How to brew Rauchbier beer at home is a question that sounds intimidating — smoked malt, lagering temperatures, and a style defined by one of the world’s most assertive flavor profiles — but the process is actually more approachable than its reputation suggests. Rauchbier is a straightforward amber lager in structure; what sets it apart is entirely the malt, and once you understand how to work with smoked malt, the brewing process is familiar territory for any intermediate homebrewer. The main challenges are sourcing quality beechwood-smoked malt, maintaining cold lagering temperatures, and calibrating smoke intensity to your taste. Grain to glass, expect approximately 10–14 weeks.

Ingredients
Grain Bill
| Grain | Amount | Contribution |
|---|---|---|
| Weyermann Beechwood Smoked Malt (affiliate link) | 3.5 kg (7.7 lb) | Core smoke character, base fermentables, malt backbone |
| Weyermann Munich Malt Type I (affiliate link) | 1.0 kg (2.2 lb) | Bread, biscuit malt sweetness; body |
| Weyermann Carafa Special Type I (dehusked) (affiliate link) | 150 g (5.3 oz) | Color enhancement, mild roasty depth without harsh bitterness |
| Weyermann Caramunich Type II (affiliate link) | 250 g (8.8 oz) | Caramel sweetness, body, red-amber color |
Sourcing note: Weyermann is the most accessible producer of authentic beechwood-smoked malt internationally. Their smoked malt is kilned over beechwood in Bamberg — the same style of production used by Schlenkerla’s own maltings. For homebrewers outside Europe, MoreBeer (affiliate link) and Northern Brewer (affiliate link) stock Weyermann smoked malt in the US; in the UK, The Malt Miller (affiliate link) carries it regularly.
Smoke intensity note: This recipe uses smoked malt at approximately 72% of the grain bill, which produces an assertive but not overwhelming smoke character comparable to a mid-range Schlenkerla. To dial back the smoke, reduce smoked malt to 50% and increase Munich Malt proportionally. For a full Schlenkerla-level intensity, increase smoked malt to 90% and reduce Munich Malt to a supporting role.
Hops
| Hop | Amount | Timing | IBU Contribution | Purpose |
|---|---|---|---|---|
| Hallertau Mittelfrüh (4% AA) (affiliate link) | 40 g (1.4 oz) | 60 min | 22 IBU | Bittering, noble herbal character |
| Tettnanger (4.5% AA) (affiliate link) | 15 g (0.5 oz) | 15 min | 6 IBU | Floral, spicy noble aroma |
Note: Rauchbier is not a hop-forward style. The hop additions here serve two purposes: providing enough bitterness to balance the malt sweetness (around 26 IBU total), and contributing the subtle herbal and spicy notes characteristic of Franconian lagers. Do not be tempted to increase hop rates — the smoke is the star, and heavy hopping will compete with it unpleasantly.
Adjuncts
None required. Rauchbier is a malt-focused style with no traditional adjuncts. If you are brewing a Bamberg-style Kellerbier variant, you might add a small amount of wheat malt (5–10%) for additional haze and body, but for the classic Märzen-style Rauchbier, the grain bill above is complete.
Yeast
Choose one of the following — not both:
Option A: Wyeast 2206 Bavarian Lager (affiliate link) — The standard recommendation for this style. Produces a clean, malt-forward lager profile with excellent attenuation and a subtle sulfur note during fermentation that will clean up during lagering. Ferment at 9–11°C (48–52°F). This is the yeast most consistent with classic Franconian lager character.
Option B: White Labs WLP833 German Bock Lager (affiliate link) — Slightly fuller-bodied than WLP820, with a clean, smooth malt profile and good attenuation. An excellent alternative if Wyeast 2206 is unavailable. Ferment at 9–11°C (48–52°F); WLP833 tolerates up to 13°C (55°F) if needed. This yeast suits the malt richness of the style well.
Both options require a healthy yeast starter. For a 20-liter (5.3-gallon) batch at 1.052 OG, a 2-liter starter is a reasonable baseline — but verify your required cell count using a pitch rate calculator such as Yeast Calc or Brewer’s Friend, since actual starter size depends on yeast package viability and age. Build the starter 24–48 hours before brew day using approximately 200 g (7 oz) of dry malt extract in 2 liters (0.5 gallons) of water.
