Brewing 10 gals of a dunkel weizen with a new brew buddy.
I bet it’ll be fine. I have some year old Kveik Voss leftover from an overbuild. Later this summer I plan on putting back on a stir plate and seeing if it’s alive. If so, and I think it will be, I’ll brew a grapefruit pale ale with it.I will brew *something* because Wife will be out of town and I haven't brewed for a while. I have not figured out what exactly yet. My kveik yeast sludge in the fridge is over a year old, so I should probably try to wake it up today or tomorrow. (I have other yeast I can use if it's too far gone, but it will make me sad)
Last year I just used Voss Kveik @ 72 ... came out fantastic after 4 weeks cold lageringPlan is to brew a Octoberfest fest this Saturday. Hopefully this year it turns out better than the last few years. I seem to have trouble with Octoberfest.
I have a big jar of 1 year old yeast slurry that is still nice and creamy off-white and smells good. I made some starter wort today and added a big spoonful of it. I also found two small jars of washed yeast that's 18 months old. (also Voss kveik) If I had more time (in case of a failure) I would have used one of them. I suspect they are still good too but might be slow to wake up.I bet it’ll be fine. I have some year old Kveik Voss leftover from an overbuild.

8 hours later I have bubbles. The year-old stuff is not just alive, it's still healthy.I have a big jar of 1 year old yeast slurry that is still nice and creamy off-white and smells good.

I find reports of yeast viability to be way more vibrant than common knowledge. I had a pack of Imperial that I was given for free by my LHBS that was almost 8 months old actually spill out of my 5l flask on a stir plate.8 hours later I have bubbles.
