White Labs American Lager Yeast

By: Gary | Date: Dec., 4th 2013 | Beer(s) Brewed: Golden american lager

This yeast makes one incredibly smooth and clear lager. I used this yeast on a gold lager made with pils and vienna malts. It was hopped moderately with Kent Golding hops and was amazing. I would have put this lager up against any lager out there! It would make a wonderful house tap beer that everybody would enjoy. It ferments very well at 55f and is fast. I used one vile of the yeast with a one pint starter then a 48 hour rest after fermentation was complete

WLP840 American Lager Yeast is a great lager yeast!

By: T. Enix | Date: Jun., 10th 2013 | Beer(s) Brewed: Pre-Prohibition Lager

For my very first batch of beer, I used WLP840 to ferment a Pre-Prohibition Lager. It turned out great! I've had many compliments and requests for more of the Pre-Pro Lager. I attribute much of my success with that beer to the yeast. The flavor profile of the yeast certainly gave my beer a premium lager taste.
