Beer fermentations hit 30c ?

[Berry454]

Hi guys

Started two new brews, a IPA kit with added dark grains to create an Amber IPA and a 5 gallon batch of an all grain hazy IPA.

Due to fermenting in my garage temperature was very low.. 14 Celsius and fermentation seemed to stall.

I added a 500w oil filled radiator to the garage but it made absolutely no difference.

As a last resort I put the oil filled radiator between both fermentation buckets and covered the entire lot with a blanket.

Woke up today and both fermentations are bubbling away at 30 degrees Celsius!

Will this harm my beer in the long run?

Turned the heat wayyy down on the radiator so hopefully the temperature drops to a healthy 20 ish degrees.

I did think how is this any different to fermenting in summer when my beer ferments regularly hit 28-29 degrees Celsius and never noticed any issues with them.. but it has got me a little worried!

What yeast are you using?

This is just likely the best answer to your question you'll get. The yeast won't know the difference between heat from your radiator and heat from summer.

But you may find that now you've removed the heat source, the temperature will crash and the yeast might go into their dormant phase and your fermentation may stall.
