I agree with you there a little Jamil, but my testing comes in the form of tasting the starter wort prior to the final build up, im happy enough with my taste and smell technique thus far......if i was brewing commercial or on a fitty g system maybe ill pull out a micro scope, but basic techniques have worked well for me, Sterility is a key factor in my process,
also cost is a factor,over here a fresh yeast is about $17, abd a 5 gal batch is costion me $7 in grain and hops, Ill rather loose $7 every now and then than fork out $17 per brew, especially when i brew every week, it would become to expensive....
My process to ensure the strain is good at the start is to take the yeast sample, and streak it onto 2-3 differnet plates, once they have grown i look for the nice clean single colonies and take them off the plate and keep them in sterile water, i will then make a starter from the new yeast and make a 1ltr starter, let it ferment out, and then leave it in a bottle , on the bench for a week to allow any bad stuff to keep growing away, on tasteing if it is good, i will make up the slants and store them in the fridge untill i need them, it it tastes off, or not the same as the origonal profile i toss it out... I have used slants that were over 18months old, and they were still good.....i tend to look at the color of the yeast asweel, if its nice creamy white im happy, if its starting to brown or show signs of spots i toss it out
