Dead yeast is not a waste though, you can use it as yeast nutrients :D

Waste not, want not. If nothing else, it goes into the compost, as does my trub after drying out.

Yeast are surprisingly resilient. I had a sourdough starter I forgot in my fridge for months and it was dry and rock solid. I chipped off some pieces, added more water and flour then a couple days later it was bubbling away. As long as there a few live cells, you can bring them back with a little work.

I just ran a barrel of sugarwash. But the wine red star I use was old and close to dead. It looked almost as bad as Jessie's mystery yeast. So I made a nutrient solution and did 3 generations of yeast starter. I dumped the results into the mash each time. It took a month to ferment out at 8% but it worked and now I have a batch of yeast that's viable for next time. And it's been bred to be more compatible with a sugar wash. In the end I was amazed that a sugar wash turned out tasting like a fruit wine. It's got to be a combo of the keylime i use for the wash and the yeast. It's so good I'm going to keep a gallon and use it as a base for a fruit wine. Maybe put some lilikoi concentrate in there.

No 3 should be the best as the dead yeast acts as nutrient for the active cells during fermentation. I will personally use that.

They are not eating anything, except maybe for each other. It's just a rehydration test to see if they are alive. Yes they will all die soon without nutrients. But that's not the point of the test

Jesse, here is a pondre, your opinion would be appreciated. So I like spirits, I'm okay with white rum. I like spiced rum. Brandy, vodka, gin is one of my favorites with all of these things about the same proof. Don't really get why I don't like whiskey or bourbon as much as the others, even though in the rum you can certainly taste the barrel age, that being said, I will reach for that little tiny sample bottle of single malt highland Scotch and I like it better than any whiskey and the bourbons I've tried, maybe I need to buy more expensive ones. So what am I missing here? I would like to distill my own spirits, which 3 would you recommend try to make for someone that has a (finicky) taste?

Depends on why you're using it and what exactly you're looking for TBH 🤔 If you're just looking to do some simple quantitative analysis 🥼 Like doing true viability testing by live cell counts, a minimum of 800x with an NA value of at least 0.8 will do 🧪 But if you're actually looking for more qualitative analysis and interested in seeing more than fuzzy dark blobs, like maybe some bacterial contamination identification or something more complex like that... 🧫 It'll require something like a minimum of 1500x @ NA of 1.2+ w/ phase contrast condenser, if you really want to make those differentiating details visible 🔬 I'm looking at upgrading from the former to the latter as soon as I can afford it, microscopy and microbiology are awesome but certainly not cheap as hobbies once beyond the basic equipment 😅 Hopefully that helps answer your question sufficently and if you have any other questions please feel free to inquire anytime 💯😄 --🧿RuneShine, Michigan's Norse-Druid Alchemist🧪🥼🔬

They can last for many years if they are in the fridge. I've even had some ale yeasts that sat outside, in a bin, for 10 years. They needed some TLC but still were viable enough to make some beer

He covers that at around 05:00 ... if it's 2 years out of date when you buy it, that's "not ideal" but as long as it's close it should be fine. He's more concerned about how long the packet has been opened.

Yeah. You can keep the yeast from a previous batch and throw it in your new batch. If it's going to be a while between batches you might be better off getting new yeast.

@andrewdeming52857 ай бұрын
I’m not sure you’re showing anything other than how well different ages of different yeasts rehydrate. Too many variables and no actual test of viability. I wouldn’t mind seeing the same test with different ages of the same yeast. You absolutely need to add some sugar and see if they will ferment. The one you called dead may and fact be perfectly fine, but we’ll never know.
@AlasdairThompson7 ай бұрын
...but as we all know it's pretty much a linear relationship between how quickly they rehydrate and how viable they are. It's not a direct test but it's a very good indication.
