Alright. So after pumping from boil kettle through chiller and into fermenter, I always take an accurate hydrometer reading. However, as fermentation occurs, I sample with a 5ml glass pipette and test the gravity with a VeeGee refractometer. Correct me, if I'm wrong, but I should be using my initial reading against the refractometer reading adjusted for the factor given on sean terrill's site? Sorry for probably not going through the fine print, but it is Friday and I have been drinking beer which may in fact be higher in ABV than I thought. Ha!
