The German Blonde is described as being crisp. I would expect (or guess) the FG may be in the range of 1.006 to 1.008. Give it time though. Take a SG reading about day 14. By this time CO2 produced by a fermentation that is finishing should be nil if the fermentation temperature was in the mid to upper 60°F range. May be able to do just one SG reading since this is a one gallon brew. If the SG sample doesn't have too much CO2 in it and looks clear you may be ready to bottle. Extra time in the primary will not degrade the quality of the beer and will be much safer if only one SG reading is taken.
