Found out active dry yeast loses half its punch after just 6 months on the shelf

I was digging through my pantry last night and spotted a jar of yeast I bought back in March. Checked the date, popped some in warm water with sugar, and barely any bubbles. That stuff is basically dead after half a year even sealed. Has anyone else tested old yeast against fresh and noticed a huge difference?

Doesn't surprise me, my own energy fizzles out after six months too.

Maybe we just finish things faster when we're actually onto something real?

and this is why i keep 3 side projects going at once. soon as one loses its spark, i switch to the next. keeps the momentum alive.
