Step 5: The Boil
Now bring the contents of the brew pot to a boil. Then, remove from heat and stir in the malt extract. Return to heat and again bring to a boil. Be careful here! This is the point where you are at most risk of boiling over. A boil over is something you definitely want to avoid as you'll have quite a sticky mess to clean up if it happens. Once you have a controlled boil add about 2/3 oz of the hop pellets to the boil and maintain the boil for 60 minutes to get the most from the bittering potential of your hops. Submerse your kitchen strainer in the boil for the last 15 minutes to sanitize it for later use. At the end of 60 minutes turn off the heat and add the remainder of the hop pellets. Cover and let the newly added hops steep for 10 minutes. Hops added at this point will contribute some hop flavor and aroma to your finished beer.
