Oddly enough, I own one of these but almost never use it. I find it annoying to convert brix to gravity. So I wash my hydrometer and drop it directly into the fermentor. I take later gravity readings the same way, unless I'm doing something with a lot of fruit pulp in it.hey divr
i think the real answer is to invest in a refractometer

I've never had a problem doing the readings this way, no infections etc. The hydrometer is rinsed in extremely hot water just before it goes in the fermentor though. My fermentor is an old 1 gallon plastic juice jug.
