Well I'll have first tasting reports a bit later this morning .. as I unload this truck .. oh boy am I looking forward to today...

mmmm real beer

:beer:


Well Thursday diden't go as planed so no beer was tasted, but the truck was unloaded . Bugger.

Yesterday however was a much better day. My BIAB ESB was conected up and even tho it started out a bit undercarbed the taste was great . The missus and I enjoyed a bit of an arvo session on it after a shake up and gassing. For my first AG I'm rapt. I now have a new keg fridge and will be able to store 4 cornies cold so the under carb thing should be a thing of the past.

So a thanks to Ross for the grain and recipe, a thanks to Pat for the BIAB , and a thanks to all the board members who have encoraged and assisted in the change to AG ..
:beer:
 
We were wondering what happened to you Bunyip. Glad to hear all is going well. Also good to hear Adam found using the big bag on his 2nd BIAB a lot more successful. Thanks to Zizzle and hughman for their feedback as well.

Hey Bunyip. How do you work the bag in a keg-shaped vessel? How do you suspend it and stop it from tearing?

Next brew I do, I'm going to try some step mashing. Will let you know how she goes.

Cheers
Pat

Its good to be home in the north Pat, the rat race just dosen't do it for me... :ph34r:

As for the bag in a keg like vessel; I have "C" section floor joists above me so I have a pully set up to lift the bag above the wort level and let it drain for a few minutes then as the grain is at the bottom of the bag I need to grab the bag and tilt it side ways to fit it out of the opening. The hole in the top has very smooth edges so no catching or snagging. My bag was sewn down one side and across the bottom, it has 2 passes along the base and around the corner but only one up the full length of the long side(will add a bit more after lucas's post) but I have no sign of any pulling. I have a draw string in the top that holds the bag open around the keggle and then closed to lift it out. When out I hang on a cross brace of the house and let drain till the boil starts then just add the 1/2lt or so to the boil.


The ESB has been flowing freely since I got back , its proberly a bit dark and heavy for a full on session beer that I would normaly brew but VERY close to the best tasting brew I've ever made. I'm converted .. :excl: I will brew more along this line but for next winter.

My Crank& hasent got here yet (missus checking mail this arvo) so I go and look at all my grain 3 or 4 times a day and wish... Next month will be big on the BIAB. I need to stock up befor the floods ect ect and cant wait to find a recipe that suits the quaffing /guzzleing tropics... many hr s spent playing around in beersmith so far and lots more ahead by the look of it...

:beer:
 
Received my grain, yeast and hops from Ross on Tuesday - his service is fantastic! So that forced me to go out and get the bag bits and pieces yesterday. The last day or so I've made up a shoddy (hand stitched) bag, but made in such a fashion that there is only stitching around the top (really only there to stop fraying) - kind of like how your Grandma used to do plum pudding! I also took some left over material and made a couple of hop bags.

I have a question about hopping - Is it OK to leave hops that are added during the boil in the pot, or are they removed and replaced by others at later stages? I'm guessing they stay in, but thought I should check, as this is my first AG!

I only have a 20 Litre pot at the moment, so it looks like I'll be splitting my recipes in half and doing 2 boils to get the full fermenter - or is there a better way?

Brew number 1 will be Andrew Clark's Coopers Pale Ale Clone, which I have made up a yeast starter from some real CPA.

Brew number 2 will be Steve Archibald's AG Pilsener.

Hopefully I will get a chance to do these tomorrow, but if not the weekend looks good! Either way, I'm about to jump head first into AG........................ :lol:
 
Good on you Morrie for diving in. The hops stay in all the way through. You can even leave them in while cooling the wort. Your hop bags should work well to stop a lot of unneccessary trub.

To be honest mate, the small pot is going to be a bit of a *******. The upside is that when you get a big pot, you'll find the process a dream.

The problem is if you do it in 2 hits, it's going to take forever but with the 20 litre pot I'm not sure there's an alternative. I'll think on this a bit and send you a PM in the morning.

