  • Update: Yeah, dang, it doesn’t work as I expected.

    Observations: The lid bulges, but barely any movement of liquid happens. I had to press the lid really hard to get the slightest flow towards the can going at the beginning. It’s barely even trickling now that the line is filled with liquid. As this is going to be a rather light beer, I don’t expect much more CO2 buildup, so this really isn’t ideal.

    Theory: The buffer of air is too large. The CO2 from the fermentation increases the pressure in the system, but not beyond the compressibility of the gases involved. Applying pressure to the lid took a lot of force and felt like squeezing a large half inflated ball. Also, some of the CO2 may have dissolved in the StarSan solution.

    Now I hope I have not spoiled my beer by at least theoretically exposing it to all the oxygen from the headspace in the keg. I’ll probably get a bubbler ready tomorrow and just purge the keg with CO2 from a regular source.
    Most of this setup sets me right on track though to do a oxygen free transfer though, so not all was in vain - in case that I haven’t spoiled my brew. /o\

    The only possible fix that I can think of might be using a fermenter that is actually rated for pressure and doesn’t “inflate” like my plastic bucket, but I’m not sure how much that actually contributes. Brewing a bigger beer with more generated CO2 would probably also be advantageous.




  • The darker the roast, the lighter a bean should be. You could count a number of beans you have your numbers right and get decent results with, weigh them, and thus compare their roast to that of other beans. That way you‘d be able to find out if your achieved ratios are tied to the roast. Maybe you could even work out a scale telling you what to expect, a ballpark to get your ratio somewhat right when opening a new bag of beans.

    That said, I’m only citing theory here, don’t take what I say as the last word on anything :)



  • Not meaning to sound dismissive, but to me, most “apply 3D printing to $x” pieces, this one included, sound like looking for problems for a solution, not the other way around. Just look at how many “holders” people make with 3D printers.

    That said, I’m not against the technology and I’m having an eye on the market myself. Also, I enjoyed the video. Great creativity, and I like the BruShow in general: The guy seems so damned friendly and while being well produced, his videos don’t put their production value before the actual content.
