What’s the best way to take an accurate original specific gravity reading? I use a sampling thief to collect a wort sample from my carboy before pitching. The readings are different depending on how long the wort settles before measuring and how deep into the carboy I dip to collect the sample. Is this caused by picking up different amounts of sediment in the samples? Should the sample come from wort that is relatively free of sediment? Should specific gravity be measured before pitching?
This question brings up some issues that I have experienced over the years and I have been somewhat surprised by my observations. I usually collect a wort sample from a sample valve