Think, think, think...
Pat

Hey Ned, thanks for the report mate. I reckon Batz's Kin Kin Ale is the recipe you are chasing. I think I drank a keg of it! Will send you a mail in the next few days.
 
I only have a 20 lt urn...
I cut the bottom out of a bucket (from the bakery about 10 lt cream buck) to size of urn....Then welded the bottom part back in ..
Used a solder iron and melted the plastics together....Drilled holes....
I have a larger type of system in progress...not ready yet....
PJ
Still vote for the bucket.... :beerbang:
 
Pat - took your advice about not splitting the batch in half. My catering mate who I was going to get a large (40 litre) bucket off was too busy for me to go around today, so I looked around the house and found my 40 litre esky. Thought this would do the trick, so I've put 30 litres of water that I heated to 68 degrees and added my grain bag. Unfortunately my grain bag isn't big enough to close with 5 Kg of grain in it - didn't expect it to expand that much when I opened the vac pack! Oh well, I guess I'll filter out any bits as best I can before it goes into the boiling pot! It's good to have the 1st AG brew underway, although I was planning on starting at 12, that's what happens with a newborn around the place. I'll obviosly be boiling in 2 batches due to my small pot, so I'll let you know how it goes!

Cheers,

Morrie, cracking my AG cherry! :super:
 
I have just started doing partials and was a bit impatient to get the first one going. Got all my ingredients from the LHBS, went strait home, got set up to brew and realised I didnt have anything to put the grain in.

As you can imagine I was not happy and there was a fair amount of swearing. My wife walked into the shed to see what all the fuss was about and I had a sudden brainstorm. She was wearing (among other things) a pair of stockings. I talked her into sacrificing a (clean) pair to the beer gods.

They worked great. Although not technically brew in a bag it is close.
 
Might keep the stocking idea in mind if I get stuck in future!

Well, the first boil is complete and now in fermenter. Ended up with about 12 litres in, so not too bad. I've now been kicked out of the brewery/kitchen, so that dinner can be cooked, so I'll have to wait before part 2 is underway. It's sitting in the boiling pot waiting to go. Once that is all done I'll get it into the fermenter and leave overnight to cool down to pitching temp, which I'm aiming to be around 18-20 degrees.

At least the break between boils gave me some time to clean up a bit. All in all, I'm quite happy with my first effort and looking forward to trying the finished product! Thanks for everyone's help and advice that Ive picked up on this forum.

Cheers,

Morrie :beer:

Ah! It's all good fun Morrie!

Didn't realise you had an esky so good call on using that except for the bag bit - lol! (Anyone following this who wants to brew in the bag needs to make sure their bag is big enough to 'line' the vessel they are using.)

Bloody proud of you Morrie (and you others) who are leaping in with enthusiasm and with no direct guidance. I can't imagine doing my first all-grain without help. You guys are pioneers and we have all learned a lot from you.

Morrie is the most recent I have learned something through a PM he sent me last night and that I replied to this morning. And I've just realised something else now. It looks like there are a few more possibilities to BIAB than I thought before for those with small pots though there is still a time cost.

For example, if you only had a 20 litre pot, but had an esky with a tap, you can just make a bag for the esky and mash in that. Drain into your 20 litre pot and do 2 boils.

I won't write much more tonight on this as I've had a few beers with my concretor mates :blink: however, for those with very small pots who are desperate to give AG a go, then reduce your mash time to 30 minutes* instead of 90 and your boil to 60 instead of 90. It's not a big issue.

What I might do for those who are interested and only have access to small pots is copy Morrie's and my correspondence below and see if any of you guys get some better ideas. (Hope Morrie doesn't mind me copying his PM. It's something I don't normally do Morrie! )

Cheers
Pat

*I have more to say on this but not tonight - you can even get a better beer I think???

Morries Correspondence on Small Pots...

