Zusammenfassung
All-grain brewing replaces Malzextrakt with raw grain, giving you full control over flavor, body, and Gärung character. A typical first Brautag takes 5–6 hours. You need a Maischebottich, hot liquor tank, Sudkessel, thermometer, and a basic understanding of mashing, Läutern, and boiling. Expect a Sudhausausbeute of 60–70 % on your first attempt — that is perfectly normal. Dieser Leitfaden führt dich durch every step, from crushing your malt to pitching yeast, with a timing chart, equipment checklist, and the most common first-batch mistakes so you can avoid them.
Why Go Allkorn?
Extract brewing is a fine way to learn. But at some point, every Hobbybrauer feels the pull of Allkorn. The reasons are straightforward:
- Cost savings. Base malt costs roughly $0.80–$1.20 per pound versus $4–$8 per pound for Flüssigmalzextrakt.
- Recipe control. You choose the Schüttung, the Maischetemperatur, the mash duration. That means you control fermentability, body, and color with precision no extract kit can match.
- Freshness. Crushed malt used on Brautag produces Würze with a clean, grainy sweetness that pre-made extract cannot replicate.
If you have brewed a few extract batches successfully and understand basic Desinfektion, you are ready. For a detailed comparison of both methods, see our guide on All Grain Vs Extrakt-Brauen.

Step-by-Step Walkthrough
Step 1: Calculate and Heat Your Einmaischwasser
Strike water is the initial water you add to the Maischebottich. You need enough to achieve your target mash thickness — typically 1.25–1.5 quarts per pound of grain.
For 11 lb of grain at 1.33 qt/lb:
11 × 1.33 = 14.6 quarts ≈ 3.65 gallons
The Einmaischwasser temperature must be higher than your target Maischetemperatur because the cool grain will absorb heat. A common formula:
Strike Temp = (0.2 / R) × (T_mash − T_grain) + T_mash
Where R is the water-to-grain ratio in quarts per pound, T_mash is your target Maischetemperatur, and T_grain is the grain temperature (usually room temp, ~68 °F).
For a target mash of 152 °F with grain at 68 °F and R = 1.33:
(0.2 / 1.33) × (152 − 68) + 152 = 0.15 × 84 + 152 = 12.6 + 152 = 164.6 °F
Heat your Einmaischwasser to approximately 165 °F. For complete sparge volume calculations, see Nachgusswasser Calculation Guide.
Step 2: Mill Your Grain
If you own a grain mill, set the gap to 0.035–0.045 inches. You want the husks cracked open — not shredded into flour. Intact husks form the filter bed during Läutern. If the grain is too finely crushed, you will get a stuck sparge.
If your local homebrew shop (LHBS) offers milling, use it. Tell them it is for Allkorn Batch-Sparge; they will set the gap appropriately.
Step 3: Einmaischen (Mash In)
Add your Einmaischwasser to the Maischebottich first, then slowly pour in the grain while stirring. This prevents dough balls — clumps of dry grain surrounded by water that never convert properly.
Stir thoroughly for 2–3 minutes. Check the temperature. You should be within 1–2 degrees of your target. If you are low, add a small amount of boiling water. If you are high, stir and wait — temperature drops are easier to manage than temperature raises.
Close the Maischebottich lid and set a timer for 60 minutes.
Step 4: The Mash Rest
During the mash, enzymes in the malt — primarily alpha-amylase and beta-amylase — convert starches into fermentable sugars. Temperature determines the balance between fermentable and unfermentable sugars:
- 148–150 °F: More beta-amylase activity. Drier, more fermentable Würze.
- 152–154 °F: Balanced. Good body with moderate fermentability.
- 156–158 °F: More alpha-amylase dominance. Fuller body, less alcohol potential.
For this recipe, 152 °F produces a balanced pale ale. For a deep dive into enzyme activity and Maischetemperaturs, read Maischetemperatur Guide Enzyme Activity.
Check the temperature at 15 and 30 minutes. A well-insulated cooler Maischebottich typically loses only 1–2 °F over 60 minutes.
Step 5: Vorlauf
After the mash, open the spigot on your Maischebottich and collect the first runnings in a pitcher. The first Würze that comes out will be cloudy with grain particles. Gently pour it back on top of the grain bed. Repeat until the Würze runs reasonably clear — usually 1–2 quarts.
This step sets the grain bed as a filter, producing clearer Würze.
Step 6: Sparge
Läutern rinses residual sugars from the grain. Für deinen ersten batch, Batch-Sparge is the easiest method:
- Drain all first runnings into your Sudkessel.
- Add your pre-heated Nachgusswasser (168–170 °F) to the Maischebottich. For a 5-gallon batch, this is typically 3.5–4.5 gallons depending on your boil-off rate and grain absorption.
- Stir gently for 1–2 minutes.
- Let it settle for 10 minutes.
- Vorlauf again (1–2 quarts), then drain into your Sudkessel.
You should now have approximately 6.5–7 gallons of Würze in your kettle (accounting for a 60-minute boil-off of about 1–1.5 gallons).
