hmm, well Williams lists it as intermediate, which I think means 2 stage fermentation.
Their description indicates that it's suitable for "room temperature" fermenting.
Our California Pilsner combines a rich hop character and aroma with the hearty flavor of warmer fermented California-style lager. The hopping schedule in this kit is designed to maximize the aroma and flavor of the hops over the usual clean bitterness. Ferment and age this kit at room temperature for a heartier flavor, or refrigerate for 4 weeks after bottling like a traditional lager for a smoother, more commercial character. Alcohol: 4.0%, IBUs 40. Includes 7 lbs. of our blended malt extract, Czech Saaz and other hops, liquid lager yeast, and corn sugar for carbonation. Makes 5 gallons with a starting gravity of at least 1.044. Ease of Brewing: Intermediate
While the instructions say
in one to three days at toom temperature (not below 60F ideally 60F-65F) Fermentation will begin...
NOW, don;t miss my point. I would NEVER second guess the members of this board and they're 100,000's of gallons of beer made.
but it is likely that this recipe is more designed to brew at room temperature
than it is an actual Pilsner.
but there's only one way to tell, and the proof is in the Primary.
here's to hoping we've all been mislead by the title "California Pilsner"
