Henry's Fork Trout Kölsch
by @john
Mist lifting off flat water at sunrise
A Kölsch named for Henry's Fork, honeyed and crisp at 4.8%, for long mornings on the river and the evenings after.
Brewed to order
Henry's Fork Trout Kölsch shows a rainbow trout gliding over a bed of river stones beneath dark green lettering. The label is pale gold, with a pine at its edge, a pink stripe down the fish and teal water curling above it.

A rainbow trout cruises over round grey stones, its pink stripe catching the light. Dark green letters sit on a pale gold field, a lone pine stands at the edge, and behind it all the river breathes mist into the trees.
Bread crust and honey come first, then a soft caramel middle and a floral hop note. It finishes dry and clean. Open one when the rods are back in the truck and the light goes long.
Cold conditioning is the step to respect. Three weeks at 34°F lets the Kölsch yeast settle out and polishes the malt into something smooth.

Grain bill
4 malts · 9.56 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 | 68% | 1.63 lb (0.74 kg) | 6.5 lb (2.95 kg) | 19.5 lb (8.85 kg) |
| Munich malt | 20.9% | 8 oz (227 g) | 2 lb (0.91 kg) | 6 lb (2.72 kg) |
| Crystal 80 | 10.5% | 4 oz (113 g) | 1 lb (0.45 kg) | 3 lb (1.36 kg) |
| Carafa Special II | 0.7% | 0.3 oz (7 g) | 1 oz (28 g) | 3 oz (85 g) |
| Total grain | 100% | 2.39 lb (1.08 kg) | 9.56 lb (4.34 kg) | 28.69 lb (13.01 kg) |
Hop schedule
3 additions · 60 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 58°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
8.02 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 | 2.09 gal (7.9 L) | 8.02 gal (30.3 L) | 19.55 gal (74 L) |
| Boiled off | 0.5 gal (1.9 L) | 1.25 gal (4.7 L) | 1.25 gal (4.7 L) |
| Held by the grain | 0.19 gal (0.7 L) | 0.77 gal (2.9 L) | 2.29 gal (8.7 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 touch of chloride 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 and crisp
Boil
60 min · 3 hop additions
Hops go in on a countdown from the end of the boil. Early additions give bitterness; late ones give aroma.

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
3 tips
- Pitch a healthy starter; this yeast is slow to wake at cool temperatures.From the recipe
- The warm rest at 65°F lets the yeast clean up diacetyl before lagering.From the recipe
- Kölsch yeast stays cloudy for a long time; the cold weeks are where it clears.From the recipe
