An FG of 1.000 means the yeast have converted about 82% of the sugars to ethanol. There's still a ton of sugar left in a beer that big.
Alcohol is loaded with calories. Fermenting a beer to 1.000 (or lower) makes very little difference in it's caloric content.
I am amazed that there does seem to be sweetnes still in the brew since the hydrometer indicated 1.000 FG.

There's still a ton of sugar left in a beer that big.Real Attenuation is 81.1% if the OG was 1.071 which will get you 1.000 and 9.7% ABV. The 1.000 reading is skewed by the presence of the alcohol- which skews the hydrometer reading if that makes sense...
This weekend I will take two cups of beer and boil it to remove the ethanol and once it has cooled. I will add enough water to bring back up to two cups and recheck the hydrometer reading. This should give me an accurate reading of the Real Extract value and then be able to calculate what the actual residual sugar is still in the beer. Thanks for your ideas. Will update.

Will update.That will work, but why bother? If you have the OG and FG readings you can calculate the real extract:RE = .1808*OG + .8192*FG
