Notes
Ferment at 61F 4-5 days. Cool to 32 over 5 days. Lager at 32 for 21 days.
Took 3-4 weeks to fully carbonate at room temp.
Edited recipe on 7/19/12 to go to .5 lb Vienna malt from 1.25 lb.
9/11/2013: Last couple of batches came out very slightly high in OG (1.050-1.053). Changing recipe today to show expected efficiency of 80%, and lowered pils malt and wheat malt to 7.5lb and 0.75lb respectively.
Also, consider using different hops - German noble hops as stated in BJCP 6C.
4/30: Used 8# Pils, 1# Wheat Malt, .5# Vienna. Got 5.5g @ 1.052.
7/16/2016: Got very high efficiency, so I scaled the hops up in recipe to get 6.25 gal to fermenter. Note that my earlier IBU target had been 26. This batch will be 29. After brewing, efficiency was not so high, but still 80%. IBU will be 32. Back off on hps next time.
1/21/2017: Modified recipe to target 24.6 IBU.
