Some Notes for the brewer:
Heat up your strike water (for the mash) to 70C. Place your grain bag inside and start adding the grains in batches making sure that everything is mixed into a loose porridge.
Let the grains sit for 60 minutes and stir occasionally to encourage the releasing of fermentable sugars. If you can raise the temperature of the mash to 75C after the 60 minute mash for a period of 10 minutes (the "MASH OUT")
After around 20 minutes begin to heat your sparge water to a temperature of 80C, You can then pour the sparge water over the grains at the end of the 60 minute mash and 10 minute MASH OUT to wash out any remaining sugars.
Once you have reached a pre boil volume of 24L in your boil pot you are ready to start the boil phase.
Once you have achieved a rolling boil you can start your 60 minute timer and begin adding hops in line with the recipe above.
