Bad Nottingham Experiment with Pics
 
I started this today, with the bad lot number etc.

Ignore the "122" on the thermometer, that's a default alarm setting that can't be turned off, it is not the temp of the probe. The temp is on the left side of the display.

91 degrees, packet says 92 is the upper limit for proofing.

I put 1/8 teaspoon of the yeast in, set the timer for 15 minutes, according to package instructions.

I noticed this in the packet, yeast sticking to the sides. I'm no expert, but I think that's a no-no. Can anyone shed light on this?

I never noticed any visible activity, the only thing I noticed is that some of the floating pieces began to sink around 12 minutes. Nothing remarkable or noteworthy.


According to packet instructions, I stirred all the yeast into suspension after the 15 minute mark.

I made some 'wort' with table sugar and water. I got it to within 5 degrees of the yeast solution temperature.

Side by side.

Combined Wort and yeast.

I poured off a tube of the solution. Starting gravity is ~1.027

I'll update whenever I see a change in the hydrometer, or obvious lack of change. I followed the directions to the T. Now we'll wait and see.

I thought the yeast sticking to the side was a problem with their packaging that they were working on.

I only used Nottingham a few times. I remember some of the yeast sticking to the inside of the packet. My beers took off and tasted okay so I'm assuming the yeast I had was good.

It is most likely static electricity on the plastic baggie and of no concern whatsoever to the yeast.

I've never not seen dry yeast cling to the packet.

I used Notty the other day and it definitely stuck to the sides of the package. I didn't have any problems with it and it is fermenting fine.

Is that normal for the yeast to sink straight to the bottom, with no action?

i wouldn't count this dead until you try it in actual beer wort. i don't know that you're 'supposed' to see activity when you rehydrate the yeast.
