Safale S-04 Cal-Commen

So I made a Cal -commen type beer with pale malt and 25% corn adjuct, and used S-04. SG was 1.045 finnished @ 1.012, Used A Hallertau hybrid (called US- 4/78 )1oz @ 60
I recon the fermentation temp was stable @ 19 C
Bottle conditioned with sugar 2,5 weeks @ 15C

The thing is it has a distincte citrus flavour?
what can it be?
Dont think its the hops because it did not taste like that in other experimental batches?
IS it still just "green"?

Its probably a combination of still being green and esters from the s-04 yeast. That yeast is not a clean fermenting yeast and is more intended for English style beers where fruity esters are desired.

Good example for a clean fermenting Fermentis yeast........?

I've always used Safale S-04 for my pale ales and never had estery flavors .

19 Degrees C is a good temperature for this yeast strain . It will produce such flavors at around 24C and above .

Never used S-04 before, so cant speak to whether that's a characteristic or not. I would think you are ok with fermentation temp of 19C / 66F. S-05 is clean fermenting though from the one time I used it in a cream ale.

try wyeast 2112. great results.

S-05 is a very clean fermenting yeast. Probably the cleanest dry yeast on the market.

Well this in also interesting, but how would you interpret Fermetation temp, or what do most people refer to: the temp of the beer or the temp in the "closet"?

"Fermentis" recommends fermenting at 15-24C with S-04 .

I always keep my ambient temperature at 19C and I've never had estery flavors .
