A recipe says to mash for 90mins @ 67C then an out time of 10mins @ 75C.
Is the 10mins out time seperate to the 90 mash time or would I do the out time at 70 mins to make it a total of 90 mins?
If you have an easy way to raise the temperature for mash out (ie. direct heat mash tun, BIAB, Grainfather etc.) then go for it, but otherwise I wouldn't worry about it.
