Hopper weather between red canyon walls
A 5.6% harvest ale for the South Fork Boise, toasty and malty, poured at the end of a long autumn float.
Brewed to order
South Fork Boise Harvest Ale carries a striped label with a grasshopper and an ant drawn at its foot. The bands run rust red, salmon, sandstone and juniper green beneath black serif letters.

Stripes stacked like canyon rock. Rust red, sandstone, juniper green, with old serif letters across each band. At the bottom, a grasshopper and an ant, the two bugs you tie on when the light goes low in autumn. Behind it, moss on grey stone and pines on the rim.
It drinks like toast with a thin coat of caramel. Nutty through the middle, earthy at the end, dry enough for a second. Open one when the waders are hanging and the rods are broken down.
Mash temperature carries this one. Hold 154°F for the full hour and the Maris Otter and biscuit keep their weight. Drift low and the body thins out like a nymph rig with too little tungsten.

Grain bill
5 malts · 11.88 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 |
|---|---|---|---|---|
| Maris Otter | 75.8% | 2.25 lb (1.02 kg) | 9 lb (4.08 kg) | 27 lb (12.25 kg) |
| Munich | 12.6% | 6 oz (170 g) | 1.5 lb (0.68 kg) | 4.5 lb (2.04 kg) |
| Crystal 60L | 6.3% | 3 oz (85 g) | 12 oz (340 g) | 2.25 lb (1.02 kg) |
| Biscuit | 4.2% | 2 oz (57 g) | 8 oz (227 g) | 1.5 lb (0.68 kg) |
| Pale chocolate | 1.1% | 0.5 oz (14 g) | 2 oz (57 g) | 6 oz (170 g) |
| Total grain | 100% | 2.97 lb (1.35 kg) | 11.88 lb (5.39 kg) | 35.63 lb (16.16 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 |
|---|---|---|---|---|---|
| East Kent Goldings | Boil | 60 min | 7.1 g (0.25 oz) | 28 g (1 oz) | 85 g (3 oz) |
| Fuggle | Boil | 15 min | 7.1 g (0.25 oz) | 28 g (1 oz) | 85 g (3 oz) |
| Cascade | Boil | Flameout | 7.1 g (0.25 oz) | 28 g (1 oz) | 85 g (3 oz) |
Yeast and pitch
London ESB English ale yeast · 1 dry pack for 5 gal
London ESB English ale yeast. Pitch at 64°F.
| Yeast | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|
| London ESB English ale yeast | 1 dry pack | 1 dry pack | 3 dry 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
8.2 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 | 2.14 gal (8.1 L) | 8.2 gal (31 L) | 20.1 gal (76.1 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 | 0.24 gal (0.9 L) | 0.95 gal (3.6 L) | 2.85 gal (10.8 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 Moderate carbonate with a little more chloride than sulfate rounds the malt and keeps the finish soft.
Mash
154°F · 60 min
The mash turns starch into sugar. Hold the temperature steady and the beer finishes the way the recipe intends.
- Rest154°F for 60 minutes
- Strike waterHeat to 164°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 warmer rest leaves body for the toasted malt to sit on
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
2.3 volumes CO₂ · bottle or keg

Target 2.3 volumes of CO₂.
| Bottling | 12-pack batch · 1.25 gal | Classic · 5 gal | 12×12 batch · 15 gal |
|---|---|---|---|
| Corn sugar to prime | 0.97 oz (28 g) | 3.89 oz (110 g) | 11.68 oz (331 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 69°F, the warmest the beer got while it fermented.
Kegging Set the regulator to 9.1 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
- Weigh the pale chocolate twice; a little extra turns autumn amber into brown.From the recipe
- Let the temperature rise on day seven so the yeast finishes dry.From the recipe
- Keep the Cascade at flameout modest; it should hint, not lead.From the recipe
