Depends on the beer, but in most cases, it will be pretty nasty!

If you’re making a Belgian style, you might get away with it, otherwise I think most likely this is drain fodder.

It's a pale ale from the brew dog diy list,
I'm going to have to see it through but I don't have high hopes.

Might be time to get myself a brew fridge

I used to ramp up my brewing in the spring so that I could give summer a miss. I got a freebie fridge probably five years ago. When not fermenting at 18C or crashing at 3C it spends most of its time storing bottles at 12C which is quite a nice temperature to store our stash of chocolate during the heatwave.

Yeah, I brew in stock up in spring to skip July and August.

Perhaps ough to scrounge a fridge, but just started "ferment in kettle" and that is just sooo nice.

Could do with getting a brew on myself.

Ale yeast can die at those temperatures, leaving an umami or marmite taste. I doubt you will have something that anyone can enjoy. You may be able to persuade yourself it's alright. You would definitely send it back in a Pub. [-X :D

I thought it was only the Belgian yeasts that could handle anything over 25c ish without stressing and creating off flavours?

Not wanting to start another conversation about the pro's / con's of kveik yeast but recently had good experince using it but I think you have to choose your type of beer carefully.

I used 1 year old slurry of VOSS KVEIK in a hoppy pale are.

I fermented a couple of weeks ago and could only get it up to 29°C it's operating temp is between 33-40°C.

Good orange peel flavour against a double dry hop drop of Mosaic. A really nice beer.

If the slurry can last another year I'll be doing the same next year.

Cheers

Kveik eh?

Could be the answer but if it's temperature range is upwards of 30c, how would it perform at around 25c ambient?
Any special treatment required?

Special treatment: sounds like turning the heater up. 😁

I wonder how crafty Norwegians managed to maintain fermentations at 40*C, historically. No doubt there’s a very colourful explanation or two.

I've often wondered about that. Perhaps saunas were invented to ferment beer :D :D
