Sack squeezing and haze

[wilserbrewer]

pm'd wilser about dang time.

Pm received

Brewed today and sure enough one bag has a large square pattern on it. There was a ton of shat in the brew too. Ugh, pm'd wilser about dang time.

I don't follow your meaning here. What's the large square pattern from?

My beers are always hazy until they've been in the keg for weeks. I never cold crash or use any fining agents, but I too squeeze the bag over a cullender. I also "sparge" by spraying the grains with hot tap water.

 

[applescrap]

I am not sure. Maybe a lot of use or maybe it was like this when I got it. Think it might be a mix of both. I'll upload a picture and I think it will be easy to see how bad the weave is. The Weave has turned into a square pattern that is unusually big.

I do biab and I've changed a few things since I've started. Not that I was making bad beers but I am trying to get a feel for the different possible outcomes. I used to squeeze, sparge, and did no kind of filtering of my wort at all.
Now I do a no squeeze and just hang and drain for a little while. Usually 30 minutes to 2 hours depending on if I feel like taking a break to do something. It saves me the strain of having to squeeze.
After discovering a small hole in the bag one time I began double bagging with a paint strainer bag encapsulated by one of the biab.com bags.
For filtering wort I've tried a few minor things which have pretty much wound up being useless in eliminating the break matter that makes into my fermenters.
After doing more research today I am going to try placing a strainer bag in my milling bucket to eliminate any excess loose flour as I've read some people who do biab have seen that cut down on break matter. Also I'm going to try a ghetto version of vorlaufing my wort after the bag drains. I'm essentially going to let the post-mash break matter settle to the bottom of the kettle, which most of it does after 30 minutes to an hour, and utilizing the kettle spigot and a pitcher I'm going to pull from the bottom of the kettle and pour that back through the grains in the bag. I'll let you know how it turns out.

The pic posted is one of my most recent brews. An ipa with two separate additions of 3 oz of dry hops each. One added a day after pitching the yeast at high krausen. The other added to the keg with a clear beer attachment. It was only cold crashed and it came out crystal clear. View attachment 594032

Am I the only one who sees the ghost in this beer?

 

[FloppyKnockers]

I'm a bit hazy since the last time my sack was squeezed.










Not sorry.... I had to.

 

[Gravelscratcher]

That joke is so last year.

 

[Gravelscratcher]

When someone squeezes my sack, hazy liquid comes out.

I can’t give much advice on BIAB as I’ve only done it a few times. However, regarding clarity, I’ve been using Brausol Special finings - gets rid of proteins and yeast in suspension, and therefore chill haze too. Can’t recommend it enough. I use 8ml per 20L brew a day or two before bottling. Crash cooling helps, but I didn’t crash cool at all on my last brew and the beer has turned out nice and bright.

I’m also a squeezer. I use pvc gloves and squeeze the bag while it’s hoisted above on a pulley system.
I ferment in a modified chest freezer, so I cold crash and use gelatin for finings. Beer comes out crystal clear.

 

[Gravelscratcher]

My squeezing comment was meant to be a joke.
I use whirfloc or Irish Moss during boil, and everything drops out...same as 3v.
Edit:
This sounds harsh...not intended to be. Hard to relay tone through text/writing.

Glad this was bumped

Because I felt I owed it to you to show this s..t bag vs a wilser. Look how fine the wilser is. I think this was my problem and first brew granted its a light beer has very little trub. I wonder if those who "try out" biab end up with cloudier beer because of this bag from the lhbs. Btw wilser is very generous and quickly got me bags. Thanks again wilser. Look and see for yourself.

 

[Gravelscratcher]

Wilser bags are legit...very well made & designed.

 

[Ninoid]

I always squeeze, never cold crash (not have setup), sometimes use gelatin, sometime No Boil, sometime 15 minutes boil and my beers is sometime crystal clear, sometime not, but never murky.

I think it depends on the grain type and yeast (FG). My beers is always clear with Saison yeast (BE-134, FG is under 1.005) and lighter grains (Maris Otter). If use Pilsner grains and S-04 yeast my beers is not clear.

A variable without relevance in my personal experience.

 

[applescrap]

Perhaps the variable in question is that pos bag I was using, among other possibilities.

all this sack squeezing talk, I can't stop chuckling [emoji12] I am witholding all other comments for obvious reasons but will be disappointed if someone doesnt take this bull by the horns and run with it.

 

[applescrap]

I don't think the hard squeezing is your problem. Unless you are a lot stronger than me, you aren't squeezing too hard. I squeeze out the wort, add water, squeeze that out, add more water, and give it a final hard squeeze so there isn't a chance of any drip onto the carpet on my way out to dump the bag and I still get clear beer.

sorry, I missed this. You double batch sparge with squeezes inbetween. Doug has given me charts and helped me to understand this process a little and it intrigues me very much. plus I know you mill your grain fine, so what kind of efficiency does that result in? Do you mind sharing how you do that? I am also curious because I remain curious about partigyle with biab. Curious if I should squeeze or how, much, maybe just boil first runnings?

SWMBO has fishnet stockings for Naughty Nights that have smaller holes than that.

Fantastic looking beers and I echo your experience. This variable has no consequence. Grain, yeast however...

Actually I don't double sparge, I triple sparge but using cold water so I don't worry about extracting tannins. My final sparge still gets me above 1.020 to add to the kettle. I have the efficiency set on the software I use to 85% brewhouse and usually exceed that. Some day I might get serious and do some accurate measurement to determine what the efficiency really is but when you get into the high efficiency it doesn't take much mis-measurement to be inaccurate by quite a bit.

 

[applescrap]

Tripple batch sparge has two water additions? Thats pretty hardcore. With squeezes inbetween, that would have to be above 85, let me try and find dougs chart. Here it is. Of note a single batch sparge with no squeeze remains higher than a squeeze up until a ratio. I say I will add more grain since its cheap, but while Im at it, I figure I might as well try to as much get sugar out of the grain within reason.

I am happy to report the bag was clearly the problem. The light beer I just racked was much less turbid than any other. The wilser bag made a dramatic difference surely as a filter.

Just as I read recently from founder of biab pat hollindale, a proper bag is a requirement of biab brewing for so many reasons.

Yea! Feel free to squeeze! Say g'day to Pistol Pat [emoji41]

I wish I could, would love to meet him. I want to hunt and peck around for more of his work. Its out there. Holy guacamole, simple? Did you see his brew log, I posted on another thread? Whoa. I think it's the master Brew log from biab Brewer.

You do know about his website @ https://www.biabrewer.info, right? You can talk to him all the time there. It can be interesting [emoji1]
