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 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 California, WY1056 American, US-05 American Yeast

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.

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!

Great Start
Pitched the yeast into some malt I boiled and cooled for a yeast starter. Still going strong after about 18hrs when I pitched into the wort. Fermenting actively now on next day. Nice full 12g packet. We'll see in a few weeks about the taste. My first time trying this yeast.

CALI Dry Yeast
I’ve used dry and liquid yeast in the past six years of brewing all grain beers at home. This is the first time I used CALI dry yeast I was very happy with the results. I pitched the yeast late afternoon and had in active fermentation by early the next morning at about 65°. One packet Ezell he handles 5 gallons of wort.

Good West Coast Ale Yeast
In comparison to US-05 and WLP001: Started quickly. Good neutral taste. American wheat I brewed turned out great.

Easy product to use.
This yeast was fast acting and pretty aggressive at the start.

For American Ales
This yeast is very active and ferments completely and quickly.` It fermented not only all of my barley malt, but also most of the specialty malts. I recommend this yeast for cream ales and other light colored ales, but not for any ales that utilize specialty malts. I will not use this in the future because it does not work well with my recipe. It is a good yeast for those wishing to produce an American style beer or cream ale. It works well either with rehydration or sprinkled dry onto the wort.
