Well attenuating, floctuant yeast and proper fermentation conditions or higher than acceptable temps. Basically, you had a very good strong fermentation, possibly a bit too strong which made is throw off esters but anyway, good job on it. If you like the flavor of it, you did very well.

+1 to this.

I do take a FG right before I rack to the keg but only to make sure my fermentation didn't get stuck and so I have a rough estimate on the ABV percentage. I don't do the 2-3 readings over 3 days thing. After 4 weeks in the primary or 2-3 weeks in a secondary it has already done everything it's gonna do.

ya, give it at least another week, and then feel free to bottle it. since it was an extract batch, you can calculate what your OG was supposed to be since its a known amount of sugar. if it was a kit, it'll be within a point or 2 of whatever the target was (given you hit the correct volume).

In my short but illustrious brewing career , I was a madman about checking OG and FG on my first two extract batches, then I read all the stuff abiout how it doesn't matter, so i didn't check on my next 8-9 batches, and, of course, they turned out just fine.

Once I went AG, however, I'm again a madman about OG and FG, because you can't DUPLICATE past recipes without hitting the same OG and FG. I would never tell a newbie that they shouldn't worry about taking gravity readings. I think this is a necessary skill that you need to have. However, once you have the basic skills of gravity reading down, you can certainly take a break from it as long as you are not concerned with trying to replicate batches consistently.

honest question about OG, FG... in a sugar water mixture, your reference is 1 because water is 1. however, when you mix water and ethanol, the density decreases slightly, and thus the reference(if all sugar is gone) would be less than 1. So isn't it possible, if you're getting a 1.005 reading that the actual sugar/water content is closer to 1.008 or more? I mean not that it's a huge difference, and maybe it's all figured in when people do these types of readings. I'm just curious.

Wisski - While that is absolutely true, we don't go to that trouble. When an expected final gravity is supposed to be 1.012, they mean 1.012 in the same way we all see it - (accounting for temperature, of course) - no tricks of .003 for alcohol content, etc.

So, scientifically speaking it is lower than the reading, but for all practical purposes, we use the same scale.

ok that's what i figured, but i see some people saying things like "take your og, and subtract your fg, then do some mathematical magic, and you'll get alcohol content." And that just doesn't seem like sound science to me.

As a noob who is planning on bottling first batch this weekend, I think it's important to check gravity on kits so A) you know how to do so and B) to alleviate concerns you have about your batch. For example on my latter point, I had absolutely zero activity in the airlock so I got overly worried and posted messages here and all the advice was to check the gravity. And lo and behold, everything was fine.
But once you know how to do it the right way and if there are no concerns about your batch, I think your points are right on.
