Yesterday was stark proof just how fucking stupid my eRig is ...
Yesterday's batch was way more hand's off than when I use my automated system ...
The introduction of a pump, indoors, adds a real risk of flooding that's kitchen-threatening ...
My 1st pass at the Golden Stout was a perfect example - if the grain bed tightens up and divides the upper and lower areas of the kettle from one another, your pump will overflow the mash tun and flood your kitchen ... very quickly, I might add ...
The eRig has an alarm on the PID-controller ... it's loud ... so when something triggers it, you can't ignore it ...
The one advantage of the eRig/pump setup is the plate chiller ... the plate chiller is definitely more efficacious than the immersion chiller ...
Now ... let's talk about yesterday's rig and process ... and cost ...
The Sansaire makes perfect strike water, and it'll hold it at temp without you needing to be there indefinitely ... that's liberating ...
I checked it with the probe of the iGrill, 1) to see how close they would read, and 2) so that I could have monitoring on my iPad over at my desk ...
With no spigots, tubes, or pumps ... I walked away ... nothing could go wrong ... I felt free ... I was free ...
I could have let the strike water sit indefinitely until I was ready, too, which is perfect for brewing while working ... more on this in a bit ...
Since the BIAB bag is a great way to separate the powder from the milled grains after milling, and I saw first hand what happens when you don't do this last weekend, I used the BIAB for the grain bill, and popped it in the aluminum basket I bought on Amazon for next to nothing ...
That aluminum basket keeps the bag off the bottom of the pot, but like 1/4" or so, enough to keep it from scorching or ripping or whatever, and the hand of the basket makes it really easy to lift the basket up and down, kind of pumping the water around inside the mash tun, for when you are heating it up after it's started to cool off power ...
The thing is, there was no reason to have turned off the burner ...
With almost 3.5 gallons of liquid and twice that many pounds of grains in the pot, the range needs to be on like a power level of 4 or 5 just to maintain mash temp ... next time I just won't turn it off at all, and the iGrill probe gives me an idea what the temp of the mash is the whole time, and the alarms for going outside of the window notifiy me if I need to do something drastic ...
Again, walked away to my desk ... out of the kitchen ... at my desk ... worked a little while brewing, even ...
I wouldn't both with using the inner pot of my double-boiler kettle next time, and pouring through the grains into the bigger one ... that was a PITA because of the lack of height above the kettle, under the hood ...
Next time I'll heat the strike water in the boil kettle, on the stove, in position using the Sansaire, and then remove the replace the Sansaire with the grain basket and turn the burner on to 4 and walk away with the iPad to monitor the mash temp ...
After mashing out, it's business as usual, except it's better ... the 240v gets to boil faster than the 120v coil, boils harder, and the hood does a better job of removing the steam ... it's also nice that the kitchen sink across the room is free and clear, without the pump and kettle over there ...
Once the boil is started and the bittering hops are in, there's no reason to hang around until it's time to add more hops ... walked away from the eRig, walked away from the kettle on the stove ...
It boils, it's on high, and there's nothing to change until it's done ... free to work ...
I used a stainless steel ruler to measure my wort height in the pot, to have a good idea where my volumes were through the process ...
It's not hard to remember to toss the immersion chiller in the pot when you are adding the Whirfloc and the nutrient, and it's hand's off when it's in there ... again, no reason to hang out ...
When it was done, I killed the burner, transferred the pot to the sink, screwed the chillers onto the faucet and turned it on, and put the lid over the pot to limit what fell from the air into it ...
There's nothing to do ... the ground water is hot again ... walk away and let it go for a while ...
I came back, dumped a bag of ice around the base of the kettle to get a little bit more cowbell in terms of cooling, and walked away ...
When the ice melted, I poured it through a filtering funnel into a fermenter, capped it off, and threw it in a 40F freezer for a few hours to bring it lower ...
The compressor in a little chest freezer is puny, and when you put a heavy glass fermenter in there will a load of warm liquid, you aren't cooling fast in there ... again, walked away ...
Which brings me to the yeast ...
Happy with that process, too, as I really like the extended storage and reliability of dried yeast ...
Liquid yeast have been iffy for me, and dried yeast have been money ...
I thought that process was really easy ...
I StarSan'd a 600mL low form pyrex, then rinsed the StarSan with boiling water from my Zojirushi, and poured in a 400mL can of Fast Pitch ...
I aerated the shit out of the Fast Pitch with a milk frother, and then rehydrated the dried yeast in 5 seconds with the same, and covered it ...
The only improvement to that process for next time would be a drop of Fermcap S ...
Those yeasties were krausening in there by the time I pitched them after some hours ... next time I'll not get them going until I start to chill my wort, and I'll let them get happy while the fermenter is in the chamber cooling off further ...
If I didn't brew so many big beers, I'd just grab a portion of the actual wort to rehydrate them in, and skip the Fast Pitch ...
At the end of the day, it was a better experience than using the eRig ...
And the charting from the iGrill and stuff was a nice add ...
I didn't really find the electronic refractometer to be all that exciting, truth be told, but I didn't buy it for that ... I bought it for it's range, up to 85P, because I've brewed beers bigger than the manual refractometer read (Mulberara), and will again ...
I'm pretty happy with how things went, and honestly, with a few tweaks, I'll probably just do it that way inside going forward ...
Fuck the eRig ... and especially fuck pumps indoors ...
Maybe I'll sell that fucker on HBT ... the only thing I missed was the plate chiller, and not really ...
