Pacific Ale is an excellent yeast for West Coast IPA and Pale Ale styles. Leaves the beer a little sweeter and White Labs WLP001 California Ale.
Attenuation: 65-70%
Flocculation: High
Optimum Fermentation Temperature: 65-68°F

Alcohol Tolerance: Medium (5-10%)

Yeast Starter Required

These are live cultures. Although the White Labs tube says you can pitch this directly into your wort without a starter, this is not a good ideal for yeast that has shipped through the mail (unless you pay for ice packs and two day air or Priority Mail shipping). We sell these live cultures with the understanding that it is your responsibility to proof the culture on arrival by making a yeast starter. If you do not have yeast starter equipment, see this link for details on ours. Thank you and enjoy!


"Speed and attenuation not a problem"

By: Kris | Date: Nov 2, 2013 | Beer(s) Brewed: English IPA

I was intrigued by the flavor profile of this yeast, but have been scared away in the past by the descriptions of low attenuation and slow ferment times.

I'm happy to say I had no problems.

Pitched from a starter into 1.064 low mash temperature wort. Strong fermentation @65 blew foam for two days; primary completed two days after that. After racking @1.018 it continued to slowly bubble for the next 10 days @68 dropping an additional 2 points.

75% attenuation in about a week, seem reasonable to me. Good flocculation too.

Used in an English IPA it left a robust malt profile without crushing the hops (more hoppiness than Burton, which I have used many times before). Fruity esters are present without dominating.

"WLP041 Pacific Ale yeast"

I have made over a dozen batches of in your face IPA's with this strain. I made a 2 quart starter, as I do with all White Labs yeasts, and added it to three separate batches, 6 gallons each and have never had an issue. This yeast has not been slower or faster than the others I've tried. If you want to make a California IPA, use Simcoe, Citra and Cascade hops and this will be much more bold than one with the 001. If you want an over the top IPA, this is the best yeast available.

"Great malty IPA ... "

By: Tony V. | Date: Nov 20, 2012 | Beer(s) Brewed: IPA

Great yeast! A little slow to attenuate for me, but produced a great malty IPA with an intense fruity ester that went well with Amarillo hops. I'm glad it's a year round strain now! I want to try it in an English Bitter next time.
