Homebrew Rig Build

Its time to upgrade our brewing system.  We recently switched over to all grain and 5 gallon batches are not cutting it.  So much time invested just for 5 gallons.  We have decided to move up to 10 gallon batches.  One way to do this is to have a brew rig with three kegs that have been converted to a hot liquor tank, mash tun and boil kettle.  We want to share our experience along the way building the rig.  What works, what did not work and eventually show you the end result.

Parts List:

Hot Liquor Tank

  • Weld less bulkhead
  • 1/2″ ID high temp silicon tubing
  • 1/2″ ball valve
  • 1/2″ pipe fitting
  • Mail quick disconnect
  • Female quick disconnect
  • I have supplies in the garage to make the pickup tube

Mash Tun

  • 2 weld less bulk heads
  • Sparge arm
  • Pump
  • 3 male quick disconnects
  • 2 female quick disconnects
  • 1/2″ ball valve
  • 1/2″ pipe fitting
  • 1/2″ FPT to 1/2″ barb
  • False bottom with adapter

Boil Kettle

  • Weld less bulk head
  • 1/2″ ball valve
  • 1/2″ pipe fitting
  • Male quick disconnect
  • Female quick disconnect

Tools Needed

  • 4 inch grinder
  • Cutting disks
  • Step bit to drill the 7/8 inch holes
  • Drill

Heat Source

  • 30,000 btu burners for the hot liquor tank
  • 60,000 but burner for boiling

If you have any questions about any of the parts send me an email and I will do my best to answer them.

Purchased the kegs off a craigslist

We are always scouring craigslist for any deals on brewing supplies.  I came across someone selling three kegs.  Now we need to cut the tops and start drilling.


Cutting Kegs

Cutting Jig

So many directions this rig can go

Google search brew rigs and you get so many result on how other people have built their brew rig.  Some are three tier, two tier, pumps, gravity fed, fancy this and that.  It will make your head spin!!


Drilling Holes

We used the step bit to drill 7/8 inch holes for the weld less bulk heads.


Cutting holes

Weld less bulk head installed with ball valve and holding water.

We drilled one hole for the hot liquor tank, two holes for the mash tun and one hole for the boil kettle.  When drilling the bottom hole make sure to come up enough from the bottom so the washer on the weld less bulkheads lays flat against the keg.

End Result

    You will have to make a video of the final build. Can’t wait to see it in action.
