  • U-tube is just a glorified pendulum. But using this classical U shape for liquids is worth it. Pendulums is how you measure mass if gravity is too low.

    I know some people inverted U-tube and immersed piezo fork into liquid. Then they struggled with reflections and setting feedback right or making sweep practical enough. And then there is electrical connections going into the probe through liquid surface, which is another concern. Still, in batch process (and all brewing is batch process) immersible probe should be much faster and washable than flow-through, I guess.


  • Oh, got carried away and missed another question. I’m actually throwing all good quality stuff in melomels, there are no favorites really. Other than Vaccinium uliginosum (English words for berries are terribly misleading, used interchangeably for pretty much all berries of same color - so these are usually called “blueberries”, but that’s not what is called “blueberries” in USA, for example) berries that result in something that shames wine made of grapes - so much cheaper, literally grows in most unfarmable places, melomel tastes similarly but better, and no pretense about “grape locality” and “northern slope” - just good stuff, every time.

    Cranberries and lingonberries are kind of staple berries here, rowan is less known but also abundant and tastes great. Other hidden treasures I’ve found include hawthorn, ribes, and (very unexpectedly) hippophae. Now it’s time for imported citrus fruits (skins are best part for melomel) but I’m all out of started base mead (and almost out of space).


  • I used to buy directly from beekeepers (never from stores, that junk is just spoiled in most cases). Only from people you get to know personally, beekeepers are the most hardcore underground people around for some reason. They usually sell honey in meadmaking quantities much below retail. Just talk to people around, it’s abundant all over the world. And the result is totally worth it.

    I’ve been doing this for over 10 years now I think; had to move out of USA at some point and lose about 300L of product (it has to age, nothing you can do - and shipping alcohol is very complicated issue) - gave it away to friends, this was quite a challenge. Then started all over and over, the oldest bottles I have now are from 2019. The best time to make mead is 10 years ago, second best is now!

    Then, recently I became a beekeeper myself. Oh, this is addictive stuff. My beehives are smart homes now, I can listen to the sounds of bees and check their environment from home and I’m going to start selling the system to other beekeepers within weeks. And something like this happens to anyone who gets into beekeeping, it drives you crazy. I won’t be selling honey myself for some time though, as I’ve only started recently and all I get goes into mead I can produce myself until the families grow enough, who knows how long it will take?

    At least I’ve learned the ins and outs of the trade, why exactly honey from somebody you trust is completely different from retail anonymous “local honey” jar in store (or much worse, imported ones). There are quite objective shortcuts that should not be done but are economically attractive.


  • Refractometers are quite useful for pale wort and clear distillation products - or anything where you calibrate close to target phase subspace (honey, must, well-known beer recipe, etc.). I use mine to determine when fermentation rate slows down to determine termination in yeast tests - their relative readings are OK, if they aren’t changing, it’s worth considering density is stable.

    Regarding U-tube, that’s fun enough little project if done right. I had even more daring idea to build contactless (read through glass) density scanner, I even have the already soldered and flashed board and transceivers somewhere around the place. The prospect of quick reading density and inner fluid temperature without exposure seems attractive enough, but it’s a lot of research work to tune this tool concept, and then to turn it into comfortable product, and I’m kind of short of time-money invariant resource now.


  • Refractometers are no good at all, especially with THIS much colored stuff. Could get over 2x error, which is nonsense.

    After all, you don’t have to lose that stuff, if you had a tall and narrow plastic cylinder, that would fill that glass on the photo when you are done.

    I was thinking to design and build a U-tube density meter for regular people who can’t realistically spend a few thousands on proper tool, I can see those in slightly above decent refractometer price range (and that would indeed take small amount of sample, not as small as refractometer, but still). I wonder if I’d be able to sell enough to cover the expences (and myself I do have a ridiculously expensive and unnecessarily fancy MettlerToledo U tool in addition to all floaters and refractomters, remaining from good old times I was hoping to do paid analytics for microbreweries and thus needed something certified).



  • I don’t think this means anything, there are indeed many other benefits, including direct payments. This is small and probably some legacy, but still not a reason to stop counting money. Well, 50 Eur is not 0 Eur. There are plenty of small credits for taxes and they keep adding up, fortunately, all is well automated and done without lifting your bottom from PC effortlessly (I’ve filled US tax papers for 7 years and even went to IRS to complain, thank you very much). Typically people end up with 800 Eur or so without even doing anything special.

    That said, Vero just forgave me a few cents yesterday, they seem to drop taxes on certain transactions if they end up below 10 Eur or so - not worth the hassle, I guess, even electronically.
