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
Cell Count: 10 billion cells per gram
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.

How many weeks in fermenter? 2 or 3? I used Cali Dry Yeast and have been fermenting at 67 degrees. Fermentation took off and was vigorous and seemed to finish after 3-4 days. OG was 1.062. Coming up on 2 weeks this weekend. I am wondering if I should raise the temp a bit or let it sit for longer. Thanks!

BEST ANSWER: This yeast usually finishes up a beer of this gravity in 10 days. A 4 day fermentation is fast but not worrying at 67 degrees. If the foam is gone and the yeast are sinking then they are done fermenting and you can start dry hopping. (Some belgian yeast strains truly limp over the finish line for 2-4 weeks.) Go ahead and take a sample and see how the beer tastes. We are looking for any buttery flavor or slick mouthfeel, and a stable final gravity. The Butter flavor is the last thing the yeast clean up before stopping fermentation and raising the temperature is a good way to help them finish this step. If the gravity is the same, say, on Thursday as it was Monday then you are 100% good to package, dry hop, or barrel that beer. Cheers!
Try to keep room temp at 69-72 but in Florida room can get to 74. Wort probably gets to 74-76. Anyone brewed warmer than 72?
Nick Horsky on Jul 26, 2020
BEST ANSWER: Yes, I have. My last fermentation was around 76-78, I haven’t noticed any issues.
what is the alcohol tolerant of this yeast?
Ryan Nelson on Jul 27, 2020
BEST ANSWER: Not seeing any specific info on that but S-05 which this yeast would most closely be related to has a tolerance of 9-11%.
How many yeast cells are in a 12g packet of CALI dry yeast?

good yeast
This yeast fired right up in a brew of Hop Gatherer. Cast at about 78 degrees and was bubbling about 4 hours later at 65 degrees ambient temp. Fermenting in my detached garage where current temps are running between 55 and 70. Still bubbling slowly a week later.

Will get more
After attempting to use another yeast that didn't work, made a quick switch to CellarScience. It worked great - super easy, pay attention to the instructions. Worked just as directed. Within 20 minutes the yeast was active and did a great job in the fermenter. Love it!

My go to for IPA
I used it for a hazy ipa. Got it going in a starter for 24 hours prior to pitching. Went to work about 6 hours later. Great job and good tropical flavors. Made another with s05. Everyone preferred the Cali.

90% attenuation. Can't complain about that
Used with the Haze Craze IPA. There wasn't a recommended dry yeast, but this did the job very well. PItched at 80F and still went right to work and hit 90% attenuation within a week.

Good stuff
Did a double batch of California common.
Cali in one, Mangrove jack M-54 in the other.
Both were good, Cali was best.
M-54 took forever to settle out.
Will be doing a Cali US-05 compare next.
Cali price is nice too.

Fermentation is overly vigorous
I have used this yeast for two five gallon batches during the time that my standby Safale US-05 was out of stock. Both times the fermentation was overly vigorous and produced lots of foam which stopped up my air lock and caused it to blow out from my fermenter. I never experienced this problem with US-05 after brewing over 50 batches with it. I will return to US-05.

Used in a high SPG DIPA. Fermentation took off quickly and was vigorous. Complete to 1.006 SPG in a week. Sat on the trub for another week before a couple weeks in the corny keg. Pouring delicious beer now and still improving.

Pitched dry into batch of blonde ale. Active fermentation within 8 hours. Yeast settled nicely with noticeable chunks in cake, not easily disturbed. No off flavors in beer, but there are some citrus / lemon hints to flavor.
