Sorry if this is a repeat question but I was not able to find it in searching. I am prepping to do my first batch in week or so when my equipment arrives. Since I was short sighted and did not add a test jar to my order, is there any reason not to take OG and FG directly from the brew kettle and bottling pale? (with a properly sanitized hydrometer)
It does work, but I always think it's a pain. Maybe my plastic tube isn't as good as other people's, I don't know. Think I need to get an actual jar with a wide base or something. But yes, it does work :-)
Hydrometers are very fragile, and putting them in the kettle or pail puts the batch at risk if the hydrometer breaks. There are a couple of threads dealing with the brewer's agonizing decision as to whether to dump the batch or not, after the hydrometer breaks.
