US -O5 at high temperature in primary?

[RainyLion]

Hey guys,

I've got a pale ale that was about 17C in lag. The next morning I got a brew belt delivered.
I quickly put it on (in the middle of the FV) and rushed to work!
When I got back the temp was 23.5 . . . Eeek! So I read that moving the belt up a bit would make it cooler.

I will let you know If it does.

Has any one got experience on US 05at high temps and how did it turn out?
Plus any brew belt tips or general 05 observations?

Thanks

No it won't. It will just not apply as much heat.

US-05 will work fine at 17C.

Throw the belt away. They are too difficult to regulate.

Hi

Don't move the brewbelt up, as you will just heat the top of the FV, and the bottom will remain cooler. You will then be fermenting at two different temps.

If you are going to use a brewbelt, then you need a ATC unit. These can be picked up for few quid on Ebay, but you will have to wire them.

Hi,

Fermentis' data sheet says the temp range for S05 is 12 - 25°C with the ideal being 15 - 22°C

WLP001 which is basically the same thing, has an ideal range of 20 - 23°C.

So you are fine ! even at the top end of the ideal range.
I have fermented S05 at 23°C with no problems at all....

Oh jesus I just checked this afternoon and temp reading was 25C! I turned that stupid belt off!

It smelt like raspberries, strawberries and other lovely fruity esters!
Not what I want From my beer though!

I guess I'm going to have to see it out without shocking the yeast, I've wrapped it in a blanket!

They're absolutely dandy provided you wire them up to a temperature controller. Which you probably need anyway...

Yeah I'm sure that is an amazing set up! but I imagine that would be another £20 for the box and maybe £10 for a probe (which I've then go to try and fit into my FV)

I Got an immersion heater (today) with a variable temp dial, but its very stiff and hard to use I'm calibrating to around 21 as I'm writing this post( very fiddly ).

I don't really want to have to put stuff in the beer, but I suppose its that or a water bath.

And with a water bath would you need something agitating the water to maintain an even temp?

I'm almost considering this brew a 'write-off' I had one or two problems on brew day. Oh well live and learn Im just going to brew it again next week, and correct the faults!

No need to agitate the water, it works fine as is

The beer will be OK. S05 is pretty neutral and any potential esters will be subtle. Plus, you brewed a very hoppy beer so any esters will be thwarted by the pungency of the hops. In my old flat, I fermented in the back room. I remember an S05 beer that fermented at 23c/24c because of the weather. Turned out delicious.

In case it's of interest, when I dry hop these days, I shoot for around 20c-23c as it brings out the flavours and aromas much more effectively. Dry hopping a beer next to the radiator at the min!

i use a brew belt, but i have it hooked up to a timer, only on for a few hours a day.

my cycles are when the house is its coolest or cyclical so that there is no chance of the brew getting "cold"

You might be surprised.

I think any yeast at 25 degrees will produce lots of fruity esters and spicy phenols, but as floyd pointed out, that can be delicious. Just pretend you were intentionally crafting a saison.

I've found the opposite of this to be true. I know US05 is often thought of as being a low ester producer, but when I've stressed US05 out the result has been some strawberry, peach, apricot and ripe fruit aroma and flavour in my beer. Whilst that can sit alongside hops, to me it muddles the hop aroma and flavour and prevents it coming through clearly. I guess it depends how much of a 'clean' hop aroma and flavour you're looking for.

The reason I always recommend US05 to homebrewers is that it ferments well under a wide range of temperatures. After all most homebrewers do not have temperature control.

23.5 is on the highside but it shouldnt be too much of a problem imo.
