CellarScience® JUNGLE Dry Yeast | 15 grams

CellarScience® JUNGLE Dry Yeast is a 15 g dry ale yeast sachet built for expressive, hop-forward beer. It produces strong tropical ester character, especially guava, passion fruit, and mango, and is designed to work well with fruity hop varieties and generous dry-hop additions.

Use JUNGLE when you want fermentation character to help push the fruit side of an IPA, hazy pale ale, juicy IPA, tropical ale, or experimental hop-forward beer. It is not a neutral American ale yeast. This strain is meant to be expressive, fast, and forgiving across a wide fermentation range.

What JUNGLE is best for

• Hazy IPA, New England IPA, juicy IPA, and DDH pale ale
• Modern hop-forward beers where guava, mango, and passion fruit notes are welcome
• Warm or variable fermentations where broad temperature tolerance matters
• Pressure fermentation up to 12 PSI when your process supports it
• Higher-gravity ales where a robust yeast is useful

Fermentation profile

JUNGLE specializes in fruity ester production and hop biotransformation. Paired with fruit-forward hops, it can help intensify tropical aroma and make dry-hopped beers feel more saturated and expressive. For a cleaner American ale profile, use a yeast such as CellarScience® CALI or SafAle US-05 instead.

How to use JUNGLE dry yeast

One 15 g sachet is intended for a typical 5-6 gallon batch. Sprinkle the yeast directly onto cooled wort. For larger batches, use 2-3 grams per gallon of wort and round up to the next full sachet instead of trying to split a tiny amount exactly.

For the best expression, pair JUNGLE with hops that already lean tropical or fruit-forward. Keep oxygen exposure low after fermentation begins, especially for dry-hopped beers.

Storage

Store sealed dry yeast in a cool, dry place. Refrigeration is recommended for best long-term viability and shelf life.
