White Labs | WLP400 Belgian Wit Ale Yeast | PurePitch® Next Generation

Brew authentic Belgian witbiers with White Labs WLP400 Belgian Wit Ale Yeast | PurePitch® Next Generation, the classic liquid yeast strain renowned for producing the signature herbal, spicy, and lightly fruity character found in traditional Belgian white ales. Each 70 mL PurePitch® Next Generation pouch contains approximately 150 billion cells, providing enough healthy yeast for a standard 5-gallon batch without requiring a starter for most moderate-gravity beers. WLP400 is the ideal choice for Witbier, while also performing exceptionally well in Belgian Pale Ale, Saison, Belgian Tripel, and even Cider where phenolic complexity is desired.

WLP400 produces high phenol expression with notes of clove, herbs, and spice balanced by light fruit esters, creating the unmistakable aroma and flavor profile associated with classic Belgian witbier. Its naturally low to medium flocculation helps maintain the traditional hazy appearance of the style while delivering a dry, refreshing finish that complements ingredients like coriander and orange peel.

This liquid ale yeast features low to medium flocculation, 74–78% attenuation, STA1 negative status, and 5–10% alcohol tolerance. It performs best between 67–74°F (19–23°C) and is packaged in White Labs' PurePitch® Next Generation pouch with approximately 150 billion cells for consistent fermentation performance and reliable pitching rates.

For best results, store refrigerated between 33–38°F and do not freeze. Pitch cold into well-oxygenated wort and ferment within the recommended temperature range. One pouch is suitable for most standard 5-gallon batches, while a yeast starter is recommended for higher-gravity beers or older yeast to maximize cell health and fermentation performance.
