I have just completed a couple of small brews (11.5L) to gain experience of all grain brewing and Beersmith software, and now collating data to dial in my system.
I realise that this topic may have been posted elsewhere but it raises questions on Brewsmith.
The problem I have had on both brews is a sharp fall in mash tun temperature during a mash.
My equipment is a PID controlled 50L boiler, a 33L Coleman Extreme coolbox as a mashtun.
Additional information:
I do not have a sight glass fitted to the boiler so I am transferring the water 2L at a time to the coolbox.
The strike temperature given by Beersmith is 75.2 degrees C, followed by 2 batch sparges at 75.2 degrees C which I diligently followed. (Mash profile added)
I preheated the coolbox with boiling water for 60 minutes prior to mashing.
Problem:
I measured the temperature at the end of 90 minutes mash and it was 56 degrees C (against a profile set by Beersmith of 66 degrees C for 90 minutes).
I am losing 10 degrees C over this period !
I appreciate there is a lot of headroom in the coolbox during mashing and this is something I need to consider. (I purchased the Colemans 33L extreme coolbox as I understood that it had superior insulation.)
Questions:
1 The obvious solution is to raise the strike temperature.
(I have tried to change the strike temperature to a higher value to compensate for the loss of temperature in Beersmith (mash profile page) but this value seems to be fixed.)
Does anybody have any suggestions as to what I can do to either reduce temperature loss in the coolbox during the mash period, or make alterations to Beersmith to compensate.
Best regards,
