Brewing beer is the process of combining a starch source (in this case malt extract) with yeast. Once combined, the yeast eats the sugars in the malt, producing alcohol and carbon dioxide (CO2). This process is called fermentation.

  1. If applicable, remove the yeast packet from under the lid of the can of hopped malt extract (HME), then place the unopened can and unopened liquid malt extract (LME) softpack in hot tap water.a
  2. Using the measuring cup, pour 4 cups of water into your clean 3-quart or larger pot. Bring water to a boil, and then remove from heat. Open the HME and the LME,b pour the contents into the hot water. Stir until thoroughly mixed. This mixture of unfermented beer is called wort.
  3. Fill keg with cold tap water to the 4-quart mark on the back.c
  4. Pour the wort into the keg, and then bring the volume of the keg to the 8.5-quart mark by adding more cold water. Stir vigorously with the spoon or whisk. d
  5. Sprinkle the yeast packet into the keg, and screw on the lid. Do not stir.
  6. Put your keg in a location with a consistent temperature between 68°and 75°F (20°-24° C) and out of direct sunlight.e Ferment for 14 days.f

After approximately 72 hours, you will be able to see the fermentation process happening by shining a flashlight into the keg. You'll see the yeast in action in the wort. The liquid will be opaque and milky, you will see bubbles rising in the liquid, and there will be bubbles on the surface.

Your fermentation will usually reach its peak in 2 to 5 days (this is also known as “high krausen”). You may see a layer of foam on top of the wort, and sediment will accumulate at the bottom of the fermenter. This is totally normal. Complete fermentation will take approximately 2 weeks.

After high krausen the foam and activity will subside and your batch will appear dormant. Your beer is still fermenting. The yeast is still at work slowly finishing the fermentation process.

  1. Hot water will help the syrup-like malt inside the can and softpack pour more easily.
  2. The can is more easily opened from the bottom.
  3. Between 40° and 60°F. Tap water, bottled spring water or charcoal-filtered tap water all work great. Most sources of water (even hard water) work just fine, but be sure not to use highly chlorinated water or water with high levels of iron in it. These can produce off-flavors.
  4. Stirring will introduce oxygen to the wort that gives the yeast what it will need to begin fermenting.
  5. It is extremely important that you maintain a steady temperature between 68°and 76°F. Too old-the yeast will go dormant. Too warm-the yeast will produce off-flavors.
  6. Be sure to place in a safe place that is free of important items that should not get wet. Don't forget beer is a liquid.
