DRAFT – FOBs

A regular beer line cleaning program must include venting the FOBs with the line cleaning solution.  If you see that you have growth inside of your FOBs (shown) then your line cleaners are not cleaning your draught lines properly. Unfortunately, we see this far too often.

The sand-like grains inside of this FOB is beer stone and yeast which creates “diacetyl”.  This gives the beer a buttery taste.
