Alright, I flattened one beer that's already carbonating, checked two others in secondary, made an 8 oz DME batch, and checked against RO water. At the end of the day, my refractometer is more accurate than my eye, i.e. I can't see it well enough to force a correction factor so I'm pretty happy...

Definitely moving to a PID controller and ULD element. I found plenty of other references to starch affecting gravity measurements and it all makes sense, so I agree that it doesn't measure conversion. I got some iodine yesterday and will use this on the next brew, and may play with some...

Wow, I never realized that. I will have to try the iodine. My gut reaction is that I'm converting since the beers taste sweet to me, but this will give me another level of detail. I love data, so I'm an easy sell on something like this.

I don't. But I do check pre-boil gravity and volume. My last two mash efficiencies have been 90% and 93%

I used to agitate, now I have a wand. I generally turn the O2 on just enough for flow and stir the wand near the bottom until the foam fills the dead space in the fermenter. That usually takes 5 minutes or so. That's got to be plenty, right? I have had some really quick and strong activity...

Probe is in the tube, right after the element. My primary suspect is the thermostat also. I considered running multiple steps like 140 & 158, thinking that would allow for the large temp swings. But that still wouldn't help if the element is getting too hot. Thanks for the input!

Hey folks, I've been coming to this site for a while now. I've gotten some good recipes and other ideas that have served me well. I've finally created an account because I wanted to ask a question that I couldn't find an answer to. I've posted that in the electric brewing section, but...

I've been getting consistently sweet beers from my setup and I think it might have to do with my RIMS setup and would like to know if anyone has had a similar issue. I did extract for a while, tried a cooler all-grain brew once and knew I wanted to add some control (or so I thought). I've now...
