Fröhlich Bock and unruly lager yeast

Fröhlich Bock - translates to Happy Billy Goat...

This is a style I happen to really like. There is plenty of flavour and complex Maltiness (not a real word). My absolute favourite are the smoked versions, RauchBier (commercial examples can be purchased locally at the West Richland Beer and Wine Store). I have added smoked malt to this one, but only to add a little character.  12oz of smoked malt in a large beer such as this one is not enough to pick it out. This beer is probably one of my absolute favourites.











12/26/2011 - the gravity came down from 1.072 to 1.014 with an ABV of 7.5%. It has been racked into a secondary and is now lagering. I plan to keg and apply pressure the weekend of January 14th or 21st. The samples I have tasted seem to have a little of the rauchmalt coming through and it appears to be relatively balanced. I'm excited about this one.

1/22/2012 - Put this one into a keg and on the gas. Tastes fine, seems slightly sweet at first, but then finishes dry. 2lbs of smoked malt next time.

Mash Notes: Used for some authentic German styles. Attempt to draw decoction from the thickest portion of the mash. Profiles vary. Some traditional German mashes use a long acid rest at 40 deg C. Also some sources recommend the decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it.
