Brewing beer is the process of combining a starch source (in this case, a malt brewing 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. Remove the yeast packet (not needed for this recipe) from under the lid of the can of Brewing Extract, then place the unopened can and LME in hot tap water.
    2. Using the measuring cup, pour 4 cups of water into your clean 3-quart or larger pot, then bring water to a boil, then remove from heat.
    3. Open the Brewing Extract and the LME, and pour the contents into the hot mixture. Stir until thoroughly mixed. This mixture of unfermented beer is called wort.
    4. Fill keg with cold tap water to the 4-quart mark on the back.
    5. 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.
    6. Sprinkle ONLY the Safale US-05 yeast packet into the keg, and screw on the lid. Do not stir.
    7. Put your keg in a location with a consistent temperature between 59° and 75° F (15°-24° C), ideally about 65°F and out of direct sunlight. Ferment for 21 days.
    8. After 1 week of fermentation, add the watermelon juice and let ferment for 2 more weeks.
  • Prepping the Watermelon Juice:
  • Set a fine-mesh strainer over a bowl; set aside.
  • Place the watermelon in a blender and blend until liquefied, about 1 minute.
  • Pour through the strainer into the bowl and scrape a rubber spatula against the inside surface of the strainer to push the juice through until only pulp remains.
  • Discard the pulp (You should have about 2-3 cups of juice).
  • After approximately 24 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 to be dormant. Your beer is still fermenting. The yeast is still at work slowly finishing the fermentation process.
