CellarScience™ CALI Dry Yeast

Please select from the following option(s) to see pricing and availability.

The classic American ale strain that has a long history of producing amazing beers. Famous for its clean, neutral flavor and its ability to be used in any nearly any style. The reason this is the most popular strain in homebrewing and craft brewing is that it allows malt and hops to shine. You can never go wrong with CALI.  Like all CellarScience yeast, CALI is eligible for direct pitch straight into your wort. CellarScience provides 12g of yeast per sachet, which is up to 9% more than any other brand of dry yeast. Every batch of yeast is PCR tested to ensure quality. CALI has been selling to pro breweries for awhile but was just recently packaged down to sachets for homebrewers. 

Use at a rate of 12 grams per 5-6 gallons of wort.

Direct Pitch OR Rehydrate:
CALI yeast can be direct pitched with great results by sprinkling it onto the surface of the wort in your fermenter. However, proper hydration helps ensure a healthy fermentation and is especially recommended for beer with a starting gravity above 15°P (1.061 SG). To hydrate yeast, first sanitize the yeast pack and a pair of scissors. Boil tap water to sterilize and then cool to 85-95°F (29-35°C). Use 10 grams (0.35 oz) of water per gram of yeast. Sprinkle the yeast onto the water, allow the slurry to stand undisturbed for 20 minutes, and then swirl. Use small amounts of wort to adjust the temperature of the slurry to within 10°F (6°C) of the wort temp before pitching. Ferment between 59-72°F (15-22°C).

Optimum Fermentation Temp: 59-72°F
Flocculation: Medium
Similar Strains: WLP001, WY1056, US-05

CellarScience Yeast:
For years liquid yeast has been sold as the higher quality option but times are changing. Yes, 20 years ago dry yeast was made by bread yeast producers and the quality was not as good as liquid yeast. CellarScience is helping to flip that script with the release of five high quality dry yeasts. Cell count and viability is usually higher than commercial liquid yeast pitches, which vary from pouch to pouch and don't ship well. CellarScience yeast can be pitched directly in most batches of wort, offering significant time savings. Yeast that is quick and easy to use, high quality, and available at a reasonable cost adds up to a tremendous value. Quality yeast that doesn't "break the brink".

CellarScience Nutrients:
For high gravity ferments consider rehydrating yeast with CellarScience FermStart yeast hydration nutrient. For high gravity or low nutrient wort, feed your fermentation with CellarScience FermFed DAP Free complex yeast nutrient mix.

Stephen H on May 1, 2020
It iits 1g more yeast and a lower price. Figured I would give it a try
Scott J on Apr 30, 2020
They were out of us05 and bry97. This was actually a better sub for the us05. I'm fact, it's could be the same - believe this is distributed by brewmaster wholesale who just repack stuff into smaller UOMs from other companies. I'm stoked!!!

Cali looking good
So far so good. 2 days in primary and all is well. Too early to tell but I like what I see!
Day 2 and Cali is pretty happy.  Rehydrated in 1/2 cup of sterile water and pitched.

Cali yeast is wonderful
This Cali yeast is a beast. It is now one of my go to dry yeasts. It is similar to WLP001 or US-05. I always have a extra pack in the fridge as if I ever have a stuck fermentation, I can count on my dry yeast to fix the issue. Rehydration of the yeast is important and a simple task to ensure success
