Malt Extracts


Yeast Options



  1. If you chose liquid yeast, prepare the yeast according to the directions on the back of the package. If you chose a dry active yeast, you will need to add it after the wort has cooled, step 11.
  2. Put grains into a grain bag or muslin bag. Heat 2 gallons of filtered water along with Brew Saltz to 160° then turn off heat and add grain bag. DO NOT add grains to water above 165° F.
  3. Let temperature rest down to to 152*F, stirring grain bag gently from time to time. Leave pot uncovered during this time. Hold temperature at 152 -154*F for 20 minutes.
  4. After 20 minutes, slowly heat back upto 160ºF while stirring grain bag gently.
  5. Remove grain bag and rinse grains over brew pot by slowly pouring 2 cups of HOT tap water over top of grain bag. Let bag drain over brew pot and discard grains. DO NOT squeeze grain bag.
  6. With the heat off, add the 6.6 pounds of the liquid malt extract syrup and stir. Turn on heat and while stirring bring to a boil.
  7. Make note of the time the boil starts and add 1 oz of Hallertau Hops. Do not boil too hard, make sure it is a calm boil.
  8. After 30 minutes of boil time, add the 1 oz of Tettnang Hops. Continue to boil for another 20 minutes.
  9. After 50 minutes of total boil time, add the 1 oz of Saaz Hops along with the Irish Moss and boil for a final 10 minutes.
  10. Cool the wort and add to fermenter on top of 2 gallons of very cold water. HINT: 8 lbs of filtered ice = 1 gallon of water.
  11. Top off to 5 gallons. After the wort cools to 80° or below open the yeast package and pour the contents on top of the wort.
  12. After fermentation has started, about 12-18 hours, lower temperature down to 54-56ºF and ferment for 10-14 days.
  13. After that time, bring beer out of cold enviroment and rack into a secondary fermenter. Bring beer back to room temp for 8-16 hours allowing for a diacetyl rest. This reinvigorates the yeast so it metabolizes by-products such as diacetyl excreted during cold fermentation.
  14. After this, place the beer back into the cold enviroment and ferment for another 10-14 days or until final gravity is 1.010-1.012.
  15. To bottle, rack into bottling bucket. Heat 12 oz of water and 3/4 cup dextrose in microwave for 2 minutes then add to bottling bucket. Stir together gently and thoroughly. Bottle and cap. Store at room temperature 7-10 days. Chill as needed and enjoy!
