Brewing over 2 days?

[Monkeybrew]

I really want to get my 4th BIAB underway this weekend, but don't have much free time.

So I was planning to do my mash on Saturday morning, then store my wort in a sealed sanitised FV and then carry out my boil on Sunday morning.

How does this idea sound?

Probably fine. I have done a mash in the evening and boiled the next day. I just left the liquor in the boiler overnight with a lid on and it turned out fine. I guess the boil will kill any nasties

[Troutman47]

Not done it myself, but read it's ok to do as Goulders has said.

Yeah, if the two days are consecutive you don't really need to worry about carefully storing the wort, just put a lid on or cling film it to keep the flies out. It will be fine.

I've mashed & boiled the same day, then drained into FV next day only to find it's still a tad warm for the yeast, so left it overnight into day 3 before pitching the yeast first thing. fingers crossed. smells ok though

Why not mash in on Saturday Night (should only take about an hour), and leave overnight - well lagged? Many brewers on the forum seem to do this - Dave Line often suggested it as a good approach.

I did my last brew by mashing and sparging to boiler Friday night then boiling next day.
Only thing I'd recommend (if you dont want it dry) is to mash out at (or heat to in BIAB) a highish temp 76-78C to ensure emzymes denatured and conversion stops.

When pushed for time I've also done AG mash overnight then sparged and boiled next day and it was fine but dryish.

I've done this several times as described by Goulders, mash one evening then leave it in the boiler overnight with the lid on and boil in the morning. Not had any problems with this so far.

Cheers for all of the feedback guys.

I will mash and mashout tonight, remove my grains and then leave in my boiler (stockpot) overnight, and then do my boil early tomorrow morning.

I've done plenty of overnight mashes and it will be dry compared to the normal 60-90 minute mash.

There won't be any real problem with the final matured beer, just inferior in taste, mouthfeel and sweetness etc (in my opinion with my own beers compared).

All these factors are very important organoleptically in finished beer.

Your efficiency/alcohol content will also increase, in some cases, quite dramatically. This of course doesn't mean better beer

Ditto - no probs - just keep the lids on overnight - goes without saying!!

Also ok to drain into sanitised FV then no chill overnight. Pitch yeast day after.

Currently mashing

Would the days necessarily need to be consecutive? For example, if I mash, sparge and run off on a Wednesday, keep the wort in a sealed container, can anyone see an issue with boiling it on the Saturday?

[sbond10]

I personally couldn't see a problem

As an average AG brew day seems to take around 6 hours+, I'm wondering why more people don't do this. Must be missing something obvious
