Spreading the Joys of Home Brewing Throughout Philadelphia and the Universe!

Anyone feel that their hydrometers aren't giving them accurate readings? It seems like my past 2 brew days my efficiency has gone from 71-72% to 45% last week and 55% this week. At first I thought maybe the homebrew shop messed up my grain bill, but then i was thinking that maybe my hydrometer for some reason all of a sudden started giving me false readings, resulting in my apparent low efficiency numbers. I placed it in my tap water and it was reading close to .990, which i thought it would be closer to 1.000 . Comments/suggestions from anyone?

I believe in distilled water it should read 1.000. It could be off. I think sometimes the little paper inside sometimes can move. I would go buy a new one. You can also take .1 off of all your measurements, but I am not 100% sure how accurate that would be.

I switched to a refractometer. My brew day got so much easier. I can test the wort at any time during the boil by taking a couple same drops and see where I am at. The readings are in Brix, which you can convert to Specific Gravity. Using MoreBeer.com's Refractometer Spreadsheet, I can even use it during fermentation.
