RIP BRY-97
« on: January 12, 2023, 12:28:19 pm »
During the early daze of the pandemic I was having trouble getting what I needed to brew so among other things, I bought a brick of BRY-97.   The exp date was Apr ‘21 so before trying it out on a brewday I decided I’d test a little to gauge viability.

To test bread yeast I can add some sugar and yeast to warm liquid and see the foam develop. So, I figured I’d try the same thing with this expired BRY-97.

I have seen bread yeast develop foam within 5-10 minutes. I am going on an hour and a half and see zero action with this BRY-97.  

I know BRY-97 is known as a slow starter so I am going to leave it out and see how long it takes. Of course, wild yeast or other beasties might give me a false positive in a day or so. To try to provide a control I set a sugar water only sample to see which (if either) foam and when.

Place your bets….

It is slow in my experience.

My bet would be it's still good.

Sorry… just my remnant of a brick. Mods feel free to chg the title if warranted.

3+ hrs:  nada.

1+ days: can’t say it’s nothing but I can say it’s weak. I have a bit of foam slightly larger than a half dollar. Nothing to commit to a brew. Most of it was just laying on the bottom. Time for new yeast.
