I didn't measure the OG because I forgot but I am encouraged that it should be close to 1. My beer is NOT dark so question is how does that statement realte to me. Could you expand on what you mean. I could make many wrong conclusions from what you say 'depending on how "dark" the FG close to 1'?????

Darker beers tend to have a lot more nonfermentables that contribute to the gravity of the beer. It's not uncommon to have a stout with a FG of 1.020. But with a lighter beer like yours a SG of 1.000 or very close to that usually means your fermentation is complete.

However, it's a good idea to let it age in the fermenter for a while before bottling (up to a month is fine) because that will give the yeast time to clean your beer up and make it more palatable.
