Brewing in Southern California
This yeast works very well at the temperatures in Southern Ca. No off flavor when fermented in the low 70's.

Delicious and refreshing taste
The California Lager yeast makes an excellent tasting "California style" beer. I have found it to be a slow starter both times I have used it, but it always results in a very refreshing beer that's true to the style and great during the heat of the summer.

M54 Yeast
I just tapped a keg of  Pilsner using the M54 Yeast by Mangrove Jack and I must say it turned out better than expected. This is their new yeast strain that can be fermented at higher temperatures.  Considering I kept it simple with a single mash step and did not hassle with the normal details of lagering, this came out very good.  I just fermented it in the closet at 69 degrees F for 3 weeks, carbonated in a keg for one week and tapped it.  For all of the saved time and effort I don't know if I would go back to the old way.  For a homebrewer this affords the ability to make a nice Pilsner without all of the work of maintaining colder fermintation temperatures.
