Beer Smith has several styles to choose from in it Style.bsm

BJCP 2004
BJcp 2008
Your can get to the styles for your recipe through Tools>Options
The default for a New Recipe is Altbier 5D -- Which is FAD0L 2007 which does not follow the BJCP guide lines. If brewing an Altbier make sure to Choose Northern German Altbier or Dusseldorf Altbier.
Of course, me being the lazy person that I am would choose the default and wonders what is wrong
