Do you normally put the (sanitized) hydrometer directly into the fermenter, or do you pull a sample from the fermenter, then put it in the hydrometer test jars to test? I've been thinking of putting the hydrometer into the fermenter once the krausen has completely subsided, then taking a look at the reading and leaving the hydrometer in there so I can take another reading in a couple of days to ensure proper attenuation. I guess this saves having to sanitize the hydrometer twice and it saves having to sanitize the cup twice (I sometimes put a sanitized cup into the fermenter to draw a sample).
