| Since you used such a huge amount of malt you're bound to be left with a
fairly high final gravity. However if you are worried that your beer hasn't
fermented completely, leave it for another week and check the final gravity
again. Also there's no need to worry that your beer would spoil during this
time, unless you sanitized your equipment really badly during racking.
In fact you can leave your beer in the secondary fermenter for even a longer
time if you want. If you sanitized well then there's nothing you'd need to
worry about, you'll only end up with a beer with less sediment in the bottles
and probably a better taste.
In my opinion there's no need to add more yeast. Since you kept the beer in
primary for only six days there's still lots of yeast floating around, it will get
the job done if there's anything let to ferment. |
