Completely random question, but could this be done with flavorless gelatin? Additionally, wouldn't this be good for those of us who don't have the space/funds for ferm temp control? If the yeast can only ferment at the pace the solution passes through the membrane, temp shouldn't get out of control, right?

I don't have much experience with gelatin, but I've never seen it get as firm as these beads are. They really feel like a plastic polymer of some sort. I have to imagine that gelatin would become a soupy mess.

Your speculation on temperatures sounds plausible, but really I have no idea. Based on my experiences, I'm confident that these beads will ferment beer, but everything beyond that is just a guess.

I will do more experimenting at some point, but it might be a while! Right now, my nearest homebrew show is thousands of miles away, so I'm not able to do much until I get around to figuring out how to malt my own barley.

Did anyone out there ever finish their own experiments with the technique Malfet outlined in the OP? I know someone was going to try this with some Brett strains, I'd be very interested in those results.

Yes. From what I recall they posted on here originally asking for some members of HBT to volunteer to try a new fermentation technology. They weren't very forthcoming about details when asked. Then it turned into a kickstarter campaign and they were asking people for money here out of the blue.

Or something like that. The OP (if you read this thread) insisted that as he never had any info on what the Mupor technology was and therefore wasn't able to speculate on whether or not the experiments detailed in this thread were at all related.

Starsan absolutely destroys yeast. The detergent opens up the cell to allow the acid in.That is how starsan kills, it's not just acid.

I remember someone posting they thought StarSan was a fraud because it didn't kill his yeast.
