Buying Ingredients

Northern Brewer

Purchased online on Mar 25, 2014 at Northern Brewer :

The Tue, Mar 25 Northern Brewer order arrived via UPS around 1:00 p.m. on Thu, Mar 27, a little under 48 hours after placing order. If that timeline holds, then the Wed, Mar 26 order may arrive late in the afternoon on Fri, Mar 28. I doubt Saturday delivery is used.

The second package of London Ale Yeast (Wyeast Labs #1028 mentioned below arrived around 5:30 p.m., on Fri, Mar 28 from Northern Brewer.

Titgemeier's

Rest of the ingredients purchased at Titgemeier's Beer and Wine Making Supplies :

On Wed, Mar 26, 2014, I purchased all of the remaining ingredients including the 6.5 gallon fermenting bucket and the airlock. The only exception: Titgemeier's only had one package of the yeast, so I purchased the other package from Northern Brewer. The tracking for yesterday's order showed the package should arrive on Thu, Mar 27. So hopefully, today's one-item order arrives on Friday or Saturday. If not, then I'll inquire about plan B for the rest of the yeast. The grains purchased at Titgemeir's were milled at the store and placed together in one sack. I ordered the Franco-Belges unmilled. Today's Titgemeier's shopping cost a little over $70.

Steps

  • sanitize equipment.
  • determine amount of water to warm on burner.
  • place kettle of water on burner.
  • fire-up burner.
    • need to warm water to 152 degrees F ??
  • mill grains if necessary.
    • setting 35 for Franco Belges.
    • setting 50 for Flaked Oatmeal.
  • want mash-in water temp around 152 degrees.
  • add water to cooler.
  • add grains to water while stirring constantly.
    • ensure no clumps.
    • don't scrape hose on cooler bottom.
    • reach down and lift up grains and then stir back and forth.
  • steep for 60 min.
    • stir briefly every 15 min.
  • with about 15 to 20 min left in the 60 min steep, measure water required for sparge, place water in kettle, set kettle on burner, and warm to 168??
  • after 60 min, drain some liquid into kettle for a few minutes.
  • turn off valve.
  • place this liquid back into the cooler.
  • turn on valve, so that liquid slowly flows from cooler.
  • begin sparge with the warmed water that's on the burner.
    • while holding large sanitized spoon in one hand, pour water onto the spoon to spread out the water so that it gently hits the mash in a fanned fashion.
    • move spoon back and forth while pouring water onto spoon.
    • may need to add more water.
    • will need to tip cooler off to get liquid from cooler.
  • want a little over 6 gallons of wort before boil.
    • obviously, will lose some liquid during the boil time.
    • desire to have 5.5 gallons for fermenting.
  • after sparge has ended, place the kettle of wort onto the burner.
  • bring wort to a slow, rolling boil.
  • when boil begins, that's the 0-minute mark and add any necessary ingredients.
    • when adding hops, the wort will bubble up and if not careful, it could boil over.
    • after adding hops, turn down the temp slightly to prevent boil-over.
    • after a few minutes, crank up heat again to rolling boil.
  • boil time will be 60 minutes.
  • add any other ingredients at scheduled intervals during boil.
  • when boil time has ended, time to cool the wort.
  • with sanitized copper coils, hose, and water, it's time to sit, relax and move the coiled copper rings up and down in the wort. The cool water moves through the rings. Wort temp will start out over 190 degrees, but it will quickly cool. In under 20 minutes, the temp will reach the desired 75 degrees.
  • place kettle of wort on table top.
  • use large sanitized spoon to vigorously stir the wort to create a whirlpool effect.
  • place lid on kettle.
  • let rest of 15 minutes.
  • ensure fermenting bucket and airlock was sanitized.
  • then pour wort from kettle to fermenting bucket.
  • place bucket on table top with no lid yet.
  • add yeast.
  • use big spoon to agitate wort by vigorously moving spoon back and forth, slamming into the sides. don't stir. agitate. this action should cause bubbling on top.
  • after considerable bubbling, pound on lid. place lid on container and smack lid down into place with palm of hand or fist. lid should be snapped securely into place all around.
  • press airlock into lid until it's snug.
  • for all post boil actions, equipment and hands must be run through the sanitizer for at least 30 seconds before use.
  • let bucket ferment around 62 degrees for 4 weeks or so.