Step 7: The Boil
Bring the Würze to a vigorous, rolling boil. Watch for the Heißtrub — a foam of coagulated proteins that forms in the first 5–10 minutes. It can cause a boil-over if you are not paying attention. Reduce heat briefly or spray with cold water if foam rises to the rim.
Follow your Hopfenplan:
- At 60 minutes remaining: Add 1 oz Cascade (bittering).
- At 5 minutes remaining: Add 1 oz Cascade (flavor/aroma).
- At 15 minutes remaining (optional): Add 1 Whirlfloc tablet or 1 tsp Irish moss for clarity.
Step 8: Chill the Wort
After the boil, cool the Würze to your yeast’s Anstelltemperatur as fast as possible. For US-05, that is 64–68 °F.
- Immersion chiller: 20–30 minutes.
- Ice bath: 40–60 minutes. Put your kettle in a sink or tub filled with ice and water.
Fast chilling reduces the risk of contamination and promotes a good Kühltrub (protein precipitation that improves beer clarity).
Step 9: Transfer, Aerate, Pitch
Transfer the cooled Würze to your desinfiziert Gärbehälter. Leave the trub (sediment) behind in the kettle. Splash the Würze during transfer or shake the Gärbehälter for 2–3 minutes to introduce oxygen — yeast need it for healthy reproduction during the lag phase.
Sprinkle the Trockenhefe on top, or rehydrate per the manufacturer’s instructions. Seal the Gärbehälter with an Gärspund.
Step 10: Gärung
Place the Gärbehälter in a location where the temperature stays in the 64–68 °F range. You should see Gärspund activity within 12–24 hours. Primary Gärung typically takes 7–14 days for an American pale ale.
Take a Stammwürzewert at day 10 and again at day 14. If the readings are stable, Gärung is complete.
Häufige Fehler beim ersten Sud
1. Not Measuring Einmaischwasser Temperature Accurately
A cheap kitchen thermometer can be off by 5–10 degrees. Invest in a calibrated digital thermometer. An inaccurate Maischetemperatur means poor conversion.
2. Crushing Grain Too Fine
Flour-like crush leads to a stuck sparge. You will stand there for 45 minutes watching nothing drain. Aim for cracked husks with starchy endosperm exposed — not powder.
3. Forgetting to Account for Dead Space
Every Maischebottich has dead space below the false bottom or pickup tube. That volume of water never reaches your kettle. Measure it and add it to your water calculations.
4. Läutern with Water That Is Too Hot
Sparge water above 175 °F extracts tannins from grain husks, producing astringent flavors. Keep Nachgusswasser at 168–170 °F.
5. Boil-Over Panic
The Heißtrub is coming. Watch for it. Have a spray bottle of cold water ready. Do not walk away from the kettle during the first 10 minutes of the boil.
6. Expecting Extract-Level Efficiency
Your first Allkorn batch will likely hit 60–70 % Sudhausausbeute. That is fine. Extract brewers effectively work at 100 % efficiency because the manufacturer has already done the conversion. Adjust your Schüttung upward if your gravity is low — this is a normal learning curve.
7. Skipping Desinfektion Post-Boil
Everything that touches Würze after the boil must be desinfiziert. This rule does not change just because you are now an Allkorn brewer. If anything, you have more equipment to sanitize.
Efficiency: Setting Realistic Expectations
Brewhouse efficiency measures how much of the available sugar in your grain ends up in the Gärbehälter. The theoretical maximum extract from 2-row malt is about 37 points per pound per gallon (PPG).
For 10 lb of 2-row in 5 gallons:
Theoretical OG = (10 × 37) / 5 = 74 points → 1.074
At 70 % efficiency:
Actual OG = 1.074 × 0.70 = 1.052
That is exactly in our target range. If you hit 1.048, you are at about 65 % — perfectly acceptable for a first attempt. Track your efficiency over multiple batches. It will improve as you refine your process.
Troubleshooting Quick Reference
| Problem | Wahrscheinliche Ursache | Fix |
|---|---|---|
| Low OG | Low efficiency, too much Nachgusswasser | Reduce sparge volume, crush finer (slightly), extend mash |
| Stuck sparge | Too-fine crush, no rice hulls | Add rice hulls (0.5 lb), stir grain bed, reset |
| Astringent flavor | Sparge water too hot or pH > 6.0 | Monitor sparge temp and pH |
| Cloudy Würze | Poor vorlauf, fast sparge | Vorlauf longer, drain slower |
| Off-flavors (DMS) | Insufficient boil vigor, lid on during boil | Full rolling boil, lid off, minimum 60 min |
What Comes Next
Your first Allkorn batch will teach you more than a dozen extract batches. Once you are comfortable with the basic single-infusion mash, explore:
- Step mashing for beers with adjuncts like wheat or oats.
- Decoction mashing for traditional German and Czech lagers.
- Water chemistry adjustments to match regional profiles.
Each of these techniques builds on the fundamentals you practiced today.
