SO I wanted to weigh in here as I have used my new 20 gallon BME during my last 2 brew days. At the moment I am not sure where I stand on this thing.
First off, my first batch which I made about 2 weeks ago, had to be dumped. I have brewed about 10 times and never dumped a batch with my old kettle. The beer was disgusting. I am thinking its possibly from not doing a full soak and clean (I just rinsed it down thinking it was new so it was clean). I am hearing that sometimes these kettles have left over oils from the production process, so I am really hoping that was the case. Since then I soaked it in PBW and and scrubbed it down with barkeepers friend. I soaked all valves, thermometer etc.
If it was not from that, then it was from the real big issue. Either this is NOT holding temps during mash (I do full volume BIAB) or the thermometer is not accurate. Both brew days if going by the installed thermometer my mash temp has dropped significantly over the hour. My strike temp was 160, I added my 26 lb of grains and after the first 10 mins it was still showing 160-162. That does not make sense. So then when I checked about 10 mins later it was down to 150. Well thats where I wanted to be. I checked 5 mins later and it said 140! First batch I ended up adding flame to it to bring it back up and then it was showing 160 again even though i flamed out at 150.
My second brew day instead I got another thermometer that I used with 10 gallon kettle, its just one of those ones you stick in the wort. It was showing 154 degrees when the kettle was reading 140. So I left it alone, checked a little later, in kettle was still showing 154, installed thermometer 140. So i left it alone, it held at that temp throughout the mash and i went about my business.
The thing is the rest of the time when I compared the 2 thermometers once I restarted the flame and got up to boil they would be in sync. Even on the cool down they were in sync. But they were VERY off for the mash process.
So I dont know what to think. 2 potential issues: 1 it may or may not hold mash temp. 2. it may or may not give an accurate temp reading.
I will see how this batch ends up.
Other than that, I mean build quality looks really good, I like that it is oversized at 24 gallons. I like the etched markings and all the ports. I dont like that its very hard to read the thermometer due to its low mounting point. You also have to be VERY careful wrapping this when holding mash is the bottom with the vents its extremely hot. The first week when I wrapped it, the wrap actually melted and caught on fire due to the heat.
So overall not in love with this thing. I had to dump a very expensive 10 gallon batch of beer my first go round (possible user error) and this batch I dont know what to expect due to temperature variances.
