Indoor BIAB

[Gavin C]

With my latest brew yeaterday (Yooper's Oatmeal stout) I decided to try a couple of things I had not previously done.

1: I used Bru'n water to calculate water adjustments on foot of a Ward Labs report I recently got
2: CaCO3 was added to raise the Ca (this was a bad idea as I have since discovered)
3: Lactic acid was added to the mash to lower the pH (I do not have a pH meter yet so was a bit scared to take this blind and probably ill-advised approach. Amount based on Bru'n water calcs)
4: I used reflectix to insulate the mash and intermittently stirred (3 times) during the 60 minute mash at my target of 155F

The result was a mash efficiency of a hair over 90%. Fortunately my ensuing BH eficiency and FG is still well within the style guidelines (1.056) and should still result in a beer reasonably close to the author's intent.

The Reflectix was very effective at keeping heat in the mash even with stirring no temperature drop was noted. I used my ugly orange jacket to insulate the lid as I haven't got round to adding the Reflectix yet

I harvested a slurry from an ESB the day prior to the brew. I didn't rinse it at all. Just collected 6 mason jars (1/2 pint) of slurry and pitched 2.

Up until now I have rinsed my yeast prior to harvesting. This was easier.

Loving this pale ale from Yooper. Highly recommend it if you are looking for a good hoppy APA.

Thanks Yoop!

My first brew using a pH meter was this morning.Hach Pro+. This is one of the pH meters @AJDelange has recommended in various posts in the brew science forum.

In addition to the meter I purchased the following

From hach.com
Buffer solution pH 7.00 in pillow form
Buffer solution pH 4.01 in pillow form

From amazon.com
Storage solution
Cleaning solution
Small borosilicate beakers in which to mix

From thermoworks.com
A green Thermapen on sale for Paddy's Day

pH Meter and associates


Being new to the meter and not thoroughly doing my homework I was unsure of the steps involved but assume prerequisites are an accurate water report; I got a Ward Labs report a few weeks ago, and a water chemistry tool; I used Bru'n Water.

The pH meter was easily calibrated using the two solutions.

Calibrating the meter with pH 4.01 solution

A mash sample was taken 5 minutes into the mash and read 5.5. This was inline with what Bru'n water had predicted.

Using the software tool I calculated a required addition of lactic acid targeting a pH of 5.3-5.4 (seems to be a decent target for a blonde ale but I am a novice so am open to corrections)and checked the mash 5 mins after its addition. The pH was a hair under 5.3 so some work is needed on my part.

Adjusted mash pH


Perhaps the timing of my tests is off. I was keen to take an early reading as this was to be a 40 minute mash and I figured if I waited too long conversion may well have taken place before the addition of the acid. Based on some recent posts by @RM-MN it very well may have.

My mash efficiency was my highest to date at a hair over 92% and ensuing BH efficiency of 83% (rounding to nearest point)

I had chosen a light beer, Biermuncher's Centenial Blonde so as to allow for a possible higher efficiency than my estimated 75%. The result will still hopefully be a tasty easy drinking blonde ale with an OG just a little higher than planned at 1.045

Any pointers would be greatly appreciated.

It can take 20 minutes to reach equilibrium regarding pH. The point isn't really so you know when to make on-the-fly adjustments, but that you have a real data point for your system, water, and malt for adjusting the acid on the next batch. AJDelange even talks about making a mini-mash for that very reason.

I usually pull 3 samples: from the beginning, middle, and end of the mash.

Absolutely right. Definitely more applicable to future batches. For my first batch with the meter my process was somewhat lacking I fear. I am doing a similar brew with pilsner malt next so will hopefully be able to apply the data from this batch to it. The blonde ale will be ready to taste in a few days. I'm interested to see what the results are from a taste point of view. (I am no expert however so that will be very unreliable subjective data).

 

[Gavin C]

Brewed Yooper's oatmeal stout. I would recommend this to anyone looking for a stout recipe to brew.

Unchanged Grain Bill. 80%eff brought the OG a little higher than planned.
Minor alterations to the hops to get the desired IBU's

OG 1.056
FG 1.017

WYeast 1028 slurry used

Creamy Oatmeal Stout

Is the cooling rack stainless or just chrome?

Chrome. It's held up very well though. No rust yet. Ive been meaning to upgrade and just got this one today. Will be using it in my brew this weekend. I will update the thread once I get it.

 

[pricelessbrewing]

Jealous you get to brew all the time.

 

[Gavin C]

@Biermuncher 's Centennial Blonde. My version with a couple of minor tweaks.
Reduced grain bill
Adjusted hop schedule to target the same IBU's
S-05 instead of Notty
Shortened Mash

OG 1.045 FG 1.010

Tasty and Simple. Nearly 1 million views can't be wrong.

A Munich Helles (recipe with some tweaks courtesy of @brulosopher ) Recipe Here

Used WLP029 fermented at near lager temperatures with a passive rise once 50% attenuation had been reached (SG at 1.023)

OG 1.048 FG 1.010

This was a very crisp beer with a big fat foamy head. Only wish I had given it more time to lager. Brewing it again soon with a lager yeast to compare the results. WLP833

A 30 minute sacch rest at 150F with a 5 minute mash-out at 168F

On a bit of a German beer kick at the moment.
Brewed a Kolsch with a step mash today. Quite a bit of work during the mash but fun.

