5 Gallon Brewing Process

Some notes on the proposed 5 gallon brewing process for the office.

Local ingredients: Brew Bristol

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.
