Stir plate heat switch accidentally left on

Long day at work, came home to make a starter for the weekend... after my starter has been on the stir plate for an hour I detect a burning smell. Turns out the heat switch on my stir plate was somehow switched on.

My flask is heaps warm to the touch. Is it fair to say my yeast is nuked??? Nervous to even continue spinning it. I’m spewing as it was my last sachet of WY1217-PC

Would you turf it out and buy some 05 to get by or have a go with it?

Dang that sucks. I wonder how hot it got. You’ve made starters before so you have an idea what to expect. Ride it out and see what it looks like, maybe have some dry on hand just in case. I like to keep a few packs of dry in the fridge as backup, or for spontaneous brew days. Good luck, let us know how it goes.

I ended up not risking it. [emoji30] the flask was way too hot. Sacrificed a $13.50 AUD sachet and will just use 05 tomorrow. Wish wyeast would make 1217 year round. I love it

Dang, so sorry to hear that!
Any clue how hot it became?

Yeast is usually fine up to about 100F/38C. Possibly quite a bit higher than that. You would decant the nasty starter beer anyway after cold crashing.
It also grows much faster at higher temps, until it gets too hot.

I would have kept it, make a new starter and see, or perhaps in a small test batch.

So sorry for your troubles - i did the exact same thing last week and it was the new Bells yeast that Imperial make... so frustrating. I called Imperial and their suggestion was to decant and then propagate a fresh batch of yeast by making a new starter from the cake.

I’m tipping it’d have been above 38c had to throw on the brewing gloves and use a tea towel to transport the flask.

Oh well... at least I’ll know for next time to have a go with it (this is of course hoping there isn’t a next time)
