[[Boiling]] your [[wort]] performs several important functions. It sterilizes your wort, vaporizes many undesirable compounds, releases bittering oils resins from the hops and coagulates proteins and tannins from the grains so they can fall out during cooling. To achieve all of these noble goals you need to boil for at least 60 minutes, and for lighter styles of beers a longer boil of 90 minutes is desirable.
