Turbid keg

If you're adding silicon dioxide then you better be careful not to inhale the dust when adding it dry as it can cause autoimmune diseases. Got one, they suck. But ingestion - at least in small quantities - has not been proven bad for you.

I went to put my "last one" in the fridge, and way in the back I spotted another "last one". Even though I like them, I'll drink them both and be done with them (though not in a session). Since it's not an advertised - or desired - feature of the beer, it is apparently unintentional, and I want to be done with it. But not going to drain-pour a $12 beer!

 

I had some chunky stouts from a BIF box from @ovaltine, Transient Junie stouts with chocolate fudge chips that melted in your mouth and caramel chips too. Best Stouts I’ve ever had, I was licking the inside of the glass to get every bit of both, I probably looked ridiculous but you can’t help yourself.

 

It's a 30% solution (liquid form). This is a widely used, commercially available fining. The inhalation of SiO2 dust is a totally different thing.

I'm just wondering that during cold crash it tends to gelatinize? Could be the answer to a lot of these floaty mysteries.

 

I am familiar with that activity with Julie.

 

I had yet another Avery Raspberry Truffale. If you saw it, I had one of these Wednesday and posted it on WBAYDN and here. Having found large chunks in this beer before, on Wednesday I strained it while pouring it in the glass, and it looked like . There was some discussion here about what it was, so with this one I strained it again, got the same but instead of just dumping it I tried rinsing it figuring if it were raspberry then the chocolate or whatever would rinse off. But it quickly and completely dissolved, supporting the premise that it is perhaps yeast or or some other particulate that had settled, perhaps along with chocolate. Anyway, the beer is once again incredible despite the at the bottom.

 

There have been a few threads in the past that described this same gelatinous-like substance that was found in bottles. It seems like each time these beers were stouts, but I don't recall if they were barrel-aged stouts. It also seems like each time the topic came up that Founders was the involved brewery. But the concensus was that the substance was just coagulated proteins and harmless. Maybe the brewer at Founders could be helpful if you contact him.

However, your second post describes your fining substance as a "liquid colloidal suspension of silicon dioxide." Thinking way back to my high school chemistry, isn't a colloidal substance gelatinous, and your mysterious substance may just be that stuff? A discussion with your supplier or the manufacturer may produce and answer to your question for you.

You might also consider posting your question in the Homebrewing forum. Some very experienced homebrewers, as well as some occasional pro brewers, hang out there, and they could offer something more definitive than my guess. Good luck on finding an answer.

 

The main point of my post was to perhaps provide some insight as to what these floaties might be. I'm sure there are plenty of breweries that have encountered this type of thing and have labs to analyze it, and know what it is. I'm sure I'll find out eventually.
This stuff hasn't made it out to my customers' glasses (yet!), I try to be vigilant about providing a clean product to my customers. Color me old school.

I have some Central Waters Cassian Sunset that has some globs drop out at the end of the pour but nowhere near as bad as what I have seen in the pictures posted here. I just scooped the snotty stuff out with a spoon and enjoyed.

 

Definitely raspberries stained with stout. That's what it looks like if you ferment whole (or roughly pureed) fruit in a dark beer. Probably some other proteins and yeast globbed on, but I think mostly unfermentable fruit fiber.

Sounds like you got some of the pastry trub. It all depends on how much you got and how big the chunks are. All you can really do is keep pouring to see if it clears (or ask for a refund).

I'm not going to repost, but I found huge chunks of double-stuffed oreos in a Prairie beer last month. See here: https://www.beeradvocate.com/commun...all-football-hauls.582622/page-2#post-6502799

 

It should have settled out now if it’s truly sediment, I.e: yeast, protein etc. if
It’s still pouring turbid I would suspect that there is something bad with the keg and would tell the distributor so you can get something else instead of holding on to the keg.

I homebrew and every year take a keg to a festival. The drive kicks up all the particles as I don’t filter being a homebrewer. If we tap it that night it would be super turbid but by the next day in time for the event it’s settled out. A larger keg might take more time but shouldn’t take more than a couple days max.

 

The latest beer I had, I strained the then rinsed it. If it were raspberry slices I would expect them to hold together and be rinsed off. But everything in the muck dissolved in about three seconds, with nothing left behind.

 

Just having some Cassian, and was watching for it when a glob poured into the glass. I fished out a glob of gelatin about the size of a small marble. I drink Cassian all the time and either never had it before or overlooked it. Beer still kicks ass.
