Yep that's about it, remove airlock, take sample, test sample, return sample to carboy OR sample is consumed for "testing" purposes.

I NEVER return a sample to the carbouy. While the risk of introducing some unwanted organism is small, it IS a possibility; besides, why wouldn't you want to drink that hydro sample?

Normally, you'd drink the sample because you need to know what the wine tastes like at every point of the process.

I also do batches of that size, I now have a refractometer which refractometer which removes the problem, but when taking hydro readings I've taken to pouring a tiny amount of it into a glass as a taste test and the rest goes back in.
