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
