Or using a population that's already viable.
Which, from commercial yeast sources, doesn't exist. Any process meant to store & ship yeasts negatively impacts their health & viability; hence why starters (& rehydration for dried yeast) is so important.
Yes. Are you trying to HELP me talk beginners out of a doing starter?
No, I was pointing out the stupidity of your claim that we need to somehow ask the yeast how they are doing before deciding whether to do a starter or not.
Could you list the lab equipment necessary so that beginners can jump on amazon and grab some Chinese b-stock?
Of course, to make your "point", you had to clip the rest of my statement wherein I outlined why such capacities are completely unnecessary for either the new, or experience brewer. Why is it you have to distort what I wrote to make your "points"? As was mentioned in my post - before you dishonestly deleted the section that was inconvenient to you - all of these numbers have been calculated before, there is no need for brewers of any stripe (except, perhaps, the anal-retentive ones) to do yeast counts.
But, to actually answer your question (instead of dishonestly editing it so I can reply with something unrelated), all you need is a hemocytometer & toy microscope - cost is ~$50, new, and that's with a USB-connected microscope...
I'm not sure which base you think I'm on.
The one where you are advocating a position that starters are not worthwhile for the beginner due to some sort of imaginary unpredictability of yeast, imaginary complexity of starters, and imaginary incompetence of new brewers.
How about a categorical error? Before the rest of your perfect Thanksgiving dinner recipe story, I should point out that your average beginner does NOT have a laboratory. They have a kitchen, and hopefully a measuring cup. The predictability of microorganisms or anything else in nature isn't much help if you have poor accuracy, or are unsure enough of what you are doing.
You really need to read what was written; the whole point of my "story" was that you do not need laboratory equipment to achieve a reasonably accurate estimate of yeast numbers post-starter. Simply knowing nothing more than your media composition (e.g. 1.040 DME) and a rough idea of starting numbers is sufficient - both at home, and in a real lab. All we need in a lab to get the cell numbers we require is media of a known OG & a rough (within a factor of 10) idea of the number of cells we add at the beginning.
The home brewer, in their kitchen, knows those values to within the accuracy required, without the need for any specialized equipment beyond a scale. That is all it takes - a measly $5 kitchen scale - to achieve the exact same degree of control and predictability in your kitchen that I achieve in my lab. In other words, if you can operate a scale, boil water, and read viability info off the side of your tube of yeast, you can be as accurate
in your kitchen as I can be
in my lab.
That's really amazing. How does that clarify things for the beginner?
I have a story about scientists too. "When I asked him, my microbiologist friend told me, that if I couldn't get an air pump, I should shake the carboy for a few minutes every day because yeast like oxygen!..." Why don't you just ask the guy that monitors a fractionating tower at a refinery how to make whiskey? (actually that guy probably does make whiskey) Whatever. I think I've made my point.
I don't think you made a point there; unless your point was to make make some sort of snide side-remark attempting to dismiss my expertise in an area in which you are clearly ignorant. As for your new question, teaching a beginner about proper pitching rates and how to achieve them does a number of things:
1) Its never too early to lean about best practices; even if you are not immediately capable of implementing them.
2) Starters are an extremely simple thing to do, well within the capabilities of most new brewers
3) Starters provide a new (or old) brewer with an easy and cheap approach to improve the quality of their beer.
4) Informing a new brewer of the role of proper yeast numbers & health sets them up for success by informing them of a common cause of bad-tasting beer and provides them with a procedure to avoid it.
As someone who has <indirectly> claimed to be a teacher, you should recognize that as the de facto standard of good pedagogy for self-directed learning.
I'd also point out that comfort levels vary greatly between people. I'v known brewers whose first brews were all-grain, complete with yeast starter, and were successful. I've known others who brewed extract kits for a prolonged time in order to build their confidence. Most new brewers fall in-between. Your approach is to assume that all beginners are incompetent and incapable of handling a rather pedestrian task. It is an unrealistic position, underestimates many new brewers, and is also quite insulting to the majority of new brewers to whom starters are well within their capacity & comfort zone. Again, as someone claiming to be a teacher you should be well aware of asynchronous learning and how you as a teacher set up all students for success given different their learning capacities...
Well, I'm not sure you understood my earlier posts. I'm not sure we have the same goal(s). I'm telling beginners not to screw around with starters if they can get reasonably fresh yeast.
Which is, generally speaking, bad advice. Hence the push-back you are receiving. Viability is not the sole factor in yeast quality - yeast health is also key. Packaged yeast, even when fresh from the company, is generally of poor health. Anoxic, nutrient-void environments are not friendly towards yeast health. Nor is being dehydrated. Reaching appropriate pitching numbers by pitching multiple vials of yeast is still inferior (in terms of yeast health, off-flavour production, attenuation, fermentation speed, etc) than yeast from a starter. It is also significantly more expensive, and is a bad brewing practice. You're essentially arguing that new brewers get into bad habits that they will later have to break, rather than doing it correctly (or at least being aware of how to do it correctly) from the beginning.
They have enough to worry about already, and generally worry too much as it is. What's your message? If you have a laboratory it's trivial. If you don't, don't worry! The people that make the yeast know what they are doing-- BUT DO A STARTER!
My message is simple and concise - proper pitching of healthy yeast is the easiest thing a new brewer can do to maximize the quality of their beers. Achieving this is simple, cheap, does not require one iota of specialized equipment, and is well within the capacity of the majority of new brewers. Hell,
I even have a blog post & video showing them how to do it.
I don't get it. I don't get yeast fetishism. Some one else can accuse me of not caring about pitching rates AT ALL, now. Maybe if I explain it again it will finally sink in that the exact opposite is the case.
Given that yeast are (sours aside) the sole source of fermentation in the beer, a major source of both flavours and off flavours, and are the one ingredient whose quality & activity the brewer actually controls, their health & activity should be the foremost concern to every brewer of every skill level. Good yeast can turn a bad brewday into a passable beer. Bad yeast can turn a perfect brew-day into an unpalatable beer. Learning to properly manage yeast is the single most important, and by far simplest, thing a brewer can do to improve the product they produce.
Hence the "fetish".
