    Replacement gaskets for Plastic QDs?

    Well that seal wouldn't do anything on gas side, and dump headspace CO2 into the beverage stream on liquid side. So for gas, only matters if using a carb stone pr something!

    Replacement gaskets for Plastic QDs?

    The one with the broken gasket is actually from a fermzilla pressure kit, I think, but basically the same product. I have new "carb caps" and they have that black stem without a gasket. The older ones have red/yellow stems and gaskets. The new one also may be better suited for connection to a...

    Replacement gaskets for Plastic QDs?

    Plastic threaded Kegland QDs have 3 gaskets: post, poppet, and what I'll call "chamber". I believe (untested) that the post and poppet seals are standard. I just took a QD apart and the chamber gasket is broken. This is the gasket that seals the bottom plastic barb to the main body where the...

    Robobrew/Brewzilla Discussion

    There might be some non-linear effects of modulated vs constant volume, regarding the dynamics of the flow, but you'd probably need a 5x or higher peak for it to be significant. More likely is mistaking a probe temperature for an average mass temperature.

    Roughly what temperature is it, and has it been significantly warmer at any point? There's residual CO2 in solution to account for. And do you know how many vols CO2 you want? Here's a handy calculator: https://www.brewersfriend.com/beer-priming-calculator/

    I'm not familiar with conical operations; is there a risk of air bubbles entering when dumping yeast? Or is there enough pressure that it just sprays? On the plastic ones, I figured the attachment container gets purged, but I'm clueless. IMO dumping yeast is not a big deal unless you want to...

    Are you aware that the % pump setting just toggles it on and off? It will suck with full force unless you throttle with the ball valve. May not solve anything, but FYI. I close the ball valve pretty significantly, personally, as I had compaction issues at full flow. I'm trying out the 10-15m...

    Long time no see (Return to homebrewing)

    I mean pilsner malt will generate a lot more DMS than pale. That's what caused issues in my house re smell. That's why I mentioned it! A bunch of people on the forum that don't have 3V setups are not heating sparge water. I've yet to hear anyone say it didn't work out. (It doesn't seem to cause...

    Long time no see (Return to homebrewing)

    Do you live with anyone? I brewed in the kitchen one time while my wife was sleeping. Helles recipe had very light pilsner malt and long boil (lots of DMS). She complained about the smell despite being across the house. I moved outside for the time being (I use a 35L brewzilla) and that solved...

    PP Rigid Duotight Joiners?

    Did they come and go out again? I still get backorder notice on all 4 version (4/6 w/wo valves) edit: You have to select valve option before it tells you it's out of stock.

    I suggest a bottling bucket. Trying to syphon off the trub sounds unpleasant. Or does the fermenter have a spigot? I boil the sugar, pour in to beer in bottling bucket as smoothly as possible. Then I gently stir with a sanitized SS spoon, including an upward sweeping motion. Then bottles with...

    I think you're over-complicating it! BrewMatrix ticks a lot of marketing boxes. You could Call it BrewMatrix4 if you really want to work the number in there. BX4 for short? (Biggest down side to BrewMatrix is BM initialism.) Other ideas: BrewPilot MashMatrix QuadKettle MultiMash I think...

    Aminoacetophenone!

    Finally got around to reading Radical Brewing, and today I learned the grape flavor I hate in corn tortillas and don't care for in some pale beers is aminoacetophenone! That's long been a flavor component for which I lacked a name.

    PP Rigid Duotight Joiners?

    Yeah, I'd like to have ~40psi or w/e for soda. Also different 8-14psi for beers would be a nice perk. I guess I'm just wondering if I'm missing something re the PP Maybe I can buy a bunch of 2" stainless tubes from Bobby, lol.

    PP Rigid Duotight Joiners?

    Im considering getting one of the duotight secondary regulator boards, primarily to have a soda pressure line, but separate beer lines is a bonus. The kit at Morebeer (chronically on back order) is ~25% cheaper than buying components, but it comes with rigid polypropylene joiner tubes. Rigid...

    Zinc usage - amount for healthy fermentation

    FWIW the published dietary mineral content in foods is a "typical" value, and is highly soil dependent.

    Compost bucket sour?

    Batch 3 Lag Time: 8 hr Gen Time: 7 days Final pH: 3.2 FG: 1.022 It's getting accustomed to it's new home. Looked like more yeast this time around. Lots more bubbles even on day 7. How low can pH go?? I'll re-calibrate meter before next reading as a sanity check. I tasted (and spit) some! It...
