I got this vibe from fridge. One of the reasons I often put some frozen hornets in those, no packaging. Deters people from doing stupid things.

Nah, top left is totally one of them hardcore STEM ladies from Uruguay

They are awful for cooking, believe me, I have a home lab.

Induction hobs are great for lab though, except for glass vessels, of course.

I had this story when we've picked peaches on pick-your-own farm near Dallas, to make melomel (turned out awesome), and while we were busy, some flies ate skin on our ankles, that took almost a year to heal. Now we moved to Finland and some similar gnats are trying to eat all the skin, this season starts now. Well, skin adopts and learns to heal faster.

There was another pick your own farm in Arkansas, we went there for strawberries (to - you guess it, make melomel!) And when we told the farmer what we are up to, he was like "that's cool, but you know, be careful telling this to people. You know, this is baptist country" - which made us make jokes about baptist spray. We had a barrel of mead at the end of first stage of fermentation to throw berries in right away reducing contaminant growth time and made sure we leave before a local school kids arrive to pick more berries. Good times. In the morning the fog was so heavy, I detuned radio and pretended it's Silent Hill.

But there is another story I heard from a friend. Her granddad retired after a career of chemical factory boss. So he bought a hectare of land and decided to grow black currants. You can take chem engineer out of factory, but... He got hundreds of bushes, and assigned them to family members. They had KPI, deadlines, whole deal turned into awful grind with corporate stench. And what would one do with some cubic meters of rapidly decaying berries anyway? They ate it, canned it, made wine (not very good one), needless to say, nobody in the family could stand black currants anymore. How did this surface? I took her bf to get some beer for the party in store and there was this single blackcurrant ipa. I was like - here, she'll like it, it's sure bet. Well, it wasn't, lol.

I was just thinking of caramelizing very small fraction of honey for flavor this year out of curiosity, but with my small production it will have to be good honey probably, I'm not at scale where waste appears yet. Although there is a risk to suddenly inhetit an empire from my neighbor.

Could be, the world is wide, though, and I'll wait till we have more knowledge about it to place a name. Which does not stop me from culinary experimentation!

There is no "expired", only "improperly fermented". Sure, it could be very bad, but then you should've paid attention to it in advance, respect the nutrient and all living things who brought it about.

Do you know you can actually buy predatory mites and nematodes to enjoy your aphids? This is what worked in my situation somewhat, although it does not help if the plant is already heavily afflicted. These guys sure will not fly away.

long low narrow planter along the front

had this balcony setup just on the sea coast in Finland, not much benefit. In the end, terrace shelves against the wall and planters on the floor are different only in aesthetics. Just had a lot of plants and birds - make sure you have some attractors to those (scatter some food, leave nest building material, place a cat behind the window to be mocked) - still lost plants quite often to elements and larvae.

A fellow beekeeper!

Bochet

TIL proper name for that thing when someone new to the art is being told to "boil your honey really well or mead will spoil"!

How are things done there on the other side of the world? Do you move your bees to fields with these flowers, or is it just arbitrary seasonal labeling that does not really mean you are really collecting that flower dominantly?

Would you want to try my bee sensors that listen to the bees every hour?

We've got tired of just fermenting standard wort with different yeast strains for comparison, and we are starting full-sized batches of proper styled beer split and inoculated with very similar yet distinct yeast from the same class. The first in line are Belgian wits. Weather permitting it'll be outdoor brews! Hopefully this would be fun experience, will try to post inspirational results here.

And spruce tips are coming soon as well, but not yet. There is ground elder everywhere, but I'm reluctant to give it a try in brewing, need to learn to ferment it with lactic first and see if it is any good to my taste.

