    Checking Brewfather recommendations

    Kevin, Yes, yesterday I learned that is correct. I had a feeling that the software had me using too much water. And sure enough I ended up with a batch size much larger than planned for. And the low OG that goes with that.

    Checking Brewfather recommendations

    Oh, that's interesting. So the program is noting that I am using a brewzilla g4 35 and is setting strike volume from that. Which means I should probably just accept that

    Does this work? https://web.brewfather.app/tabs/recipes/recipe/DGgfAKFV6GQI0HzjVu8X1sz74gAR1l

    Checking Brewfather recommendations

    Good morning all, Today I will be brewing with Brewfather for first time. I'd like to see if others can view a Brewfather profile from the link In particular, I'd like comments on the ratio of strike water to sparge water. It's 15 liters to 10 liters, which seems like a lot to me...

    Is the dead space really a problem when doing a full volume mash?

    Bobby, Tell me a bit more about that. You draw off from the low, side mounted accessory drain. Do you run a hose from there, outside and up and over the top and then poking into the pipe lift hole? I can see there are many ways to do this. That is, if you're into recreational plumbing...

    Brewzilla g4 heavy duty false bottom

    I received the answer back from the good folk at Kegland: The heavy duty false bottom is better suited to digiboils more so than the brewzillas as it allow use without a malt pipe. The heat exchanger can be adapted to the heavy duty false bottom but it would then leave your malt pipe...

    Is the dead space really a problem when doing a full volume mash?

    Right. A long thin tube into the interwall space, and down below the level of liquid, and angled to whirlpool. That's the way. for me, anyway.

    Is the dead space really a problem when doing a full volume mash?

    Doug, a follow up question about how to fix it. I get that the interwall wort is stagnant, and I get how this causes some decrease in efficiency. But I don't want to fix the efficiency issue if it means overly oxegenating the wort. So what's the best way to fix it without oxygenating the...

    Is the dead space really a problem when doing a full volume mash?

    The idea of accepting a slightly lower efficiency is a common theme in the AIO community. I think I now understand the move toward AIO. It's a deliberate trade off between a small loss of efficiency and a huge gain in ease of use. Everybody in the community talks about efficiency so much...

    Is the dead space really a problem when doing a full volume mash?

    Yeah, and speaking of oxygen, the method of shoving the recirc hose into the pipe lifting holes, means you are introducing a lot of oxygen. The hole is of course above the level of the wort, so it is spraying against the outer wall and then splashing down the empty space before hitting the...

    Is the dead space really a problem when doing a full volume mash?

    Doug, Ok, I get it. Follow up question. Doing a couple of lift and lowers will homogenize the wort, so I get that. But what about stirring? With 60 minutes of recirc, I would think that the river of hot wort running through the bed would remove any need to stir the wort. Is that...

    Is the dead space really a problem when doing a full volume mash?

    I have a Brewzilla So I have a solid wall mash pipe instead of a bag. And that means that the wort between the walls of the pipe and the outside of the machine, does not move around much. Can be called "dead space" And it's a surprisingly large amount. Since it's on the outside...

    Brewzilla g4 heavy duty false bottom

    Yes, it’s a BZ gen 4. The exit is a center hole at the bottom, and the bottom is concave. Everything is nicely pulled to the middle. But that’s also the problem. Liquid takes the path of least resistance. Much of it flows straight down the middle and avoids the hot floor. The heat...

    Brewzilla g4 heavy duty false bottom

    I thought so. And I also realized that with this, you can't use the heat diffuser plate. So nope.

    120v to mash, then propane to boil?

    Odie, I recall a brulosophy experiment where they found out that a vigorous boil had no discernible improvement over a gentle simmer. And I think the lodo tribe deliberately do simmer, as they feel a vigorous boil will stir in oxygen.

    Brewzilla g4 heavy duty false bottom

    Good morning, all Anybody tried this out? On the one hand it looks impressive. On the other hand, the false bottom that comes with the machine seems to work fine https://www.ontariobeerkegs.com/brewzilla-35l-hd-fb.html

    Low efficiency problem

    Done. And the PID is set up. And what hungup and tracer said, about involving the dead space between the two walls, today I saw that clearly. Twenty minutes into the mash I directed the outlet hose into the lifting hole, forcing the dead wort between the walls, to join the rest of the wort...
