Hey guys,
Just been reading through the "how to brew" by john palmer. Great book, and would recommend it to anyone starting out brewing.
One thing that is touched on in the Yeast section is aeration is good, oxidation is bad. It mentions that the generally accepted cut off for hot side wort oxidation is around 27 degrees.
This has worried me somewhat as the kit and kilo instructions appear to create a large oxidation risk/potential in the instructions.
"Dissolve contents of can and other fermentable sugars with 2 litres of boiling water"
Obviously this is hotter than 27 degrees, I would then stir it all up until there are no chunks from the malt, and at this point I add 6-7 litres of refrigerated pre-boiled water and top up to 20-23 litres (depending on the batch I'm making). This finishes at about 22-24 degrees, which would seem ideal for aeration at this point. However, have I already performed a hot side oxidation by following these steps? Should I perhaps add the boiling water, add the refrigerated water, then mix everything up?
Just worried that the process in the can is grossly out ... and I don't want to be ruining all my kit and kilos by oxidation ...
Am I being just too paranoid?
