CellarScience® CALI Dry Yeast

CellarScience® CALI Dry Yeast

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

The classic American ale strain. Famous for its clean, neutral flavor and its ability to be used in any style. Emphasizes malt and hops. Attenuates well. CALI is eligible for direct pitch straight into your wort. 

Every batch is PCR tested to ensure quality. 

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

How do you tell from the code on the packet what the born date is of this yeast?
David Zorn on Feb 11, 2021
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!
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
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.
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?

Unsuccessful fermentation 2/3 batches.
I've brewed at least 3 batches with the cali dry yeast that was saved in the fridge as backup for liquid yeast. The last 2 batches were under 1.065 and the wort was oxygenated well and pitching temps were in range. Even with hydration, fermentation would not start after 2 days including some wort agitation and warmed up wort to 75 degrees. The last batch
I pitched directly and oxygenated the wort even more and no bubbles after 2 days. Had to repitch both batches and am left a bit confused.

Works like a charm. High attenuation, clean fermentation, decent flocculation makes it a predictable and reliable yeast for most ales.

Cali Dry yeast
Sprinkled on top of one batch , hydrated and added to another batch. Good fermentation in both batches, though a little more delay unhydrated.

Great Yeast. Great Value.
I fermented a Cream Ale with Cali Ale yeast and it turned out perfect. Strong, healthy fermentation. Short lag phase compared to other dry yeasts I've tried. Did not rehydrate. I use yeast nutrient and oxygenate with O2 (even with dry yeast, although for only 15 seconds instead of 1 minute). The beer turned out great! Would absolutely recommend for any recipe where a neutral ale yeast is desired. Squeaky clean at 62F with a diacetyl rest at 70F for 48 hours.

Cellar Science Cali dry yeast. Excellent yeast, will be using it in the future!
I got my first package of Cellar Science Cali dry yeast from a friend who didn’t know to keep it refrigerated and it was stored at about 80 degrees for over six months. I used it in a batch of American Pale Ale. It had a longer lag time than usual. But fermented well with a 5.5 ABV. Final gravity 1.010. After 8 days. Since then I have had excellent results with this yeast. I will be using it in the future!

A Great Value Yeast
I've used this a couple of times and had no problems at all. I will be getting some more next order I make as it will works with most of the beer I brew. Bottom line is that is a solid performing yeast at a great price.
