Hi. I purchased Brewzilla Gen 4 and did my first All grain brewing. My wort was cloudy and hazy. After I let it sit, it cleared up and I had a lot of precipitation. I heated up my water to 160, dump my grain, and kept the temperature at 155F. When I was running a pump with a screen on top my unit said the temperature is 164 but when I pulled out the screen and mixed it, it dropped to 155. So I decided to do it without the screen but still had about 2 inches of water above my grains. How do you control it? I tried to close the valve but it still had a good stream. After the mash, I raised the temperature to 170 for 15 minutes but still, my wort didn't clear. Any suggestions? TIA

Some of us don't worry too much about wort clarity. In the end it'll just be more trub in your fermenter.

But perhaps part of your issue may have been the amount of rice hulls you did or didn't use and the crush of your grain. If you are wanting a high mash efficiency, then you'll probably be crushing fine. And that will usually either leave you with cloudy wort to deal with after the boil or a stuck mash where no wort runs through it.

Other than a little bit less malt amounts are needed to get the same OG, there isn't really a need to have a high mash efficiency other than it might save some costs. But you might spend more trying to clean up your wort if you don't like trub in your FV and desire a really high mash efficiency.

I do BIAB, so you'll likely get better advice on your particular set up with later replies here.

Agreed that cloudy wort doesn't mean cloudy beer.

For temps it basically requires good circulation with an occasional stir. Check the grains for the temps, not anywhere else, as they are the main point. Anywhere else could be too close or too far from the heat source and give different, confusing or conflicting values.

That circulation tends to help clear the wort of course but it all get undone with the stirring or when the grains are removed. It's life with an all-in-one.

Didn't use any rice hulls. I got grain already crushed.
I think what your all-in-one is doing by re-circulating the wort is a vorlauf process. So if you weren't getting a very good re-circulation going on, then that to me says you probably should have had some rice hulls in with the grain to keep the starches from gumming together and making it hard for the wort to drain through. The finer the grain crush the more rice hulls you will need.

There are some other things too, but that'd be the thing I'd consider for your next batch.

With BIAB, you don't need any rice hulls at all no matter how fine the grind for most of the ways we can BIAB.
