So I went to bottle a pale ale after 3 weeks fermentation (total) and 2 weeks dry hopping. The fermentation looked as normal as any other brew, but the final gravity reading I got from my refractometer read about 1.028 (OG: 1.054). The weird thing, though, is that the beer tastes as good as I could expect it to, not overly sweet or anything. I no longer own a hydrometer to check the gravity that way (it broke a while back), so I'm wondering if the oils from the dry hopping (1 oz Citra in a 5 gal batch) might be affecting the reading. I know I should have checked before dry hopping, but there hadn't been any visible signs of fermentation for a few days so I figured what the hell. Any thoughts?
