Planning on bottling my version tonight. In no way would I mistake it for a true Stella, but it's still going to be good. The sample I've had has quite a hop pop, not at all like the smoothness of Stella. I think maybe the Liberty hops went into the boil too late. Next time I'd go with a 60 minute addition of Saaz, and then maybe a 30 minute addition of Liberty or Saaz.
Another contributor could be my water. It's fairly hard and probably need to use 75-80% distilled/RO water. This could be the issue with the hops popping more than expected. Regardless, I'll likely be brewing this again someday, or at least another version of it!
My first lager!
