Going from 1.075 to 1.012 puts it at 8.4% ABV...
What is the brew?
I would have left it on the yeast (since it's using ale yeast) for the duration. Especially since it had a high OG... Since you've already racked it off the yeast, you might as well leave it in the bright tank for at least a few weeks, or longer. IF it doesn't taste hot, then just give it time to finish up... Take a SG reading (a single low SG reading isn't a FG) in a few weeks, then another a few days later and compare. TASTE the sample after you've taken to reading. IF it tastes ready, bottle/keg it... If not, give it more time...
I hate how so many instructions tell people to rack off of the yeast after X days, or when fermentation slows... Doesn't mean it's actually ready to be moved, or that it's even a good idea to rack it. I'm not the only person that's tossed racking to a bright tank out the window (as a process)... There are a few cases where it makes sense, such as racking OFF of a flavor element and onto another. Or after several weeks on the cake, and you're planning to age it on another element for weeks more. Otherwise, chances are you'll get a great brew by leaving it on the yeast... There are people that have left their brew in primary for MONTHS with zero ill effect (Revvy has mentioned going 6 months with one brew)... Personally, I've gone 6 weeks so far and had a great brew because of it. I'm not even thinking about taking a brew off of the yeast cake until it's been there for 3-4 weeks... Every time I do this, I get really, really clear brews, that taste great. I just wish I had known to do this for my first two batches...
