I know why they are used for the OG/SP and to tell when fermentation is done plus figuring out your alcohol % but if everyone says to just let it primary for a month or longer and you dont care to know then FG then do you really need to do it. Maybe for bigger beers but just let it sit two months. I still use one but I have a beer that I made on 1/1/11 and want to transfer it to a keg tonight, I assume its done fermenting. I did take a gravity reading today but it was beer with alot of trub because my primary has a spigot. So this throws off my FG with all the solids in solution. I dont have a wine theif so was wondering if I leave it on primary for a 3-4 weeks then do I really need to take a hydro reading?
