Title: big mouth bubbler
Post by: Wort-H.O.G. on January 23, 2015, 12:05:09 AM
we were talking about this on another thread..cant remember where. someone mentioned problems with it and it wasn't thick enough glass.

looks like v2 is out with thicker glass and few other features. i have the original and havent had any issues, but the new features are good to see....gallon graduation marks.

Kind of comes down to plastic or glass here. I've always used glass and so I do like the wide mouth for cleaning, and no samples need to be taken as I just drop the sanitized hydrometer in and take my reading.

I think they make a plastic version of this also.

I gave one of those a hard look last year, but ultimately took a pass.  What is the weight on the glass version like?  Are we essentially looking at a carboy from a weight standpoint?

I don't know about the new version, but original is lighter than comparable 6.5 gal carboy. I've got about 6-7 brews thru it so far.  I think someone had said people had issues with them breaking...have not had that problem.

Thicker reinforced glass is a plus...probably grab one soon.

I have both the old glass and plastic versions.  So far I've still had to draw samples as krausen residue blocks my view.  I wish the glass version offered a dual port lid, a feature I like on the plastic. 
One thing I don't like about the wide mouth on either is it doesn't fit on the keg washer, but it is still easy to clean. 
The key to using glass is to always put the carry harness on it prior to filling.  I still use carboys as well when needed.

Yeah one feature I wish the lid had also was dual for thermowell.

I'm in the pro-glass camp.  Yes, it carries a risk, but so does boiling 5+ gallons of liquid with a propane stove.

I haven't taken a gravity sample from a primary fermentation in so long that I do not remember when I last performed the test.  I can pretty much tell when attenuation is complete by observing the fermentation (which is one of the reasons why I like glass).  I still use a secondary fermentation vessel because I have limited keg space.  I usually take a gravity sample at racking and another at kegging, rarely to do the readings differ.

What keeps you from drilling the hole you want?   That's what I was thinking I'd do but having one in your hands you might see something I don't.

i do it for different reason....more geared to new yeast or recipe and i like to keep notes on performance.

its a much smaller stopper- would not work. they need to make the stopper same size as reg carboy.

The shape of the lid would probably allow you to drill a hole to fit a standard carboy stopper next to the factory opening, but it would be snug.
The factory port isn't even wide enough to get my thief in. (Not an issue with the plastic version)

yeah thats why i was hoping the designer/manufacturer started thinking like a brewer and considered the port size.  cant tell in any pictures if they addressed this with the new evo 2

I was looking for the same thing.  They list an accessory blowoff tube as 15/16" OD so it doesn't look like that changed.

So just picked up on you saying the plastic version has standard stopper / port in that lid. wonder why the heck they didn't do that on the glass version...you would think production would be same lid for both???

I'm considering going back to glass carboys as my main fermentation vessel.  I have equipment now that practically eliminates the worries I had before. 
1) dropping while carrying - nylon harness goes on before filling for lifting, furniture dolly instead of carrying.
2) dropping while aerating - yes, I actually used to shake a glass carboy with a solid stopper in place... just stupid... I use pure oxygen and a .5 micron stone now
3) dropping while cleaning/sanitizing - Mark's Keg Washer.  Hassle free.

Post by: Wort-H.O.G. on January 23, 2015, 03:09:56 AM
Yep I'm the same way. Personal preference and the debate of,plastic vs glass will likely never end...that's ok. I really like seeing what's going on- taking visual cues from the beer vs taking measurements is one plus I like, and thermal properties of glass is another. Wide mouth on this is nice for hop additions and other without need for funnel or stuffing in small opening.

The plastic lid has drawbacks too.  It doesn't use a gasket, so some have experienced sealing issues. 
Also, the lid is a two piece design.  The piece with the ports drilled in it is just a bit too flimsy.  A full size blowoff tube can actually put enough leverage on the lid to create a small gap around the softer blowoff tube, leaving an opening for krausen.

didn't realize the plastic bubbler lid had no gasket and the other issues you listed. glass bubbler lid is pretty sturdy and has gasket-ive not had any issues sealing at all.

