w34/70 at 43 degrees?

I'm planning a Vienna lager and wondering if 43 deg is too cool for this yeast. Anyone have experience?

I have some washed 34/70 that I'd like to use, and that's the warmest ambient temp I can get in my fridge. Temp controller build still sitting on the shelf

Any insight would be greatly appreciated!

If you pitch enough it will work at that temp. I've gone close to that, and a brewing buddy of mine has used it at 43. If you can get it going the ferm temp will be higher than ambient anyway. I think you'll be okay but make sure you pitch enough. And if your slurry has been sitting around in the fridge or whatever, consider dumping it and using fresh yeast instead. If you are racking and repitching you should be okay.

Good luck!

Thanks!
