Yeast recovery experiment question...

[AviatorTroy]

I wanted to try the yeast recovery method so I dumped the yeast from 2 bottles of Hefe (WLP300) into a 1L flask where I had some starter wort made up from extra light DME and 1 hop pellet. I was happy to see it quickly show signs of normal fermentation in that flask.

Then I had to go out of town for three weeks.

I get back tomorrow. What will I find?

A. A perfectly usable sample of yeast that I just need to rinse then dump into another starter for a batch?

B. A moldy disgusting mess?

C. Something that looks and acts fine but ruins the batch of beer I am planning on brewing this weekend.

Anyone use yeast that's been in a flask in the closet for 3 weeks?

(I am very meticulous about sanitizing so it might be OK)

I vote for A.

Put me down for giant mess. Two vial + 1L flash= yeast volcano. Just my 2cents.
Hope it turns how well

Those wheat beer yeasts are fairly prone to losing their propensity for producing 4-vinyl-guaiacol.

I would at least taste the starter wort and make sure it has plenty of clove before you go further.
