My second “summer ready” light lager after making an International Pale Lager. A fellow North Carolinian, Derrick Flippin, won at NHC last year with his American Lager so I figured why not start with his recipe and modify it for my system.

6/23/17 pulled half pint and still a bit dusty so added gelatin. tastes good. maybe a little diacetyl? hard to tell if its that or all that corn 🙂
this beer turned out really well. i had a very had time telling it apart from PBR. i preferred the international pale since it was a bit more flavor neutral (less corn) but both really good pool beers. the danish lager yeast turned out really well although it was a bit more work that german lager (wlp830) which dropped crystal clear much sooner than danish lager.
