White Labs trial fermentation data
« on: February 18, 2010, 07:46:13 AM »
Running my own yeast bank usually keeps me away from White Labs and Wyeast's web sites but I'm glad I just checked out White Labs.

They recently added data from standardized mini fermentation for some of their strains. This is pretty cool. However, they don't list the limit of attenuation of the wort that was used for the tests. I have to ask them about this.

I looked at them and was surprised by their diacetyl numbers. They have WLP 800 Pilsner yeast measuring 70 ppb diacetyl, and 830 German Pilsner yeast as producing 221 ppb diacetyl.
I thought it would be the other way around.
Any thoughts?

They are fermenting lagers at 55 F (~12 C) which is on the upper end of the accepted temp range. In addition to that they don't explain was "As is" and "Total diacetyl" is.

My experiences with White Labs have been helpful. They are willing to provide as much info. as they can. I've had phone conversations with their staff several times, some of which have been over a half hour each.

It took 1/2 an hour for them to convince you to read the tube where it says PITCHABLE IN 5 GALLONS OF WORT ;D
