I drink all of mine in the name of science. I think it's important to keep track of the taste as it ferments. For example if I'm getting some off flavors it's usually due to too warm of fermentation So I start up the old swamp cooler
For an OG: I don't take one too often, I measure my mash efficiency pre-boil and can calculate my OG. When I do take one, I use a sanitized hydrometer and jar and return the sample to the fermenter. I've tasted them before and don't like them.
For an FG (or intermediate reading): I drink the sample. I think it tells you a lot more about how the beer is doing than just the gravity measurement.
I use a refractometer for the OG, so it's a tiny sample. I actually collect the sample in a sanitized dram vial and test it the next day (or sometime later since I put it into the fridge) for the OG [most of the time]. For the FG (I usually don't take readings until the batch has finished), I drink it. I've been using the hydrometer (my original one) for the FG, but am considering using the refractometer for the next batch for both readings.
