I brewed my first batch on my new BIAB rig, which is inspired by @Bobby_M's great work, but not designed by @Bobby_M (although he did make me some custom parts that I will post about later). More details on the rig below, but perhaps having gone a little too far down the low-oxygen rabbit hole...

You could mix up a batch of OneStep in your tank. It’s a no rinse cleaner with “sanitizing properties”. It is not a registered sanitizer, so the health department won’t be satisfied, but it should prevent a beer flu superspreader event. I would be a little concerned about people drinking...

If the concern is O2 pickup during mash recirculation, you would be better off replacing the silicone hoses with Tygon-A-60-F or Tygon-A-60-F-IB (fiber reinforced for higher pressure). The permeability of silicone is ~30 times greater than Tygon-A-60-F (6.2*10^-8 vs 2*10^-9). Does it matter...

These pressure sensor’s stated accuracy is +/- 2% full scale, so for the 30psi model that is +/- 0.6psi. Reading beyond the tenth’s place will not give you any more accuracy. You should look at the Honeywell sensors, like the hscmand015pa2a3, which has an accuracy of 0.25% full range. This one...

OK, feel free to ignore this, but I spent a few minutes hacking together a way to make randomizing cups relatively painless for four unique beers and one duplicate pour. (OK, I actually spent much more than a few minutes, since my Python skills are not very good and my Latex skills have...

I’m interested. I have a CO2 meter, but tracking the other air quality factors is very appealing.

Interesting experiment. I would recommend giving each taster five (or six) pours: one of each with one (or two) randomly selected duplicate pour(s), all randomly labeled (i.e., so my "beer #1" has a <=20% random chance of being the same as your "beer #1"). Then conduct the trial in three...

The Romans used a “thick layer of olive oil” to protect their wine when they shipped it in clay amphorae, according to several google sources. It should work with beer, but it might not be cost-effective at the carboy scale and modern olive oil prices. Oil also has very negative head retention...

You should consider buying a DrinkMate Omnifizz. It’s similar to a sodastream, but allows you to carbonate other beverages than water (because you can wash the nozzle). No shaking required. It uses the blue soda steam co2 cartridges, but there are various 3rd party adapters to connect to your...

Maybe a licensed electrician can chime in, but I recall enough of my 40+ year old EE (and mostly CS) undergrad to know that AC power is much more complicated than the DC power equations @doug293cz is using above. In a purely resistive system, the equations hold for AC (using RMS voltage and...

Merriam-Webster still defines grok as: to understand profoundly and intuitively

I’ve used those on the gas grills at a vacation condo; they work well for saving fuel when people forget to turn off the grill. But I’m not sure I would trust them to more than +/- 5 minutes accuracy without some testing and calibration. How are you thinking of using it?

Check out the podcasts in the first couple of posts. Most of the zinc in the boil is bound up with proteins et al. Adding zinc to the fermentation gets it where it needs to be.

Very timely post. Craft Beer and Brewing has a recent episode on fermentation health, with a deep dive on zinc at around the 21 minute mark link. I thought it was fascinating. My main take aways: * Cold side zinc addition is better, as studies show that 60% of hot side zinc is bound up in trub...

Could you add links, at least to the chiller?

I had not heard that oats helps with yeast health. Do you have a reference for this statement?

Summer Haze. <To be read out loud with an exaggerated Scottish accent at a Scottish themed outdoor event> Summer Haze is a New Scottish I.P.A. This Brew is intended to evoke memories of glorious days of summers past and summers yet to come. Summer Haze is brewed with the finest Golden Promise...

The Presto canners are rated for 12,000 BTUs, which is more than many home ranges put out but less than some "commercial style" ranges (e.g., Viking).

What size E-flask do you use? Is Fermcap enough to keep a 5L starter from overflowing a 5L E-flask? If you use a 6L E-flask, where did you get it? These can be very expensive.

Most 10 barrel conical fermenters have 6'+ of beer above the dump valve, which translates to at least 2.5 PSI. A CF10 has about 24" of beer above the dump valve (depending on valve placement) so less than 1 PSI. I suspect that, plus market differentiation, explains the difference. I personally...
