Hey all, it's my first time brewing and I am brewing all grain. After I batch sparged (following beersmith) I realized I didn't have the test tube for my hydrometer and had nothing long enough to put it in so it kept sinking to the bottom and I couldn't figure out the OG. I did an iodine test and saw that I had conversion, just don't know my efficiency. Am I totally screwed as to finding out what my abv will be?
