CellarScience® CALI Dry Yeast | American Ale | Premium Beer 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 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. 

One sachet is enough to treat a 5–6 gallon batch. When calculating for larger batches, use at a rate of 2–3 grams per gallon of wort. We recommend rounding up by one full sachet rather than measuring out the yeast exactly.

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
Alcohol Tolerance: 10-11% ABV (WY1056 11%)
Attenuation: 75-84%
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 a full lineup of 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.

David Zorn on Feb 11, 2021
Dry yeast pack wasn't vacuum sealed, is it ok to use?
Todd Girouard on Feb 26, 2021
BEST ANSWER: Absolutely! I've used this yeast many times and have never had an issue. Really great stuff for my IPA's
Where do I find the attenuation for all of the CellarScience yeasts (as a percent, not "well" or "medium"? I don't find it on the data sheets.
john tingleff on Nov 21, 2022
BEST ANSWER: This yeast is a similar strain as Safale US05 from my experience.
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.
How many yeast cells are in a 12g packet of CALI dry yeast?
emery kujiraoka on Jul 23, 2020
BEST ANSWER: The 12 gram sachet contains 120 billion yeast cells.
Anyone ferment under pressure with this yeast? Curious how it did.
Philip Fischer on Mar 14, 2024
BEST ANSWER: I use it all the time, and it does great. I ferment under pressure using the fermzilla all rounder, and this yeast is my go to for ales. I start it using proper starter the day before, and it really takes off. About one week from grain to glass.
what is the shelf life of this yeast ?
Chris Herzog on Jan 25, 2023
BEST ANSWER: Not sure what the manufactures recommendation is but I’ve had success with this yeast that was outdated and non refrigerated. Obviously not recommended but I went for it anyways. Good luck
what is the alcohol tolerant of this yeast?
Ryan Nelson on Jul 27, 2020
BEST ANSWER: Brewed up to 11% with it.
I brewed a 10 gallon Chux 3-16 and SG was 1.068. I hydrated the Cali with Go Ferm protect and distilled water. Temps were 69. PH is 5.3. NO activity 3-16. I agitated by stirring. What are my options? I have never had no fermentation at this point in the process. Dead yeast?
Paul Gilbert on Mar 16, 2022
BEST ANSWER: You should not use distilled water to rehydrate or make a starter, use regular tap water (boiled) or bottled water, I know it has been a while since you asked this question but the best thing to do when no fermentation is going on is to repitch yeast, cheers.
What is the expected attenuation with this yeast?
Jukka Saario on Nov 11, 2021
BEST ANSWER: What I like abut it, it's fast. Last time I used it: 1.063 @ 88°- 1.012 @75° in 3 days.
I am making a Goose Island Bourbon County Stout clone and will have an OG of around 1.140, I need to make sure this yeast will attenuate well with overpitching.

How big of a beer has this stuff fermented without stalling?

very active yeast
I would recommend using a blow-by or a 6-gallon carboy for fermenting. Yeast acts like a #4 yeast product. The " English version" acts like the standard #5 yeast. Great price @3.99.

Out preformed the competition that cost twice as much. Cellar science brand is my new yeast.
Worked very well . Especially being half the price compared to white labs liquid . I definitely will be using this brand from now on. Wish I used it sooner would have saved a ton of money.
