For some reason, I feel like I am not getting an accurate Hydrometer/Refractor reading at the end of my boil. When I take a sample from the Boil Kettle, my Hydrometer Flask is filled with Floaties. I feel that this is affecting my readings. The reason I say this is that this weekends brew, I wound up with an afficiency of 64%. I normally average between 75-80%. And the wierd thing is, is that it is just this Brew. Last weekend I brewed a Russian Imperial Stout and I got lower efficiancy. That is to be expected with such a Big Beer. But this past weekend's brew was a dead Guy Ale Clone, so my Efficiency should have been right around 75%. My Pre Boil Efficiency was 74.8%. What is your method for a clear Hydrometer Sample from the Boil Kettle when you All Grain?