Thanks for the advice Pat - I know I can't afford a larger pot ATM, so I may have to look at another alternative if you think the small pot will piss me off too much. I have a mate who is a caterer, so I could grab some large buckets off him - would I be able to get away with doing single batch in a large bucket, wrapped in a camping matress to keep the heat in, and pray to the beer gods that I won't need to heat it up at any stage? I guess I could add hot water if required, but from what I've read the temp seems to be stable with this kind of setup, and the critical time is the first bit. Anyway, I appreciate your help and look forward to what you think.

My Usual Long Reply (5:00am this morning!)...

I reckon that's a good idea Morrie - like the way you're thinking! Get a 40 litre bucket (60 might be easier).

1. Chuck your bag in the bucket (Edit: make sure it fully lines the bucket!) Heat up as much water as you can in the 20 litre pot to mash temp plus one degree and then jug or syphon this into the bucket until it's safe enough to lift and pour.

2. Throw in all your grain and give it a good mix up on and off for the next 20 minutes. Meanwhile, heat another lot of water in your pot to mash temp plus one degree. When ready, just add this water to the large bucket and repeat the on and off stirring for 20 minutes. Time your 90 minute mash from when you added the first lot of water. This method should save you mucking around with insulation etc and should work fine.

You'll still have to do 2 boils with half the hops in each boil unfortunately. You could knock the boil down to 60 minutes instead of 90. This won't matter much and will mean you won't have to use as much top up water at the end.

Put some thought on how you are going to transfer the wort back into the pot etc as the mash bucket is going to be bloody heavy. In other words, see if you can get the mash bucket higher than where the pot is going to be sitting.

If the mash bucket has a tap, just attach some hose to that to drain it into the kettle. The good thing about this is that you won't have to remove the bag at all - cool.

Etc...
 
No dramas about the copied PM Pat.

Just started my 2nd boil, so about to get back and check it.

Just a quick question Pat - what's the best way to clean the bag at the end of it - found the grain wants to stick to every nook and cranny known to man!

Cheers,

Morrie

Peels, I think I might have done some creative editing there - whoops!

I've never done a partial but can't see a problem with the stockings. Have seen some threads on here previously and I think some brands are better than others (this is serious - no colour run etc.)

One thing I've been meaning to post and you've reminded me of is when I did a Google search some months ago on bag brewing etc all I found was an organic site that did the mash in a 'sock' rather than a bag. I remember it said you had to keep it moving pretty much all the time. Tried to find it again now but couldn't. Did find these though....

Organic Sock Brew
This one shows what looks like a liner

If anyone has any time on their hands and can find links to BIAB, please let us know.

Spot ya,
Pat

Good to hear from you! Hope you haven't been drinking as this makes the chill VERY long!

To clean my bag, I basically hold the bottom under a tap (preferably a shower head) and run it from side to side working the grain down to the opening. If you brew indoors the shower is best. Just hold it against the tiles and the spray seems to do most of the work. Turn it inside out to finish off and then just throw it in the washing machine (make sure you tie the draw-string first). The one or two bits of grain left by the shower seem to dissapear in the machine.

I've actually found the bag cleaning surprisingly simple with that Swiss Voile. Takes way less than 5 minutes under the shower.

Once again, stitching is probably an issue. I did get one brew recently where grain somehow got caught in the drawstring seam - no idea how??? Took about ten minutes to get the grain out but got there in the end.

I'm having a 2.5% Schwartz in your honour right now Morrie. (Won't say what I had before - lol)

:super: Pat
 
I thought you must be on the light stuff by the length of your posts tonight...lol

I'm only on my 3rd beer, which is a Coopers Canadian Blonde that I kegged a couple of weeks back. Just had a thought, that this, along with a Mexican Cerveza I also have, might be the last K&K I have in my kegs for a while. :chug:


I'll have an intimate shower with my bag later on Pat, I have to buy it a few drinks first!
 
