Paulaner Hefe-Weißbier is the benchmark German hefeweizen, the beer that defines the style for most homebrewers worldwide. Getting the banana-to-clove ratio right is the single most important challenge in cloning it, and that ratio is controlled almost entirely by fermentation temperature rather than recipe variables. I’ve brewed this clone dozens of times and can give you the exact process control that produces the Paulaner character.
Paulaner Hefe-Weißbier clone recipe (5 gallon / 19L batch)
Target stats: OG 1.052, FG 1.012, ABV ~5.5%, IBU 14, SRM 4–6, hazy pale gold. Grain bill: 5.5 lbs (2.49 kg) German wheat malt (Weizenmalz), at least 50% wheat malt is required by German law for Weizenbier; Paulaner typically uses 60–65% wheat. The wheat provides the distinctive grainy-tangy character and the proteins that create the permanent haze and dense foam. 3.5 lbs (1.59 kg) German Pilsner malt, base malt foundation, enzyme source for converting the wheat. 0.25 lb (113g) acidulated malt, mash pH management, helps efficiency with the wheat-heavy grain bill. Hops: 0.75 oz Hallertau Mittelfrueh or Hallertau Tradition (60 min), 13–15 IBU. No late hops. Hefeweizen is not a hop-forward style; the hops exist only to provide enough bitterness to balance the malt. Yeast, the most critical variable: Wyeast 3068 Weihenstephan Weizen is the industry-standard hefeweizen yeast and produces the most authentic banana/clove balance of any commercially available strain. White Labs WLP300 Hefeweizen Ale is the equivalent. Both are derived from the Weihenstephan strain that originated at the world’s oldest brewery. Fermentation temperature, controls the banana-to-clove ratio: Lower fermentation temperature (16–18°C / 61–64°F): produces more clove (4-vinylguaiacol / 4VG), less banana (isoamyl acetate). Result: spicy, dry, clove-forward character. Higher fermentation temperature (20–22°C / 68–72°F): produces more banana, less clove. Result: fruity, soft, banana-forward character. Paulaner Hefe-Weißbier has a balanced banana-clove profile leaning slightly banana, ferment at 18°C (64°F) and allow to rise naturally to 20°C (68°F) during active fermentation. Ferulic acid rest (optional but recommended): Mash at 43°C (109°F) for 15 minutes before raising to saccharification temperature, this creates ferulic acid that the yeast converts to 4VG (clove phenol) during fermentation. Without this rest, clove character is reduced; with it, you can dial in the banana-clove balance. Water: Soft, low-mineral, calcium 40 ppm, sulfate 20 ppm, chloride 60 ppm. Munich water is naturally soft. Process: Step mash: 43°C (109°F) for 15 minutes (ferulic acid rest), 52°C (126°F) for 10 minutes (protein rest, important for wheat-heavy bills), 67°C (153°F) for 45 minutes (saccharification), 76°C (169°F) mash out. 60-minute boil. Do not filter, hefeweizen requires natural yeast haze. When serving from a bottle, swirl the last 20ml to resuspend yeast sediment before pouring into glass. Carbonate to 3.0–3.5 volumes CO2 for the characteristic dense hefeweizen foam.
Common Questions
Why does my hefeweizen taste like pure banana and no clove?
Excessive banana (isoamyl acetate) at the expense of clove (4-vinylguaiacol) in hefeweizen is caused by too-warm fermentation, under-pitching (stressed yeast produces more isoamyl acetate), or skipping the ferulic acid rest. Isoamyl acetate is an ester produced by yeast under stress, at warm temperatures, and during rapid early fermentation. If your hefeweizen smells like Runts candy rather than banana-and-spice: first, check your fermentation temperature, dropping to 16–17°C (61–63°F) in the first 48 hours of fermentation significantly reduces ester production. Second, pitch adequate yeast, for a 1.052 OG hefeweizen at 16°C (61°F), you need 175–200 billion viable cells. Under-pitching stresses the yeast and dramatically increases isoamyl acetate. Third, add the ferulic acid rest (43°C / 109°F for 15–20 minutes) to increase the 4VG precursor that will balance the banana with clove. The banana note in hefeweizen should be pleasant and complementary to the clove, not overwhelming and artificial-smelling. A well-balanced Paulaner clone should pass the “Runts test”, if it smells like candy rather than fresh banana alongside clove/pepper spice, the fermentation temperature was too high or the pitch rate too low.