Next up is the Helles again, then an Alt, Dunkel and an Oktoberfest/Marzen. Looking to try my hand at some traditional techniques on some less forgiving styles.

Sorry if this is of topic for the trend of this thread, but I have a couple of questions. I teach home brewing, and have been looking at biab as a less equipment intensive means if getting people into the all grain side of the hobby.

Any idea what btu or stove is? I can't see mine boiling 7 gallons in any kind of realistic time frame.

The rest is to do with your chiller. Do you have problems with break material in the chiller? How do you clean it? Have you considered or tried a whirlpool without the chiller, before introducing the chiller to the loop, to prevent break material from getting in there? Do you whirlpool then let it sit, or go straight to chilling while whirlpooling?

Again, sorry if this is somewhat off topic.

Not off topic at all.

I'm not sure on the exact model of my NG stove but a similar one on the manufacturer's website has a central burner with 18,000BTU. I'm guessing mine is similar.

A rolling boil of 7.5 gallons is no problem

When cooling with my plate chiller I usually run the wort at full throttle and recirculate with a whirlpool of sorts. I do this to augment the cooling and make no effort to capture cold break. It all ends up in the fermentor.

Thankfully I have not had any issues with blockages in my plate chiller. Hop particulate is more of a concern. I retain this with a hop spider.It seems to work very well.


The hot break is a different beast. It is much firmer and can be scraped off the surface of the wort at the start of the boil if desired. I did just this on yesterday's brew. I have no idea as to the merits of doing this.

Here are some images from yesterday which will hopefully help illustrate my process.

Nice post Gavin, I'm envious of your attention to detail.

Additionally I'm also envious of your stove haha, not your average residential equipment by any means. Fwiw I occasionally stovetop brew 15.5 gal on commercial 6 burner stove....world of difference.

Thanks Wilser. I do enjoy the process. I am fortunate in having such a good stove. It's still a lot slower at heating than a banjo burner or something similar.

Would love to see a pic of that mammoth stove-top brewing next time you get to do it. Something like those massive noisy burners you see under woks in asian restaurants perhaps?

What changes did you make to the recipe. I was looking at brewing that this weekend?

I adjusted the grain bill to acount for my batch size of 5.5 gallons and my projected efficiency at 80%

I also subbed some acid malt for some pilsner malt to get the mash pH lowered.

Hallertauer Hops were used with the same IBU's targeted.

All very minor things to account for my setup, hops I had and desired water and mash profile.

A very tasty refreshing beer. Making it again soon.

My second stab at this great beer recipe courtesy of @Yooper

A few insignificant minor changes to get the hopping to target and a little acid malt (<3%) subbed in for some Maris Otter to lower the mash pH

What a great picture! That looks good enough to drink, and the lacing looks awesome.

Thanks for showing the photo- I love it!

That looks delicious. Which recipe is that? Yooper just has so many :rockin:

It is Da Yooper's House Pale Ale

It's a great recipe. I think it turned out pretty well both times.

i was able to get 7+ gallons boiling on my stove. it was a pain when it came time to pull the grains out. I had to get on a chair. but it worked alot better than i though it would. my stove is gas and fairly new. I will use a turkey fryer next time though. the lower height should help some.

Why not mash with your kettle on the floor and then pull the bag out? That's what I used to do, and just pick up the kettle and put it on the stove top when the mash is done.

True, I don't know why I didn't think to do that. Brain fart I guess.

Are you using anything to support the bag after the lifting. I use a big collander to hold the heavy wet bag prior to squeezing it. I don't have to work too hard that way.

Squeezed Bag in the collander atop the pot.

 

[jaydlaw]

I have an idea for the next time. I don't have a colander big enough but u use the steamer insert and I have a broil pan that I can sit the sterner atop of

I've been brewing a few German beers of late and decided to try to tackle some more complex and traditional mashing techniques with my simple BIAB setup.

My Mash Schedule for this beer


I'm doing this, not to target higher efficiency but to see if the processes are feasible with my setup and to see if they impart any notable benefits to my beers.

Here is my iteration of
Tiber's Perfect Kolsch with some minor tweaks. Acid malt added as needed and altered grain and hop bill to account for my systems' parameters. Thanks to @Tiber_Brew for the helpful pointers prior to brewing. It was very much appreciated and enormously helpful.

OG1.046 FG1.010 IBU27 SRM3.8 ABV~4.7% Crisp and Refreshing

I fermented this in the low 60's with a ramp toward the end to optimize attenuation in search of that crisp dry finish I was after.

Fermentation Schedule



I will be entering this beer in a local competition or two in the next few weeks. I have never had a Kolsch so have no yardstick with which to compare. I sure do enjoy drinking this though. I would highly recommend this brew. Thanks again Tiber.

 

[Psylocide]

So... any notable differences from a simple infusion mash that you can pick out?

Nice looking brew.

 

[joshesmusica]

I'm sure it would make for a hefty brew day (or back to back brew days), but I would be interested in seeing a comparison between the step schedule and a single infusion mash side by side.
Unfortunately I don't have the equipment to do this really, so I'm just another one of those guys who suggests an experiment without being able to contribute...
