Hi!
I'm currently doing a series of beer-archaeological experiments trying to recreate an ancient Armenian beer mentioned by the Greek author Xenophon. One of the things I'm is trying to figure out is why this beer is described as having bits of grain floating in it; an idea I'm testing is whether the spent grain was left in so it could be used as a yeast starter for the next batch (I recently posted in a different thread on this).
Anyways, I started with pre-packaged yeast but have now switched to wild yeast. I brewed a batch, left it out on a sun porch in Illinois for 12 hrs in approx. 45 degrees F. The first weeks, the brew would get some fuzzy mold that I would scoop out. But now, three weeks into fermentation, the brew has these strange white geometric objects floating at the top that no longer looks like fuzzy mold. Does anyone know what this is?
Thanks!
Kyle
