I brewed this stout back in October and have had it kegged ever since. Just lately Ive noticed a sort of grain type taste to it and it has a smell that I recognise but not sure what it is.
I'm sure the smell is something I usually smell on brew day (if that makes sense) perhaps the smell of wort at the end of boil, Im not really sure I just know it smells familiar. It didnt have this grain taste or the smell when I fist started drinking it.
Any ideas or suggestions as to what it might be? Has anyone had this before? Ive brewed a few stouts and never noticed this before in any of them.
