Isn't lagering more of a process? So technically you can 'lager' with any yeast. That being said, I agree with the comment of Top vs Bottom fermenting being the distinction

Perhaps it is the specific crop. The crops change year to year. However, I've heard people voice that they don't use Citra and prefer the other 'C' hops. Other than that, the other posts make good points about water pH, etc.
