Mash

Heat sparge water: 3.4 ml per gram of grain (e.g. 3.765kg grain = 12.8L)
Prepare grains in grain bag
Once at strike temperature 70C
Heat off
Add grain bag
Secure grain bag (string/bungee?), lid, cover with towel
Wait 1.5 hours

Sparge

Interestingly a cold water sparge should be ok.

Lift grain bag to agitate
Add cold water to make boil volume
Lift and drip drain grain bag

Boil

Start boiler
Wait 1.5 hours apx
Maintain rolling boil for boil time (1 hour typical)
Add hops at intervals

Cool

Setup buckets with cooling water (4 buckets = 2 cold supply, 2 on hot water drain)
Start cooling siphon before adding wort chiller to wort
Immerse wort chiller to wort
Maintain cooling water as required
Approximately 30 minutes to reach 30C

Ferment

Drain brew by dropping from height into fermentation bucket
Add yeast
Setup bung & airlock
Seal lid

That should be the complete process to get a brew started.

BruPacks Boiler Test

23rd June 2015

We needed to perform a test boil with the newly acquired boiler to find out the general timings of the boiler and test that it can actually perform the task we needed it to.

Our intention is to mash, sparge and boil in this boiler which will make it an excellent addition to the office brewing setup.

The timings collected from the test run were as follows:

10:05 filling started
10:13 filling complete, boil started
11:24 close enough to full boil, cooling started
12:06 cooling complete

That gives us approximately 1.5 hours to boil, 0.5 hours to cool which is quite a managable figure for a 5 gallon brew.

The cooling setup uses a copper immersion wort chiller

We found the siphon action between two brew buckets, refilling the cold supply and emptying the hot worked very nicely.
