Jamils new pitching calculator kicks ass

Uh... that too...

Sorry to disagree (sort of) with the Pope, but...

A single negative does disprove a theorum. If Bryan is making good beer with 2 year old yeast slurry, then 2 year old yeast slurry can't be intrinsically bad for making beer.

Doesn't matter how much he theoretically shouldn't be able to do it, if he does, the theory is wrong.

That in no way means Bryan's way is the best, it just means that it is at the very least; viable.

Question. If you can grow up a good quality starter from a few live cells on a slant, why would the few live cells in an "old" slurry yeild inferior results? Presuming of course that you take care to decant autolysed/dead cells etc

How would you know which are dead? You'd need a microscope and staining and you'd have to hand pick the cells. Also, as Jamil pointed out, the main problem is bacteria feeding on the nutrients expelled by the dying yeast, i.e. infection.
So I guess if you could select a few live cells from the slurry then you could grow a starter just as you would off of a slant, but why risk it? It may be fun to test out the theory, and it may be interesting to rach yeast (I did it for six months or so), but in the end if you have access to fresh yeast why risk it? Unless of course the Oil is running out!

I'm actually more interested in Bryan's storage method. How do you prep the slurry for this long term storage? What temps do you store at and in what type of container?

Ahh see, thats where my complete lack of experience comes to the fore. I have no damn Idea! I was just asking.

I kind of thought the whole "starter" process would take care of that for you.
Give it a bit of fresh wort and a bit of time. take a bit of the stuff thats in suspension and it will have the live cells. Grow from there. But I'm only guessing. None of that takes into account the infection thing though.

That's the truth, but you need to extract it, transport it and process it. All of these steps require petroleum products of some kind. You need fuel for the extraction equipment and trucks for transportation, plastics for saftey gear, processing equipment, etc.

Think about it. Oil is EVERYTHING. We get almost all of our products from it one way or another.

We are so screwed.

Thank god for beer.

amen to that

Nah, oil is the least of our worries...we also have a large supply of the other combustible fossil fuel - Coal. If you can gererate electricity, you can produce Hydrogen, which takes care of transport.

Our biggest problem would be the technology required for the pointy end (process/react). Be plenty of time to work that out before the coal runs out.

You're still screwed, though (unless you invade). Thank god for beer.
