This is a handy tool. Scroll down to the "Can I Mash It?" calculator.

I use one in almost every batch and like the info it provides. I don't trust the absolute reading the Tilt provides, as usually there's krausen caked on it throwing the reading off. If I want an accurate reading a hydrometer is still my go-to. However it is nice to see the rate of change of...

Some Kolsch yeasts will slow down fermentation then finish out, a bit more time in the fermenter may have dropped the FG some more. 1.028 seems more like an incomplete fermentation rather than a problem with a grain bill. Can you post that? Also, what was your mash temp? The ABV adjustment...

An RTD is a resistor that changes resistivity with temperature, it takes a given voltage and runs it through the resistor and the output voltage (analog) is proportional to the temperature. The ds18b20 looks like a digital output in which a microcontroller reads and converts the 0's and 1's to...

Looks great, thanks for the opportunity!

If you have access to a thermal imager you'll be able to see where the coils are without a pilot hole.

What yeast did you use? Looks more like krausen that hasn't dropped than an infection to me, however they can be misleading. It may have trapped enough bubbles so stay afloat. Can you cold crash it? I suspect it will drop out. *Edit* Even if it is infected it's still safely drinkable, just...

Alpha amalyse prefers a higher temperature than fermentation temperature for conversion. It will still happen, just takes longer (not sure how long however).

Have a 3-roller and have been happy with it. I used to use a corded drill (it would get pretty hot at the end of milling) to mill but converted to a dedicated motor/gearbox which proved to be a great investment.

Either way will finish it out nicely. Carbonation will change the flavor quite a bit so I wouldn't worry too much about the flavor now. Personally, I'd bottle and let it condition there.

I can't speak on root beer flavoring settling, but you'd have no issues adding the flavoring in the keg after carbonation. Slowly release the pressure from the keg, open it up and add flavoring, close it up and purge the headspace with CO2. Once purged and pressurized at serving pressure you...

I've been very pleased with this one. I mash/boil in the same vessel and it sits on this scale so I know exact volume all the time. Use it for closed transfers, weighing grains, etc. Its had very little drift in the measurement (.2 lb over the entire brew day), and no "auto-off" which is very...

Should work well if our suspicions are correct, good luck! On your earlier post - correct, it would not be a difference of 25 points...a few at most.

Sure, the manufacturer states the thermometer is waterproof/submersible. Keep in mind, active fermentation inside the vessel can be ~10F warmer than ambient (if in open air, not sure what it would be if the carboy is partially submerged/covered with a wet shirt, etc.) Ideally, a thermowell...

Difference in temperature to cal temp of the hydrometer would account for a couple points, not ~30 points. Tough to say why it's stuck - you mention the thermometer's accuracy, could your mash temp have been higher than the 68C you mentioned? If it was hotter, some accelerated denaturing of...
