  • 100 billion cells per pack, treats up to 5 gallons
Ice pack:

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

Wyeast 3944 produces a flavor profile dominated by spicy phenolics with restrained ester production. The result is a clean, clove-forward character that complements rather than competes with the citrus, spice, and wheat elements of a traditional witbier.

It ferments fairly dry with a slightly tart finish — a defining characteristic of the style that works especially well with the oats and wheat in a classic witbier grain bill. With medium flocculation and 72–76% attenuation, this strain leaves the beer crisp and refreshing while maintaining enough body for the style.

Wyeast 3944 performs best between 62–75°F. Fermentations at the lower end of the range emphasize the clean, spicy phenolic character, while slightly warmer temperatures can bring out a touch more ester complexity.

Wyeast 3944 is well-suited for witbier and a variety of Belgian-style ales.
Ideal for:
• Belgian Witbier
• Belgian IPA
• Specialty Ale: White IPA
• Belgian Dubbel
• Belgian Tripel
• Spice, Herb, or Vegetable Beer

Liquid yeast can deliver excellent fermentation performance and a wider range of strain options, but it’s a living, perishable product that requires a little extra care.

  • Liquid yeast may arrive warm. Ice packs help reduce heat exposure but do not guarantee cold arrival.
  • Refrigerate it when received and plan to brew as soon as possible.
  • We recommend adding an insulated mailer + ice pack to liquid yeast orders.
  • During May–September, dry yeast is strongly recommended due to higher shipping temperatures.
  • Liquid yeast is final sale and cannot be replaced due to heat exposure during transit.

Frequently Asked Questions

Wyeast 3944 produces a flavor profile dominated by spicy phenolics with low to moderate ester production. Expect a delicate clove and pepper character with a slightly tart, dry finish — a clean canvas that lets your spice bill shine.

Yes. Wyeast 3944 is specifically designed for Belgian witbier. Its spicy phenolic character, dry finish, and slight tartness are exactly what the style calls for — especially when paired with orange peel, coriander, and oats.

Top-cropping means this yeast rises to the surface of the wort during fermentation rather than staying suspended or settling to the bottom. It ferments vigorously and produces a large krausen, so you need to leave at least 33% headspace in your fermenter to avoid overflow.

Wyeast 3944 ferments best between 62–75°F (17–24°C). Lower temperatures in this range emphasize the clean, spicy phenolic character. Higher temperatures can increase ester production and add more fruit complexity.

A yeast starter is recommended for high gravity beers or if the pack is past its best-by date. For standard gravity witbier (under 1.060), one pack of Wyeast 3944 is sufficient for up to 5 gallons without a starter.

Yes. Wyeast 3944 is a liquid yeast and must be stored refrigerated at 33–38°F. Do not freeze. We recommend adding an ice pack to your order during warmer months to protect viability during shipping.
