Is dry yeast bad for health?
A little yeast in your body is good for you. Too much can cause infections and other health problems.

If your yeast is “dead” or “inactive” then you will need to get new yeast—there is no way to revive it or liven it up again once it goes bad. Dry yeast can last up to 12 months, but there is no guarantee. We recommend storing it in the refrigerator, especially after it is opened.

What did they use for yeast in the old days?
Besides brewer`s yeast, homemakers in the 19th Century used specially brewed ferments to make yeast. The basis for most of these ferments was a mash of grain, flour or boiled potatoes.
