@brulosopher - how do you like the beerbug? I'm thinking of buying one as a gift to myself for Christmas to monitor my speed lager fermentations so I don't have to worry about taking hydrometer readings and risking oxidation.
With all due respect, there is no need to worry about oxidation from taking a gravity sample. The Beerbgug is a neat toy, but it is in no way necessary to prevent oxidation. I will reference my old standby line...."If you can't take a gravity sample without compromising your beer, perhaps you should consider taking up knitting instead." It's a JOKE, OK?