Equipment
Beyond a standard homebrewing setup, Rauchbier requires:
- Temperature-controlled fermentation chamber (affiliate link) — Lager fermentation at 9–11°C (48–52°F) requires dedicated temperature control. A chest freezer with an Inkbird temperature controller (affiliate link) is the most cost-effective solution for most homebrewers.
- Large yeast starter vessel (2L Erlenmeyer flask) (affiliate link) — Lager yeast requires a much larger pitch rate than ale yeast; underpitching is the single most common cause of off-flavors in homebrewed lagers.
- Auto-siphon and transfers kit (affiliate link) — For transferring beer cleanly without oxygen pickup during the lagering phase.
How to Brew Rauchbier Beer: The Process Step by Step
Step 1 — Mash: Heat 14 liters (3.7 US gallons) of strike water to 70°C (158°F). Add the grain bill and stir thoroughly to avoid dough balls, targeting a mash temperature of 67°C (153°F). Hold at 67°C (153°F) for 60 minutes. This slightly higher mash temperature retains some residual sweetness and body, which balances the drying quality of the smoke. A lower mash temperature (64–65°C / 147–149°F) will produce a drier, thinner beer where the smoke becomes more angular and less integrated — avoid this unless you specifically want a dry, crisp expression.
Step 2 — Mash-out and lauter: Raise the mash temperature to 76°C (169°F) for 10 minutes to halt enzymatic activity and improve lautering flow. Vorlauf (recirculate) until the runoff runs clear, then collect the first wort. Sparge with 76–78°C (170–172°F) water to collect a total pre-boil volume of approximately 25 liters (6.6 US gallons), targeting a pre-boil gravity of around 1.042.
Step 3 — Boil: Bring wort to a vigorous full boil. Total boil time: 90 minutes. The extended boil reduces DMS (dimethyl sulfide) precursors, which are more common in lager malts. Add hops as follows:
- At 60 minutes remaining: Hallertau Mittelfrüh (40 g / 1.4 oz)
- At 15 minutes remaining: Tettnanger (15 g / 0.5 oz)
- At 15 minutes remaining: Add Whirlfloc tablet or Irish Moss for clarity
Step 4 — Chill and pitch: Chill the wort rapidly to 9°C (48°F) using an immersion chiller or counterflow chiller. Rapid chilling produces a clean cold break, improving lager clarity. Transfer to a sanitized fermenter, aerate well (oxygen is your friend at pitching — lager yeast needs it), and pitch the prepared yeast starter. Good aeration at this stage is critical for healthy lager fermentation; consider using an aquarium pump and diffusion stone for 30–45 minutes.
Step 5 — Fermentation: Ferment at 9–11°C (48–52°F) for 3–4 weeks. Primary fermentation will be slow and steady — lager yeast operates on a different timescale than ale yeast, and patience is essential. You will likely see minimal krausen activity compared to an ale. Do not be alarmed by a slight sulfuric smell during active fermentation; this is normal for Bavarian lager strains and will dissipate during lagering.
When fermentation is approximately 75% complete (around 1.020–1.022 for this recipe), perform a diacetyl rest: raise the temperature to 14–16°C (57–61°F) for 48–72 hours. This encourages the yeast to reabsorb diacetyl, a buttery off-flavor compound that lager yeast produces early in fermentation. Skipping the diacetyl rest is the most common cause of butter character in homebrewed lagers.
Step 6 — Cold crash and lager: After the diacetyl rest, slowly lower the temperature to 0–2°C (32–36°F) over 2–3 days. Hold at lagering temperature for a minimum of 4 weeks. Six to eight weeks is better. The lagering phase is not optional for a serious Rauchbier — it softens the smoke character, integrates the malt flavors, and drops the beer brilliantly clear. Extended lagering also allows volatile sulfur compounds to dissipate. Patience here is rewarded.
Step 7 — Package: Transfer to a keg or bottles. For bottle conditioning, target 2.3 volumes CO₂. Use a priming sugar calculator for your exact batch volume and temperature — do not guess. Residual CO₂ levels, beer temperature, and batch volume all affect the result significantly; a calculator (such as the one at BrewUnited or Brewer’s Friend) is the only reliable method. For kegging, force carbonate at 10 psi (0.7 bar) at 3°C (37°F) for 7–10 days, or use a set-and-forget approach at serving pressure.
Allow bottle-conditioned Rauchbier at least 3–4 weeks of conditioning at cellar temperature (12–14°C / 54–57°F) before drinking. Then chill and serve.

