Ice Packs / Shipping:For best results, we strongly recommend adding an ice pack to your liquid yeast order. Ice packs do not guarantee that yeast will arrive cold, but will keep yeast colder for longer during transit. We can not replace yeast that arrives warm. In warm weather months, we highly encourage choosing dry yeast. Liquid yeast is final sale. As a live, perishable ingredient that requires refrigeration, we are unable to accept returns or exchanges once an order has left our warehouse.

Storage: Store in the fridge (33–38ºF). Do not freeze. Pitch cold - do not warm to room temp prior to pitching. Use within 4 months for direct pitching. For pouches older than 4 months, or that are warm, use a yeast starter to boost cell count.

Fermentation Temp Range
Each yeast strain has a temperature range where it performs best. Lagers require cooler temps, while Kveik yeasts can ferment in extreme heat. Maintaining the proper fermentation temperature for each yeast strain is crucial its health. Matching a yeast's ideal range to your environment (or your ability to control temp) is key to getting clean, consistent results.
Scale from 30°-120°F

Frequently Asked Questions

WLP400 produces high phenolics (herbal, spicy, clove-like notes) with a lightly fruity ester profile. The result is the classic aromatic complexity of Belgian witbiers.

WLP400 has low to medium flocculation, meaning the yeast stays partially suspended in the beer. This is normal and traditional for the Witbier style — the haze is part of what makes it a white ale.

Each 70 mL PurePitch Next Generation pouch contains approximately 150 billion yeast cells, suitable for most standard 5-gallon batches.

Ferment between 67–74°F (19–23°C). The lower end of the range produces a more restrained, balanced profile; the upper end increases ester and phenol expression.

For standard gravity 5-gallon batches a starter is generally not required. For higher gravity beers (above 1.060 OG) or lagers, a starter is recommended to ensure healthy fermentation.
