What can I do with this yeast cake?

[basszombie666]

So I have a yeast cake sitting in my garage from a Brandon o graff recipe I made since nov. I did cover it with a piece on foil and sanitized it. My garage has been between 40• to as high as 70• My question is, is there anything interesting I can do with this? I remember watching a video of chop and brew where one of the guys left a yeast cake in his office and used it to make a sour. Does that seem right to any one? Just asking overall thoughts thanks.

There is probably some viable yeast. you could take a sample and make a starter from it. I wouldnt pitch it directly, as theres likely a ton of dead yeast.

Well I already washed the primary fermentation. was just wondering if there was anything cool I can do with secondary before I was it out.

Harvesting from secondary is not the best choice. Yes, the yeast is cleaner, but it is also the least flocculent population you're selecting and propagating. Now a cold crash will drop em out, but it may take longer, and you may need to use finings, like gelatin.
