I went to pitch a real wort starter for a Golden Strong last night, and had planned on using some 1214 I'd washed. I hadn't realized I'd washed it 7 months ago, and when I opened up the mason jar, it smelled kinda rotty. I opened up the other jar I had, and it had a small floater that looked like mold.
In a pinch, I opened up the only other belgian yeast I have, an 8 month old jar of 3787 that smelled clean and good, so I used that instead.
I followed the same procedure for washing both, boiling the washing water and the jars, and were stored in the fridge. The 1214 did have a noticeable amount of trub, while the 3787 was all clean white yeast. I'm wondering if I was smelling autolysis from the yeast sitting on the trub?
