Very nice to hear. I noticed you only pitched a vial of yeast without a starter. Sounds like the brew is ok and your OG wasn't too high to begin with, but in the future I would recommend a starter...I'd hate to put all that effort into AG brewing and then not pitch enough yeast and get a stuck fermentation or off flavors or anything else undesirable.
Also regarding the hop flavor, an oz of Cascade at 60 min and then another at 30 min is definitely going to give you some strong hoppiness. It will probably mellow out somewhat, but will stay a bit bitter.
Anyways, just my opinions.
I noticed you said you filtered, are you talking about the yeast? If so, I'm curious to how you did that?
Cheers!
