I've noticed the same thing, as have a couple friends. I've assumed it's a combo of a bit of extra alcohol from bottle conditioning, fresher beer, yeast and inaccurate calculation. I use the equation: OG-FG*131.25=abv. That's per my brewing software. I'm sure that temp fluctuations and the presence of alcohol effect readings a bit and this is probably the main reason some of our brews seem stronger. That or we're buzzed when we do the math and drink a batch of '5.8%' beer that's really 6.8% thinking the whole time, 'man, this is one punchy 5.8. Redhook esb's 5.8 and it doesn't get me this wasted. I love homebrew!!!'
