That is so cool!
Cheers! (Poor li'l yeast...never had a chance to bud... )
Try a batch of your tap water treated with campden. You most likely won't regret it, and save $$ per batch along the way.
That's really cool.
Is this what we are seeing?
- Single yeast cell
- Exposed to distlled water
- Cell lysis and the cytoplasm being extruded ito the media.
I remember how my mother when baking fresh bread would take the dry yeast add it to warm water with a teaspoon of sugar just to see if the yeast was good, I'm pretty sure this is how re-hydration got started, as I remember it was just tap water or even well water and in all cases it worked, you just let it set until you see a small layer of foam on top....I think people are getting carried away with the details too much...as Mike said years ago which i just love this saying ...."just do it"
2) boiling doesn't remove chloramines and other amines compounds, are they affecting yeast
Yes this is a single yeast cell. This was after 10 minutes in distilled water. It is labeled with a fluorescent membrane marker that should normally just be visualised as a nice ring around the outside of the cell, the pressure had already damaged it giving the 'patchy' appearance. In longer videos the cytoplasm and cell contents keep being extruded for another couple of minutes before the whole cell breaks apart.
Sean Terrill found that rehydrating dry yeast in water (with some mineral content, not distilled) was better for yeast viability than wort...

Honestly, if it's one of the big name dried yeast of today the rehydration comes from the water in the wort. Same reason the big guys purposely make dry yeast that needs no starter or wort o2 boost to get them going
Just saying. (Does anybody still use that phrase[emoji3])
