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

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.

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: Brewed up to 11% with it.

Switched from liquid yeast and love it!
I’ve always used liquid yeast since I had the impression it was better. But I gave Cali dry yeast a shot and it did amazing! I hydrated one 12g packet 30 min before pitching into 5 gallons of 1.053 Pale Ale. It was active in about 12 hours and stayed active for 4 days, with final gravity ending at 1.006. Very happy with the results!

Used this yeast for the first time on a red ipa amd was very pleased with results. The price of the product was very reasonable. I will use it again.

I was really excited to try this yeast out. I went with a Sierra Nevada clone for it’s clean flavors as I wanted to see what this yeast can do. It doesn’t “go off” but gets going pretty fast. It leaves a lot of malty flavor behind which, if that’s what you want, is good. I was hoping for a cleaner, crisper yeast. I’ll probably go back to my go-to dry yeast Nottingham but keep this one in mind for some winter ales.

Good Cal Ale Yeast
I made a couple complex malty, hoppy extract IPAs with this yeast and both turned out great. Good attenuation and quick fermentation when properly hydrated and the wort was aerated very, very well. I didn't use a starter with this. My OG of 1.064 with one packet worked well. FG was 1.012. Flavor and aroma is what I would expect from Cal Ale yeast so due to the price it is a great value and therefore 5 stars.

Fast, clean character, consistent!
I've now done 8 brews with CALI. Delicious, clean character, and fast fermenting! I have 4 more brews in the queue with these delicious beasts!

Just buy it
Pitched directly into 1.054 wort, attenuated to 1.010, beer tastes snappy and clean. $3.50?! This is now my new go-to

Great yeast at a great price
Pitched dry on top of wort at 70 F, started in about 12 hours, has smelled very clean so far 4 days into fermentation at 65 F. No esters that I can detect over the hop scent.

Excellent and powerful starter.
Have used dry yeast for the past 30 years, Fermentis was used exclusively in my brewery as well. This is a fine yeast and works itself up quickly and vigorously. Here it is in a Copperhead after just 6 hours. I rehydrated with room temp RO and it went right to work. I had bubbling on just an hour.
Will give taste results but have zero worry it won't be great.
Smells of fresh bread when opening the package.
Up and running
Pushing the envelope
Oofa na Tony, this yeast is oogatz!