Yesterday we've tasted small batches of... some weird yeast caught in some local beer in UK bar, it certainly looks right under microscope, counts to proper population with more or less typical dynamics... and then fails to change the gravity, yet produces quite distinct flavor. 1040 OG beer starters end up too sweet and disgusting, of course, so we've tried instead kombucha-style mix of pale wort and tea, to 1010 OG, sterile, of course. The gravity did not change again, but the flavor! It was not quite like kombucha, but along the lines, and definitely the tea flavor was more distinct that in reference non-inoculated sample, that tasted disgustingly sweet and stale. And somehow this "monoculture combucha" hits in the head. What a weird mutant. Something to research now. Maybe we have a 0% beer magic in our hands?

Just old farts being naturally (not without covid help though) replaced with people with demand for future, I wish brexit voting was delayed.

 

This time of year one thing happens that has absolutely no relation to holidays: late berries (cranberries, lingonberries, rowan) spent enough time in frozen state to develop flavor worth of melomels. A gift for self in several years, something to be safely forgotten until bottling and then again.

Of course, I've kept those in freezer, as I don't want to fight all the birds for rowans (note: they still had plenty, I'm not greedy) and I'm not that good at digging frozen forest floor for the rest.

 

I've been doing homebrewing together with my wife for quite some time, and at some point we started collecting a yeast library. There was a point in my life where we had an opportunity to start a company that does something we enjoy; we've tried starting an analytic lab for microbreweries (as we are both actually doctors in chemistry), but it didn't take off at all due to lack of demand (and COVID breakout), we had to switch to doing whatever brings cash (of course IT stuff it was, mostly, I feel ashamed).

But yeast library kept growing. We've decided to give it another try, got permissions from the Big Brother, and rolled out a small production!

We've deployed a webshop at https://store.zymologia.fi/ , there is other stuff that's kind of a byproducts of whatever other things we've had to do to get along (some of it was and is fun after all). The idea is that I don't think it makes sense to scale it up any further, we just have proper but minimalist equipment to do sterile pure culture cultivation, not large tanks, only glass that could be properly washed and autoclaved, and full-grain growth media because I hate smell of extract (and proper preparation of wort is about as difficult as getting extract clear enough for yeast making). Anyway, it's an actual commercial operation, I'm curious to see how far we can go with such attitude and whether it would become profitable or just another "make the world a bit happier place".

Most of yeast on sale is listed as "not available" which means we'll just have to wake them up, feed them up to speed, and package, which takes up to 2 weeks, which is less than beer recipe planning and preparation phase, at least for me. I don't think keeping an inventory with live yeast is a good idea anyway - many times I've had sad starved liquid yeast fished out of fridges in stores only to see lags on 30+ hours. That's also why I'm reluctant to go to resalers, though I might try it.

What I really think should be happening is yeast exchange. I don't want to keep things any more commercial than the general Finnish anti-soviet spirit tells me, so let me propose this idea: yeast growth takes time and effort, but sharing is caring - I'd be happy to share a swab of yeast culture with anyone who comes to our place (just tell me when, of course most of the time there is only yeast in the lab) with their own sterile slant carrier - I won't be shipping these, for I'm absolutely certain delivery services will mess it up, and also I (or whoever would be hanging around at that time) won't get to have a chat with you. (Please do this if you know what you are doing though, storing culture and scaling it to a starter is a bit more complicated than just making a starter, mistakes multiply badly with exponential growth and it's not very feasible to propagate without going through single-cell plating or something similar. If you don't know what that means, learn it first, or it's worth just buying a ready liquid yeast, the great purpose of sharing culture material is to let other people have it in their library, which would require you to go through single-cell propagation at least a few times a year).

We also have an opensource (all we do is opensource, I believe in the idea) piece of software to keep yeast lineage in check here: https://github.com/Alzymologist/yeast It's a bit underdocumented at the moment to say the least, but it uses Bayesian inference to analyze yeast parameters and catch mutations, and it was able to detect deviations before we've tasted the outliers blindly, I think it's quite cool too. I don't think anybody did this before.

Sorry for self-advertisement, I've asked moders if this sort of thing is OK here before posting. I hope this is interesting enough to be worth being here.
