title_body: Can I get rid of this wood fiber taste?
upvoted_answer: I would suggest buying any other kind of non-flavored coffee (or borrowing some) and using your same parameters to make a pot.  That should determine whether your machine/process is imparting that taste to the beans or if it's just the coffee itself.  
  
  Lightly roasted coffee often has tastes described as woody, grassy, or sometimes tea like.  This can vary from very noticeable at light roast levels to not at all noticeable at moderate levels.  Even if you have purchased those same beans before and were not expecting the taste, it's possible you purchased a bag less roasted than previous bags you have bought.
