Brewing Wheat Beer: Hefeweizen, Witbier, and American Wheat Explained

There's a moment every summer when the temperature hits 85 degrees and I look at my tap list and think, "every single one of these beers is too heavy for today." That's when I'm grateful for wheat beer. Light, hazy, effervescent, and absolutely perfect in the heat.

Wheat beers are also some of the most rewarding styles to brew because the yeast does most of the heavy lifting. In a Hefeweizen, for example, about 70% of the flavor comes from the yeast, not the grain. Pick the right yeast, manage fermentation temperature, and the beer practically makes itself.

What Makes Wheat Beer Different

The defining ingredient is, unsurprisingly, wheat malt. Most beers are made primarily with barley malt. Wheat beers use 30-70% wheat malt in the grain bill, which changes several things:

• Haze: Wheat proteins are different from barley proteins and create a persistent, attractive haze. This is a feature, not a flaw
• Head retention: The same proteins that cause haze create thick, creamy, long-lasting foam. Wheat beers have the best heads of any style
• Body: Wheat contributes a soft, bready, slightly creamy mouthfeel that's different from the crispness of all-barley beers
• Flavor: Wheat malt is milder and breadier than barley. It provides a blank canvas that lets yeast character and adjuncts shine

The Three Major Styles

German Hefeweizen

The most famous wheat beer in the world. Cloudy, banana, clove, effervescent, and endlessly refreshing. By German brewing law (Reinheitsgebot doesn't actually apply to wheat beers, which is ironic), traditional Hefeweizen uses at least 50% wheat malt. The banana (isoamyl acetate) and clove (4-vinyl guaiacol) flavors come entirely from the Hefeweizen yeast strain, not from any additions.

Belgian Witbier

The spiced wheat beer. Uses unmalted wheat, oats, and is flavored with coriander and orange peel. Lighter and more citrusy than Hefeweizen, with a slightly tart, refreshing character. Think Hoegaarden or Allagash White.

American Wheat

The clean-fermented version. American wheat uses a neutral ale yeast (or sometimes lager yeast), so you get the wheat character without the banana and clove. Often hopped with citrusy American varieties. Think the easy-drinking wheat beers at your local brewery.

Recipe: German Hefeweizen (5 gallons, all-grain)

Grain bill

• 5 lbs wheat malt (at least 50%, ideally 60-70%)
• 4 lbs Pilsner malt
• 0.5 lb rice hulls (prevents stuck sparges — wheat malt is huskless and gummy)

Hops

• 0.75 oz Hallertau Mittelfrueh at 60 minutes (10-15 IBU). Keep it low — hops should not compete with yeast character

Yeast

Wyeast 3068 (Weihenstephan) or WLP300. THE Hefeweizen yeast strain, originally from the Weihenstephan brewery. This yeast IS the beer. Don't substitute with US-05 or you'll just get a boring wheat beer.

Process notes

Single infusion mash at 152F for 60 minutes works fine. For maximum clove character, start with a ferulic acid rest at 113F for 15 minutes, then raise to 152F for the main conversion. Target OG: 1.044-1.052. The beer should finish between 1.010-1.014 for a light, refreshing body.

Carbonate to 3.0-3.5 volumes CO2. This is much higher than most ales (which are around 2.3-2.5 volumes). The high carbonation is essential for Hefeweizen's signature effervescence and contributes to the light, refreshing character.

Recipe: Belgian Witbier (5 gallons, all-grain)

Grain bill

• 5 lbs Pilsner malt
• 4 lbs flaked wheat (unmalted — traditional for the style)
• 0.5 lb flaked oats (adds silkiness)
• 0.5 lb rice hulls

Hops and spices

• 0.75 oz Saaz at 60 minutes (10-15 IBU)
• 0.75 oz crushed coriander seed at 5 minutes
• Zest of 1 sweet orange (Curaçao orange peel if available) at 5 minutes

Yeast

WLP400 (Belgian Wit) or Wyeast 3944. These produce a slightly fruity, spicy character that complements the coriander and orange. T-58 dry yeast is a reasonable budget alternative.

Recipe: American Wheat (5 gallons, all-grain)

Grain bill

• 5 lbs pale 2-row malt
• 4 lbs wheat malt
• 0.5 lb rice hulls

Hops

• 0.5 oz Amarillo at 60 minutes (15 IBU)
• 1 oz Citra at 5 minutes (aroma)
• Optional: 1 oz Citra dry hop for 3 days

Yeast

Safale US-05 or WLP001. Clean, neutral, lets the wheat and hops speak. This is the simplest of the three styles and makes an excellent session beer.

Wheat Beer Tips That Apply to All Styles

• Always use rice hulls. Wheat malt has no husk, which means your mash can turn into cement without some help. 0.5 lb of rice hulls per batch adds zero flavor and prevents stuck sparges
• Don't filter or fine. Haze is part of the style for all three traditions. Embrace it. If you cold crash and gelatin fine your Hefeweizen crystal clear, you've missed the point
• Serve fresh. Wheat beers are at their best within 4-6 weeks of packaging. They don't age well — the yeast character fades and the refreshing quality diminishes. Brew them, drink them, brew more
• Rouse the yeast before serving. For Hefeweizen especially, gently roll the bottle before pouring to resuspend the yeast. That yeasty haze IS the style
