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. 

Dosage:
One sachet is enough to treat a single 19-23L batch. When calculating for larger batches, use at a rate of 0.5-0.8g per Liter. We recommend rounding up by one full sachet rather than measuring out the yeast exactly.
[51.28-85.47g per 100L]

Direct Pitch or Rehydrate:
CALI yeast is designed to be sprinkled directly onto the surface of your wort with no oxygenation required in the initial fermentation. Our aerobic growth process makes this possible by creating dry yeast with high viability and high sterol levels. CALI yeast is pre-loaded with essential nutrients to ensure a successful, complete fermentation. While not required, some brewers prefer to rehydrate yeast. To hydrate yeast, first, sanitize the yeast brick and scissors. Use 10 grams of sterilized tap water between 29-35°C mixed with 0.25 grams of FermStart (Yeast Nutrient) per gram of yeast. Sprinkle yeast on the water. Allow the slurry to stand undisturbed for 20 minutes, then swirl. Use small amounts of wort to adjust to within 10°F (6°C) of wort temperature before pitching. Ferment between 15-22°C.

Flocculation: Medium
Alcohol Tolerance: 10-11% ABV (WY1056 11%)

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 bank".

Wish I could love it

"I really want to love it BUT, I get inconsistent results with Cellar Science yeasts. Quite annoying when fermentation stops before it should. I'll still play around with it, but when I'm looking for a definite result, I'm afraid this won't be it."

Andries E. (3/5)

Neutral

"Good alternative to US-05"

Joel W. (5/5)

Magnificent

"The workhorse for Pale Ales. A great chico yeast strain that is dependable and gives a clean flavour. I buy heaps of it and the Hazy IPA yeast made by CellerScience. Never had a bad batch. The krausen it makes in 24 hours from the start of fermentation is soft and pillowy. Great yeast at the right price!"

FrankG (5/5)

Great for IPAs

"Love this yeast for my IPAs"

Hamish D. (3/5)

Slower ferment, still good

"Bit of a slow ferment compared to US-05, but the flavour profile is still neutral. Ferments slightly dryer than US-05 (1,08 on a recent IPA I brewed Vs 1. 011 on US-05)."

Shane B. (4/5)

US05 equivalent

"Cheaper and it’s very fresh!"

J A. (5/5)

Got there eventually

"Eventually fermented out OK. But quite slow to start +48 hours even though pitching at the correct rate. US-05 did the same job in half the time."
