I made a bitter in December. I used jamil's recipe which included WLP002. It had diacetyl, the most I have ever had in a beer which includes lagers. I made the exact recipe after the New Year and switched to S-04. No diacetyl. My fermentation for WLP002 was two weeks @ 68f. It tasted great right up until day 10. For some reason, that was when diacetyl reared its ugly head. I am a big fan of White Labs yeast, but not this one.
