Overnight Mashing ?

[MashBag]

That's nice, and a cracking example of how we all make it fit & in loads of different.

Ps. I don't think lacto infection is directly proportional to insulation efficiency

Anybody do this and a no chill? No issue with temps for AIO systems/RIMS.

Sounds like you could save hours in the brew house.

Yeah, although I've given up on the overnight mash. Thanks to COVID leading to more working from home, I now brew on a Friday, starting the mash at lunchtime and then moving onto sparge at about 8 once the kids are in bed. Can normally be done by 10, having had two hours of blues and brews on my own.

Yeah, the more I've been reading about it over the last few days I think I'll pass on it. It would save me just over an hour. I'm starting into 'no chill' now so that claws the time back.

That's what my plan was but I'm just going to go with no chill.

My next brew will be a "no-chill" and an "over-night" mash ... of sorts, more a "night-before" mash. But I am considering this "delayed start" over-night mash as there's no waste of heat (my "night-before" method means the wort does get chance to lose its heat before being stepped up to a boil next morning).

I think the method is a reflection of modern "All-In-One" (AIO) systems as they have all the fancy timers to set it up. In fact, some AIO's have even fancier controllers ... mine has a "delayed heat" so I wouldn't need all those "20°C steps" that @MashBag sets up; maybe no recirc until the heat starts either (?). I could do it with my big 3V (HERMS) system 'cos it's controlled by an oven timer, but it would have to be crude (no mash-out or mash steps).

Some discussion as to whether this method saves time?

Maybe? Maybe not?

Of no consequence to me, the method (and the "no-chill") means I don't have to do a big job in one timeslot. For me that is valuable, others may have different reasons, all based on a person's circumstances.

I don't think an overnight mash saves time. It redistributes the work. There's more going on in the mash tun than just converting starch to sugars. The sugars themselves are being degraded to develop a better ratio of maltose and dextrins.

Most of the work in mashing is done within 4 hours but who is willing to wait around that long? Better off let it do its thing while you sleep. You'll be hard pressed to find an old recipe which doesn't call for a two hour mash and a 90 minute boil.

Overnight mash is a good way to get plenty of HSA if that's your thing.

I used to do it all the time Lee, I set the AIO to mash at 9pm by 10pm I had mashed in and then wrapped it in Duvet etc. By 6.30am to 7am it had dropped in temp but not anywhere near the low 50's. I would then just proceed as normal and when the boil was done just let it cool down (NO Chill) ready to pitch by late tea time that day and never had a problem.
I do not do it as often now as I have more free time but I would do it at the drop of a hat if I had to.
Worked well for me and extra eff helps too so I had to adjust my recipes grain wise

Yes I do and more. Yes I do save a lots of time.

Evening -1. Setup BM20 & dough in (20mins)

Morning 1. Boil & hop (90mins) setup BM20 to cool.

Morning 2. Setup BM20 for fermentation & pitch (in the kettle) (45 mins)

Morning 8. Bottle warm from BM20 and wash up. (90 mins)

I think this roughly saves me at least 3 hours.
1 waiting for mash.
1 at least faffing about setting up, using, washing, drying and stowing the chiller.
1 more not pumping to, setting up & washing a fermenter.

Happy days but it is each to there own.