Just thought I'd let you know that it's currently snowing in Hobart, so if the brew isn't down to pitching temp by the morning then I'll chuck it outside! :blink:

We better start a poll. Do BIABer's have a great sense of humour or what? Only two answer options - defintely and unequivocally.

LMAO Morrie.

I sort of was on the light stuff but maybe a lot of it. Just wrote my first and last essay of the night here

Going to have some tucker now and run away from AHB.

Good luck Morrie. Drink up - you're on the home run and I want to wake up to some amusing posts ;)

i've just poured my first BIAB pale ale and thought i would post the results:

1. forgot the whirfloc for this one so it is quite cloudy

2. it's only been in the keg 4 days so (as above) it is quite cloudy

3. i overhopped it somewhat with my off-boil hops (left them in while it cooled down with the no-chiller method)

i must say it does kick ass though and is a lot nicer than the kits and extracts i was doing. hard to describe, but very fresh.

my next BIAB pale ale will be ready to sample from the keg this time next week and will also be 4 days old. this time around i remembered the whirfloc and held back on the off-boil hops (only 40 minutes this time)

i'll report back next week, both on the matured BIAB pale ale #1 and the new BIAB pale ale #2.
 
4th beer for the night has just been cracked, and I can finally put my feet up.... :D

OK, 2nd boil is complete and has just finished being poured into the fermenter. All up, it's around the 21 litre mark, so it's looking like a keg and maybe a sample bottle or 2. I'll put together a brew log with more detail when I get a chance. I'll take a gravity reading tomorrow before I pitch to see where I'm at.

I just want to thank everyone on this forum, as I've gone from my first brew in January, to my first AG just 9 Months later. I'm sure that if Pat hadn't started this mad thread, then I would never have had the balls to jump in to this so early on in my brewing career! I've also got Ross to thank as well, as his excellent service has provided me with what I needed to get to this stage.

Maybe next year's Indy could be a good AHB meeting place! I'm sure the talent pool will increase ten fold, now that rumuors are alive and well that Brad Pitt made an appearance! :p

I used to wonder how people's brew days took so bloody long, but now I know. I think I started the process around 14:00 today, and I've just finished! All up, taking away dinner in between, and I'd say I've put in 8 hours to come up with my first AG - I think I'll put her to bed now and wake her up with a nice breakfast of Saflager S-23!

Cheers,

Morrie

:D
 
Recently cracked my first BIAB all grain beer.

Was Doc's Choc oat porter.

Even though it's only been in the bottle not quite three weeks, I couldn't resist the temptation!

After the erratic mash, I was a bit concerned that this would not turn out too well, but the flavour and mouthfeel are better than I could have ever expected.

I'm sold.

Bottling the BIAB APA today. :party:
 
You got there Morrie! Congratulations!

You'll find the process a lot less time-consuming and easier once you get a bigger pot so you have a lot to look forward to. You've done very well to brew a full batch from your small pot. :beer:

I was thinking that next time, maybe you could chill the first half rapidly in an ice bath or something and pitch the yeast to decrease the danger of infection. Cool the second batch as well and then just add it in.

Maybe you could use an ale yeast like US-56 to speed things up as well or is it too cold down there?

Top stuff Morrie!
Best regards from Brad Pitt ;)

Great to hear your first one is 'kicking ass' - lol. I ended up with one cloudy brew as well a while back though I'm not sure what caused it - started brewing at 5:30pm - big mistake! In that one I forgot the whirfloc, no-chilled it in the kettle overnight as it was so late and possibly syphoned it immediately after moving the kettle. That's why I put in the spreadsheet to let the kettle sit for ten minutes before syphoning. I must ask Weizguy if the no-chilling is a factor here or not.

Can't wait to come over and empty your fridge!

And Maxt is drinking too :super:

Really pleased to hear that Max. Did you find your second bash (the APA) a little easier than the first as in maintaining temp and getting correct volume?

Once again, am extremely impressed the way Max and all you others have jumped in without the one on one guidance.

Cheers,
Pat
