So now, I've taken the FG and I can see that the yeast has stopped. So do I now leave the beer in the primary for another couple of weeks? It's only been in there one week thus far...thanks.
Yes. Leave it alone for another couple weeks. It will help give you the best results.
Personally, I would leave it in the fermenter 4 weeks total.
3-4 weeks is fine unless you are going to secondary the beer. what kind of beer are you making? can you post he recipe?
I made an American Pale Ale I will try to get the recipe on here
I am assuming I should leave the air lock correct?
yes, leave the air lock on
