Do you remember the "
Ulterior Motive" of my last brew day?
The last beer I brewed (
Ulterior Motive Amber Lager) was basically a big starter batch so that I could build up enough WLP833 German Bock Lager Yeast to brew a proper dopplebock.
The fact that I'll get a batch of beer to put in my keggerator is a bonus.
As you probably know, lagers generally require more yeast to get the fermentation job done.
Big lagers obviously require even more yeast, and a dopplebock is a great big beer.
I've used the technique of "yeast harvesting" from smaller lagers into bigger lagers before, and it ultimately ended up with my award-winning Maibock,
Helles in a Hand Bock-sket. It is less expensive than buying extra vials of yeast, and of course, I also end up with 5 gallons of a smaller beer to enjoy.
