I ran the above commands, but the install failed due to lack of space. This is a recent (sometime this past spring) clean install, and I ran sudo apt-get clean, so I'm not sure what else there is to cleanup. $ df -h Filesystem Size Used Avail Use% Mounted on /dev/root 6.9G 5.9G...

No grenade intended. Not advocating LODO or anything else. Just trying to understand the science.

Thank you for your thoughtful replies. I get that boiling wort/water has essentially zero dissolved oxygen, but dissolved oxygen is just an oxidation reaction waiting to happen. The fundamental issue (as I understand it, at least) is that oxidation reactions occur at a much higher rate at high...

Has anyone considered the effectiveness of a steam condenser for reducing oxygen uptake during the boil? I ask because I was recently visiting the De Halve Maan brewery in Bruges, Belgium and their boil was extremely vigorous, to say the least. I initially thought this surprising since many...

His math is right. White Labs claims 2.15 billion cells per ml. So 7 ml of yeast is 15 billion cells. After a 10X step up he has 150 billion cells. This is enough healthy yeast for a 5 gallon batch of ~1.050 of wort (for an ale yeast).

RO is perfect for yeast starters made with DME. DME is just wort that has had (pure) water evaporated away. No need to add any additional salts; they are already in the DME. Also, I second using RO for drinking, making coffee, and making ice cubes.

Problem solved. Predictably, the problem was out-of-date documentation. The instructions for installing tiltbridge using esptool.py don't match the partition table in 4mb_no_ota.csv; the SPIFFS binary should be downloaded to 0x330000. Once I fixed that, everything works fine.

Attempting to flash using web.brewflasher.com gives the following error: Installation failed Failed to initialize. Try resetting your device or holding the BOOT button while clicking INSTALL. esptool can talk to the device (and underlies brew flasher, as I understand it) but something is either...

Thanks. Doesn't work in Safari. Reading the logs works in Chrome. Downloading doesn't. Log is somewhat more readable: -^R:^F[^P^OlL^X^PE (640) esp_core_dump_flash: No core duѥѥfound! E (640) esp_core_dump_flash: No core dump partition found! E (31) SPIFFS: mount failed, -10025 ets Jul 29...

Thanks, but that doesn't work on a Mac. I tried the Brewflasher app first and it failed with no meaningful error message. I also tried flashing it from Fermentrack on my Raspberry Pi, with similar (negative) results. I was able to flash it with esptool (at least it claimed success), but clearly...

OK, I was a programmer back in the early 80s and can read C code well enough to see that when the http server can't find a file it redirects to "404.htm", which it also can't find. Safari is wise enough to terminate the infinite loop and give the (minimally) helpful message. I'm guessing this...

I got the tiltbridge firmware installed using esptool.py on my ESP32 and got it attached to my local network. However, Fermentrack was unable to connect and when I try to access http://tiltbridge.local I get 'too many redirects trying to open "tiltbridge.local/404/"' Any ideas of how to...

I have quite a few Inkbird products. Would love to test this one in my basement brewery.

Heat sanitation is the way to go for aeration stones. It is the only way to sanitize something you can’t clean completely. You just need to get it above pasteurization temperature for the appropriate time. If you are using a wand, just stick it in the kettle for the last five minutes of the...

+1 to boiling in a pot. I cracked an e-flask on my gas range a while back. Never again. I also put my pot on a kitchen scale, tare it, then weigh the DME in the pot. Minimum mess. I add a couple of liters of RO (by eye) and boil it. I usually set it on low and ignore it until it boils. It...

Do you also have the Spike neoprene jacket for your CF10? Does this cooling jacket fit under it? Which pump are you using with your glycol chiller? Why is it necessary to slow down the glycol flow? Thanks, this is super interesting.

Silicon is very oxygen permeable, which is not a good match for a fermenter. I use EPDM gaskets, which are much less permeable.

I love my CF10. It will do everything you want and more. Will bust your budget, but I think you would not regret the decision.

I have not (yet) purchased a microscope, but I found the following page very educational Link.

When you cold crash beer in a fixed volume, sealed fermenter, there are two effects that reduce the headspace pressure. The first, contraction of the beer as it cools, is actually a very small effect: for 5.5 gallons of beer the shrinkage will be only a little over an ounce when crashing from...
