed for each batch size. The percentage is each malt's share of the grist and stays the same at every size.
| Malt | % of grist | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|---|
| Pilsner malt | 61.3% | 1.44 lb (0.65 kg) | 5.75 lb (2.61 kg) | 17.25 lb (7.82 kg) |
| Munich malt | 16% | 6 oz (170 g) | 1.5 lb (0.68 kg) | 4.5 lb (2.04 kg) |
| Vienna malt | 8% | 3 oz (85 g) | 12 oz (340 g) | 2.25 lb (1.02 kg) |
| Crystal 60 | 10.7% | 4 oz (113 g) | 1 lb (0.45 kg) | 3 lb (1.36 kg) |
| Crystal 120 | 4% | 1.5 oz (43 g) | 6 oz (170 g) | 1.13 lb (0.51 kg) |
| Total grain | 100% | 2.34 lb (1.06 kg) | 9.38 lb (4.25 kg) | 28.13 lb (12.76 kg) |
Hop schedule
3 additions · 90 min boil

Pellet hops, weighed in grams. Boil times count down to the end of the boil, so 60 minutes means the first thing in the kettle.
| Hop | Use | Time | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|---|---|
| Hallertau Mittelfrüh | Boil | 60 min | 11 g (0.38 oz) | 43 g (1.5 oz) | 128 g (4.5 oz) |
| Tettnang | Boil | 15 min | 7.1 g (0.25 oz) | 28 g (1 oz) | 85 g (3 oz) |
| Tettnang | Boil | Flameout | 3.5 g (0.13 oz) | 14 g (0.5 oz) | 43 g (1.5 oz) |
Yeast and pitch
Wyeast 2565 Kölsch · 1 liquid pack for 5 gal
Wyeast 2565 Kölsch. Pitch at 60°F.
| Yeast | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|
| Wyeast 2565 Kölsch | 1 liquid pack | 1 liquid pack | 3 liquid packs |
One pack per 5 gal, and one more above 1.060 OG in a batch over 3 gal. Never fewer than one. House guidance
Water
8.63 gal into the mash for 5 gal
Full-volume brew-in-a-bag: all the water goes in at the start and there is no sparge. Volumes are the total to heat, so the kettle has to hold the mash and still leave room to boil: the 12-pack kit sells a 5 gal stockpot and the 12×12 kit a 30 gal kettle for that.
| Water | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|
| Into the mash | 2.34 gal (8.8 L) | 8.63 gal (32.6 L) | 20.13 gal (76.2 L) |
| Boiled off | 0.75 gal (2.8 L) | 1.88 gal (7.1 L) | 1.88 gal (7.1 L) |
| Held by the grain | 0.19 gal (0.7 L) | 0.75 gal (2.8 L) | 2.25 gal (8.5 L) |
| Left as trub | 0.15 gal (0.6 L) | 1 gal (3.8 L) | 1 gal (3.8 L) |
| Into the fermenter | 1.25 gal (4.7 L) | 5 gal (18.9 L) | 15 gal (56.8 L) |
Boil-off, grain absorption and trub are typical figures for a stovetop pot and a propane kettle, not measurements of your own gear. Brew once, note what you end up with, and adjust. House guidance
Water profile Soft water with low sulfate and a gentle chloride lean keeps the malt round and the finish clean.
Mash
150°F · 60 min
The mash turns starch into sugar. Hold the temperature steady and the beer finishes the way the recipe intends.
- Rest150°F for 60 minutes
- Strike waterHeat to 160°F; the grain cools it to the rest temperature. House guidance
- Mash-outRaise to 168°F and hold 10 minutes, then lift and drain the bag. House guidance
- Mash ina cooler rest keeps the finish dry.
Boil
90 min · 3 hop additions
Hops go in on a countdown from the end of the boil. Early additions give bitterness; late ones give aroma.

Fermentation
3 steps · first pint in 35 days

The recipe's own schedule, in order. Temperature control matters more than almost anything else on this page.
- 10 days at 60°F
- 3 days at 65°F for a diacetyl rest
- 3 weeks at 34°F
First pint 35 days from brew day.
Packaging and carbonation
2.6 volumes CO₂ · bottle or keg

Target 2.6 volumes of CO₂.
| Bottling | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|
| Corn sugar to prime | 1.14 oz (32 g) | 4.54 oz (129 g) | 13.62 oz (386 g) |
| 12 oz bottles it fills | 12 | 50 | 144 |
Dissolve the sugar in a little boiled water, stir it gently into the beer, then bottle. The amount is worked out for 65°F, the warmest the beer got while it fermented.
Kegging Set the regulator to 12.3 psi at 38°F.
Kegging instead Skip the bottles with 3 × 5 gal ball-lock kegs, 1 × 5 lb CO₂ tank, 1 × dual-gauge regulator, 1 × gas and beer lines with picnic taps: the kegging upgrade for the 15 gal home brewery, $594.
Brewer's notes
4 tips
- Weigh the crystal malts carefully; a few extra ounces push the colour and sweetness too far.From the recipe
- Pitch a healthy starter so the cool ferment begins within a day.From the recipe
- Hold the diacetyl rest even if the gravity looks finished; the yeast is still tidying up.From the recipe
- Let the cold rest run its full three weeks for a clear, polished pour.From the recipe
