I've got two beers in fermenters right now:
The first is an IPA (which I still need to dry hop!) which was intended to have an SG of 1.078 but is between 1.075 (if you trust my refractometer) and 1.093 (if you trust my digital hydrometer). It also happened to end up with 50% on my floor during the boil -- but I promise, that bit didn't end up back in the fermenter.
The second is a porter that was intended to have an SG of 1.051 but is between 1.069 (if you trust my digital hydrometer) and 1.082 (if you trust my refractometer) and happened to, uh, have some of the hops included as part of the mash. Yeah, I had some issues that brew day.
