  • Large amount of any chemical pufiried, concentrated, and spilled in one place is a disaster

    Improper utilization of any energy storage media - wood, electricity, even gyro-storage - is dangerous and produces hazardous waste

    It’s all about being technological and playing fair. There is nothing that switch from one energy storage to another would accomplish in terms of environmental safety.

    I love NH3 idea, it’s IMO 3rd best solution. Second best is alcohol. First best is making your energy locally with whatever you have and not wasting it for stupid things.

    But all this will be easily messed up by reckless greedy maniacs that have most of the power in the world right now.

    Here is something my dear friend wrote I just read yesterday: https://alexshvartsman.com/2024/12/03/the-rattler-by-leonid-kaganov/



  • But, as far as I remember, major contributor to carbon emissions are not poor villages, but jet sets and their factories in poor villages exploiting the work of poor villagers who have no say about their air quality lest they lose their jobs like they lost their means to sustain themselves from farming. Indeed, just not flying for fun and not selling the oil and coal that do not really belong to them would be so much more technological than trying to get grants for things they do not understand (and waste them traveling the world on planes telling everyone they should invest in it too only to then burn the rest in taxes used to support oilgascoal industry directly or not). When you show perpetum mobile here it is totally relevant - that’s how greenwashing works in terms of economy on every level, no matter what technology is being praised.

    That’s essentially how many gases are made from mixtures, like notrogen or oxygen. Showing this as something new tells a lot about author’s uderstanding. Carbon capture is not about making entirely new tech, it’s optimization, and that’s where startups suck at everything except for getting and then wasting cash.



  • Malting it for base malt is probably not worth the effort indeed (kind of weird that there are a few small-scale enterprises around where I live who try to make small batches of malt - and it’s base malt. Of course it’s inferior to large scale, sadly, I had sad experience trying to use super-local. Why don’t they see the real market potential for weird stuff? Maybe I should take that space when I set the process?), but there are limitless potential specialty varieties you can try. Roast it differently? Skip toasting altogether and use it asap to see what happens? Reproduce some historical process? So much fun (probably).



  • I have similar situation (but right now I have ~20 kg of oats, there are other stuffs around too, I just happened to take oats), so I’m trying to build some decent malting equipment. Unfortunately, doing it outdoors in winter is sad enterprise, but I’m totally just giving it a try when I can! (Doing it indoors would be either stinky or loud, and I already have too many microbiological stuff going in same space) I do not believe I’ll lose much except for conversion rate and sugar content, but might discover some new flavor tones. When I’m done, I’ll be posting here and trying to share the product.

    So I urge you to do the same!

    There is no reason to expect that something will not ferment well just because it was not purebred for brewing. Even random yeasts mostly yield good results. Well, yeast is much more definitive in final profile and you CAN screw up by using some really stinky or low fermenting yeast. Grain, on the other hand, is just yeast food and grain flavour mostly (yes, there are other things to fine tune, but first order approximations is what we should care about in experimentation). Does it smell and taste good? Then go for it!






  • Well, it’s bad news, all those super-processed products almost always are treated with metabisulfite or something close enough, and only wine and a few other products require it to be listed on the label. It’s pretty much treated as part of detergent for washing fruits. Completely unjustified as product is sterilized later in turning it into extract, but it is simpler to keep buying this historically accepted mild bleach and treating all fruits with it anyway. Maybe increases their storage time in shipping pipeline. Something I do not wish to think about in great detail, for my first lab in Finland was in a rented fruit storage bunker and I washed it and dismantled control equipment myself. Could have been WW2 nazi camp facility for what it was worth.


  • In my childhood, we had these kinds of root vegetables sliced and caved in on one end, and a spoonful of honey was placed on top and in the cavity. Somehow this sped up conversion to overnight, and it was a treat. I guess, similar process could be used to convert them for brewing.

    Although the whole idea sounds a bit like potato for vodka. Nothing wrong with that too, but the flavor might me less than interesting in the end. Worth trying I guess. I wish I had some of those now, not unripe ones from the store.



  • Steamings damage corks, especially sterilizing ones. Their number should be minimized. Now for bottling, I do not think it is important for corks to be sterile, as anything worth of corking will kill whatever might be living on cork surface. Sanitized is enough.

    Now repackaging is another beast. Once packaged, corks are left for indefinite time, and if inoculated with something that might survive on bare cork (pretty much this means fungi), it might become a nice growth media. Then, steaming might kill it (and if it is not pressurized, that would not kill spores), but it will not clean it from the cork.

    So, on small scale, it is not very important, some corks might get spoiled occasionally. But 6000 is no small scale lol.
