Mash in the morning, brew in the evening

[Mad Scientist]

I have a yeast cake in my fermentation fridge that really needs to be used, but I just have not had the time to brew. Since it is going on the third week in primary, I really need to get the beer out of there, and get fresh wort on top.

For a time saving measure, I was thinking of mashing in the morning before I leave for work, then when I get in, add a mash out, and get busy sparging. Or I might run home at lunch.

I know that this is a similar method of mashing in before bed time, and resuming brewing in the morning, which has dangers, since temps can dip into the bacteria range, and then the whole mash is funky.

I am hoping that going to work is a bit shorter than mashing overnight....I also use a 10 gallon cooler, so temps should be held well.

Thoughts anyone?

I sometimes use this method overnight myself, and use a Polarware pot for mashing. By wrapping the kettle with an insulation blanket (top and sides, not bottom) a 150-ish mash is usually 125F + in the AM. This is well above the primary growth temp for lacto, and I have never had a sour character in my beers from it.
I expect you would have even less temp drop in a cooler.
