misusing yeasts in storage

Postby walders123 » Sun Oct 15, 2017 11:11

A couple of days ago I had a brewday with approx 40% pilsner and rest wheat grain. I was unsure about my yeast (WLP351 Bavarian Weizen Yeast) which I had sitting in my brew fridge for well over a year. Now, the temperature in there varies from lagering at 0 deg c to fermentation at 22 deg plus.

For my usual yeast schedule, I added yeast to 1 litre dme solution and hoped for the best. it had a quiet start but after 3 days a light krausen appeared. I then added to top up to 2 litre. Another day and it was good to go.

Question, have you had yeast that you didn't expect much from? or any fails

Pitched a packet of Notty a couple of years out of date, took 3 days to take off but it still worked.

Yeah, some crappy s-33 that died at 50% attenuation and kicked out tonnes of sulfur, badly stored. I think you'll be fine as you've grown some new yeast up though

Just kegged the brew I was referring to and it took it down to 1.008 in the end. It tastes great, I must remember to use Notty more often.
