Yeast Dating and Defining Old & Useless Yeast

14 posts in this topic

I read on the DIY Coopers site that the yeast packing is Julian dated.

 

My 1st package says "09016 B"

My 2nd package says "Mr Beer 16816 5g Brewers Yeast"

My 3rd package says "Mr. Beer 18015 IM 5g Brewers Yeast".  

 

Were these yeast packages made on Day 90 2016, Day 168 2016 and Day 180 2015 respectively?

 

Does the "B" mean Brewers Yeast? 

 

What does the "IM" mean?

 

How old of a yeast is too old? Do you think 18+ month old Mr. Beer 18015 IM 5g Brewers Yeast will still work?

 

B.

You have the dates correct.  They are Julian dated.

 

Josh would have to explain what the letters mean.

 

The oldest yeast may be good and it may not.  It really depends on how it was stored.  If it sat on a store shelf for 18 months, I wouldn't guarantee it will work.  But if it was purchased a year ago and stored under refrigeration since that time, there is a very good chance it will still be good.  You can always proof it by rehydrating it.  Boil about 4oz of water for a minute and then cool it to 85 degrees, keeping it covered.  Sprinkle the yeast over the top of the water and wait 10 minutes for it to rehydrate.  If the result is a creamy liquid with some bubbles on top then go ahead and pitch it in your wort.

Hey, Hoppy.....have you ever dated yeast?  I tried to go out with a pack once.  We were going to meet at a bakery.  I got stood up, and the rest of the night went flat.

Okay, so I'm confused.  Are you now officially "back?"  🤔

Still on a quazi break.  Still have some personal issues to take care of, but it's just so hard to stay away