I have three of the 6.5 gal. plastic Big Mouth Bubblers.  They are tall and skinny and two will fit in my brew fridge.  I have had sealing issues with all.  However, I have come up with a gasket design that solves the problem.  I'll start a thread with a "how to" and some pictures when I get some time (hopefully soon).

I'll be curious to hear what you think of whatever stainless fermentors you purchase, if you end up going that route.

I am on the fence with stainless because my standard primary volume is between 3.33 and 3.5 gallons. Back in the bad old days when I used an actual Ringwood culture as my house yeast, I used to use a 38.5 quart Vollrath stockpot as my "open" fermentation vessel.  The beauty of the Vollrath stock pots is that they do not have riveted handles.

Have you ever tried fermenting in a 5 gallon corny keg?  You can cold crash without introducing any oxygen (though I know you are not worried about that) and rack under pressure right into the serving keg.

I used to ferment in 10 gallon cornies before I picked up one of these guys: http://www.ssbrewtech.com/collections/fermenters/products/the-brewmaster-bucket

The two drawbacks I found to fermenting in cornies are that the small lid makes cleaning more difficult (though not impossible and not as difficult as a carboy) and you need to either shorten the dip tube or take steps to limit the amount of hop material into the fermentor, otherwise the liquid out tube can get clogged (again, not an insurmountable  task).

that's pretty nifty. 10 gal? any draw backs you've found?

Other than what I noted above, just the price.  I got a decent deal on one through Ebay, the other I purchased as a factory refurb from CHI.

http://www.chicompany.net/index.php?main_page=product_info&cPath=376_1_44&products_id=1073

Good instructions for the keg to keg transfer under pressure (though personally I would never try it with a glass vessel): http://www.thebeerjournals.com/Racking.html

You just need to bend the dip tube so there's a 1/4 to 1/2 gallon of deadspace. I cut a couple and wish I hadn't until I discovered that, duh, you can just bend the suckers. Pretty much relieves that point. Cleaning them with a brush is easy enough. I'd get a couple 10 gallon kegs, but they're pricey. Heard about the chico company ones, but buying a factory second makes me kinda nervous, like it's going to have some sh!te weld that makes it impossible to sanitize.

I think they either didn't have that disclaimer up on their site when I purchased mine or I just didn't notice it, as it would have made me nervous as well.  The keg I received was in perfect condition though.

I have a 5 gallon and 6.5 gallon big mouth. I've only used them once each but I have plans to use these for secondary in the future. They seem like they will lend themselves nicely to fruit additions or dry hopping. Removal of additions and subsequent clean up will be easier.

i've liked my 6.5 gallon glass big mouth. while i've not had any issues sealing or breakage, I'm happy to see thicker reinforced glass, improved lid and seal, and now the gallon graduation marks (all pluses). i would have liked to see standard stopper port, and the round lid would be easier to twist open if it had ears on it to grip.

Put a couple of large (size 36 or 40) SS hose clamps back to back on the outside of the lid to give you something to grip.

He's talking worm gear hose clamps. Biggies. You undo them and combined them, as many as needed to fit over the lid ring, making one big hose clamp. Autopart or hardware store. Once you attach them, the worm gear portion will act as a leverage point.

The lid that comes with them can actually be used as an airlock by itself. You have the option to use a standard airlock with the appropriate bung. There is plenty of room to drill for an access port however, this would force you to use the center hole and bung. I just checked out the new ones on friday. Really like the idea of a secondary port for testing

got my glass big mouth bubbler. compared to original, its much thicker glass-feels the same as reg carboy. but man, they went over board on making that lid fit tight. you really have toge that thing lined up right and put pressure on it as you screw it on so it bites the threads and locks down. they also lined the threads of both the glass and lid with some type of silicone sealant. i get they had complaints with previous lids ( i was not one who had any sealing issues).

love the graduation marks per gallon.
