Peach taste?

[qvantamon]

So, I just secondaried a batch. I pitched Coopers at around 80F (I know, I know), and cracked a window hoping it would cool down before the Coopers woke up.
Long story short, I woke up to 2 inches of krausen and still above 78 (even though ambient temp was at 65). It only dropped below 75 after airlock activity stopped, so it's safe to say it fermented hot all the way.

Anyway, I tasted my hydro sample, it's a bit "hot", as expected, and it smells and tastes strongly of peach. I've had banana, cider, green apple, butterscotch, but this is the first time my green beer tastes like peach. I KNOW it's still green as hell, but it's just that this is news to me, and I haven't seen "peach" mentioned as an off-flavor yet. Is this a Cooper's thing, a warm fermentation thing, or a green beer thing?

Sometimes yeast can give off a peachy flavor. I believe it's documented in US-05. I've got an IPA, fermented with US-05 around 67 degrees, that's almost ready for drinking and the hydro sample had a mild peach flavor that worked quite well with the hops. I've never had it show up with Coopers yeast, but that is a pretty warm ferment temp.

All kinds of fruity flavors are possible with a high temperature fermentation- I've heard of peach with S04. Sometimes there is a bubblegum fruitiness, or banana flavor. Peach isn't uncommon.

I just had it in a batch of Haus Pale Ale using -05. It was a welcome addition, but has actually faded in a short amount of time.

(Ferment temps were 60 degrees.)

I recently tried a beer brewed by a couple of friends of mine that had a noticeable peach flavour, which really worked well in the American style wheat beer. I believe it's something that is desirable!

IMHO, if that was the primary issue you had with Cooper's, and the beer is still green, you kinda came out lucky. I've had vile results with Cooper's and don't touch the stuff...

Coopers Brewery has been making beer since 1862. The Coopers brewing yeast consistently makes a clean beer.

Peachyness can be awesome! Next time that you have a Arrogant Bastard look for a peachy ester. It totally is one of the things that makes AB in my book. If you don't like it ferment at a lower temp and it should dissappear..
