Hi brewers, I have just recently brewed my 3rd AG lager. My first (Bohemian Pils) and My second (Euro lager) both develpoed this flavour. Im not sure that it is a buttery flavour but more of a light honey/ sweet flavour and aroma. The flavour appeared after about a week in the keg. My last effort was a vienna. Pitched at 10 deg and brought it up to 12 deg over 2 days and left it for 2 weeks. I then upped the temp to 18 deg for 2 days, then filtered, kegged and carbed. One day after kegging I was so proud to smell the clean crisp aroma and taste the awesome flvour of my best lager ever. 4 days later GONE, the wonderful malt aromas and clean lager taste was replaced with the same flavour and aroma as the last 2 lagers.
I know 2,3 pentanedione has a honey like aroma and flavour but the taste threshhold is 10 times higher than diacetyl, so it couldn't be could it? And as I mentioned I dont really think it has a buttery flavour or aroma. I have perfomed a diacetyl rest, then chilled for 2 days, filtered and kegged.
What could this possibly be? Does diacetyl or 2,3 pentanedione take a few days to develop or is there from the start if its there at all?
