No, because you added priming sugar to the final fermented beer to carbonate, the FG will look increased. Always take a reading prior to adding any additional fermentables....

Sure you can, why not? You know how much sugar you added, the math is straightforward.

A pound of sugar adds 44 gravity points to 1 gallon. Divided by 5 gallons equals 8.8 points; times 5/16 if you added 5 ounces instead of one pound, = 2.76 or ~~ 3 points or .003 added to the gravity. So subtract .003 from the reading, you got your FG.

That's what I added, 5oz. To a five gallon batch.

Math + beer = why I left college (the first time)
