Took a hydrometer sample today, and sampled it as well. It sat for about 3 months in the primary (take that, naysayers).
FG came in at 1.024, down from it's initial 1.108 - 76% apparent attenuation, 62% real. Wyeast says 69-73% for 1728, so I think it's pretty good. Oh yeah, ABV is at 11.2%.
The flavor profile is giant malt flavor, smoky overtones, with a massive alcohol burn. Delicious stuff, although I think even 12 oz. might be a bit much, it's so rich. This beer definitely needs to sit for a long time. I'm going to rack it into a smaller secondary to minimize O2, and to avoid tempting the autolyzing gods any further.
Also of note, BeerSmith put the estimated FG at 1.023, so it did just fine.
