AG Brewing in a Bag

The fine art of beer making is from ground up. Expert talk and wannabies. From mashing, sparging to full boiling.

True Hunty well be in the pudding eating at least.
Forgot about the pumping (which I havent got yet Keat but in the pipe line for next Ozzie visit)
There is an March Pump Agent here but says he doesnt have what I wanted,, queer really.

Will look at doing the RIMS system as U suggest Keat.. Three more Ales in the triakl then I will have to do something about have Stepp Mash available somehow, not all that worried with the addition of the water Hunty as long as the Mash is under Ratio at the start. My trouble is the end Brews I want which arre over the 7.0% range I will run outa space in the Mash tun.
I can always direct heat as U say..
Dreams are free..

Brewing this week end looks like a bloody fizzer as well unless I Brew all Sunday night which I might look at doing yet..

Cheers Spud

A pump for RIMS and transferring wort would be the next upgrade, but not for a long long time..I'm probably dreaming as well . But like you said, dreams are free :mrgreen:

sorry for digging up old thread. :oops:

For BIAB, I understand that the efficiency can be quite low. Due to the constraint of having only a 15L brew pot.
Is it possible to mash a few times. Eg, extract out 3 L of good starchy sugary juice, store it aside. And do that again to create more
juice one desired.
Any concerns for the grain extract storage condition? full boil first before putting aside? or maintaining it at 70degC and combine with the next mash, then bring to full boil?

thks for advice!

I see no fundamental problem with a second rinse, its akin to the sparging that we do in the conventional process.... give it a try. But don't do it at 70 degreec C ;), suggest 63-68 max is best ;)

thks for advise! I was thinking, 70degC water when used to sparge, would become about 68degC...

Regarding the issue of collecting more mash juice, supposed if I could only extract out 4L of mashed juice, to produce 8L of juice, is it possible to do that in batches? Do I have to maintain the 1st mashed juice at mash window temp to preserve it before bringing the whole combined lot to a full 1 hour boil?

absolutley ok to do it in batches. In fact thats what "batch sparging" is. And no, you do not have to retain the ist juice at window temp, in fact you can start heating it in preparation for the total boil while you do your second sparge...

thk u sir, for the advice! 8)
I've just got hold of a 10L bucket, thinking of making a mini 6-8L ( TAD-size friendly ) partial mash + DME. If going at 4L extraction rate per batch, I'll need to do it twice. If not, I'll have to custom make a bigger brew bag to contain about >3 kg -4 kg of grains. :?

Just finished my BIAB Pale Ale yesterday.
My conclusions:

1) yes, it is very easy and cuts off at least half the usual time if not more.

2) On hindsight, I should have immense the drained grist bag into another pot containing 68PC to 70*C water for a final extraction. Whats' the harm? But this time round the water should be much lesser, perhaps only 4 - 5 litres, then check the OG.

The whole idea of BIAB is to cut down time and use minimum equipment. So for those trying it out, go ahead...it is not difficult at all.

I guess BIAB is really a very convenient way of brewing with some grains.
As I've never used convertional method ( using MLT equipment), I'm not too sure how much time one could save.

After I've tasted my prev batch of partial mash Ale, I'm convinced that either mashing some grains into a kit or brewing up
an AG is the way to go. The improvement in taste and quality is worth the investment in time and equipment, :wink:

Fin,

I think the satisfaction in a full AG is the creation of beer from raw material to finish product...know what I mean?
