    When to remove trub

    Well, that is a damn fine looking pils.

    When to remove trub

    I like the idea of the easy yeast harvest. I often do a batch split in half. Take a six gallon recipe and make two batches of three gallons each, and two weeks apart. Then I am tasting the beer when making batch #2, so I know what to tweak. So that would be perfect for the second...

    When to remove trub

    Since my pump drains from the bottom of the bk, I suppose I would just direct the first liter, say, into the sink, then turn the hose into the fermenter.

    AIO working well for overnight full volume

    Good morning all Not saying this is preferable, but it does work well for me. Last night I set my AIO (brewzilla g 4) for an overnight full volume mash. I started a full volume mash at 150f. The Bluetooth thermometer is installed in the mash. The heater is dialed down to 30%. The...

    When to remove trub

    Does it matter when you remove the trub? When you transfer from the kettle to the fermenter, you could just throw out the first liter and get rid of much of the trub that way. Alternatively, you could transfer all the contents of the kettle, trub and all, into the fermenter. Then when you...

    switching to no sparge

    wr, you could try doing a smaller batch. that's what I do

    Does recirc replace sparge?

    Ah. As a scot, I once persuaded my Canadian wife, for about half an hour that we used to go Haggis hunting in the mountains back home. Fast little critters, like small feral pigs, found in the highlands, sadly nearly extinct now.

    Does recirc replace sparge?

    Ok, way off thread here, but enjoying it. As a Canadian, I have to ask, what plant does grits come from? I thought that was corn, but you said bushes? To me it sounds like mythical plants like the spaghetti trees of Napoli.

    Does recirc replace sparge?

    I enjoy your light hearted energy BC Although I’m serious about quantum entanglement. It always happens at the worst time. And usually down in the bottom plate.

    Does recirc replace sparge?

    Oh hell, Doug and I only just starting to get deep.. Next we run some Pilsner two row, through the Hadron Particle Collider to check for quantum entanglement issues.

    Does recirc replace sparge?

    This is supported by the experience of a member here who recently did a partigyle. He thought his second runnings would make a light beer. But they did not. He found it was extremely watery. Too thin to make anything resembling beer. Which supports what Bobbi M has been saying, that...

    Does recirc replace sparge?

    Ok, so we think of the grits as a number of small sponges. Say there are, in a thick mash, ten parts of sugar per thousand, some residing inside the sponges, some on their outside, and some floating free. There is homogeneous distribution. Remove the wort and the sponge content at ten parts...

    Does recirc replace sparge?

    Doug, A main insight for me, is that remaining sugars are inside the grits, not resting on the surface. I had imagined that after lifting the pipe, the sugars dissolved in the wort would fall into the boiler, while the sugars stuck to the outside of the grits would remain stuck there. And...

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

    Good morning and happy Canada Day. Bobby, if I understand correctly, you are happy with a no sparge full volume, but you do go to the trouble of putting in a splitter to capture the dead wall space sugars. Do I have this right? Also, are you making and selling dead space recirculation kits...

    Does recirc replace sparge?

    That's the first explanation I have heard, that really makes sense. By taking out six liters for a later sparge, you are causing the mash wort to be concentrated with sugar. So then you HAVE to wash those concentrated sugars off the husks. The sparge is only solving the problem that it...

    Brewzilla Gen4 Discussion/Tips Talk

    Hey Bobbi M, I'd love to see that white paper

    Does recirc replace sparge?

    I did a full volume mash and the efficiency was acceptable to me, at least compared to a quick pour over. Not compared to a full fly of course, but that's ok. I only did it by mistake. I come from the old days when you absolutely had to sparge. That's why we all had 3V. If you had told...

    Can the pump be involved in a profile

    Can the pump be involved in a profile

    The profile runs the temperature, but I don't see that it can control the pump. Is that right?
