title_body: What does "all malt" mean?
upvoted_answer: All malt beer is made entirely from mashed barley malt and without the addition of adjuncts, sugars or additional fermentables.
  
  From an expert of a widely known brand beer producer in my country (Turkey), beers here must be at least 60% malt (This may be different in other countries). The rest are adjuncts, like sugar or corn or rice etc. Using adjuncts is also for decreasing the cost or to lighten the color of beer.