Troubleshooting
Smoke too harsh or acrid: This is usually a grain crush or extraction issue rather than an inherent problem with smoked malt. Over-sparging can extract harsh phenolic compounds from smoked malt at higher rates than from regular malt. Keep sparge water below 78°C (172°F) and stop sparging before the runoff drops below 1.010. If the harshness persists batch to batch, reduce smoked malt percentage and extend lagering time — lagering integrates and softens smoke character significantly.
Not enough smoke character: If the beer is tasting more like a Märzen than a Rauchbier, the smoked malt percentage is likely too low, or the malt you sourced is older and has lost smoke intensity. Fresh smoked malt from a recent maltings batch will be substantially more assertive than year-old stock. Increase smoked malt to 80–90% of the grain bill in your next batch. Store smoked malt sealed — it loses volatiles over time.
Buttery or butterscotch flavor (diacetyl): The most common off-flavor in homebrewed lagers. Cause: yeast did not complete diacetyl reabsorption during fermentation. Solution: always perform a diacetyl rest at 14–16°C (57–61°F) for at least 48 hours before cold-crashing. A warm conditioning period post-fermentation can also help if the beer is already packaged — bring it to 16°C (61°F) for a week, then re-chill.
Sulfuric aroma (rotten eggs / struck match): Common in Bavarian lager strains during fermentation and usually dissipates with time. If sulfur persists into the finished beer, it indicates insufficient lagering time or oxygen pickup during transfer. Extend lagering and ensure all transfer equipment is sanitized and oxygen exposure is minimized.
Beer is cloudy after lagering: Extended lagering at 0–2°C (32–36°F) should drop a well-brewed Rauchbier brilliantly clear. Persistent haze after 6+ weeks usually indicates chill haze (protein-polyphenol complex), which can be addressed by adding Whirlfloc during the boil on future batches. You can also fine with gelatin at the start of cold-crashing: dissolve 1 tsp gelatin in 100 ml (3.4 fl oz) of warm water and add to the fermenter just before cold-crashing.
Thin body and mouthfeel: Cause: mash temperature too low. Mashing Rauchbier below 65°C (149°F) can produce a dry, thin beer. Maintain 67°C (153°F) strictly. If the issue persists, consider adding 200 g (7 oz) of Carapils/Carafoam to future batches for additional body and head retention.
Variations to Try
Helles Rauchbier (Lighter Smoke): Reduce smoked malt to 30–40% and replace the remainder with Pilsner malt (instead of Munich). Drop the Carafa and Caramunich entirely. The result is a pale lager with a subtle smoke presence — closer to Brauerei Spezial’s expression than Schlenkerla’s. Ideal for introducing friends to the style who are intimidated by full-intensity Rauchbier.
Rauchbier Bock: Scale the grain bill up by 30–40% to target an OG of 1.066–1.074. Increase the Munich Malt proportion to 40% and keep the smoked malt at 50–60%. The higher gravity and extended lagering (12+ weeks) will produce a richer, more warming beer — a version of the seasonal Urbock that Schlenkerla releases each autumn.
Cherry Wood or Alder Smoke Experiment: Substitute cherry wood-smoked malt or alder-smoked malt (available from specialist maltsters) for the beechwood smoked malt at the same percentages. This explores how different wood species change the smoke character: cherry wood tends toward fruity, resinous smoke; alder is lighter and sweeter. A useful comparative exercise for understanding the role of specific fuel in malt character.
Smoked Dunkel: Keep the base recipe but add 300 g (10.6 oz) of Carafa Special Type III and reduce smoked malt to 60%. The result is a darker, more chocolatey beer with smoke woven through a roastier malt profile. Think Rauchbier crossed with a Munich Dunkel — a genuinely satisfying cold-weather beer.
Mixed Fermentation Rauchbier: For the adventurous: after primary lager fermentation is complete, transfer 10% of the batch to a separate vessel and add a small pitch of Lactobacillus. Allow to sour for 3–5 days at 38°C (100°F), then blend back into the main batch before lagering. The resulting beer has a subtle tartness that amplifies the savory smoke character in an unexpected way — not traditional, but genuinely compelling.
Brewing Rauchbier is one of those projects that rewards patience far more than technical complexity. The hard work is in the waiting — the long lager, the careful cold-crash, the weeks of conditioning that transform a harsh, smoky young beer into something smooth and integrated. Every week of lagering pays dividends in the glass.
