I have a Russian Imperial Stout in my plastic fermenter. The local brew shop operator discouraged me from buying a hydrometer when I tried to purchase one. I will get one and I will also find a new place to buy my ingredients. I used liquid yeast and within 24 hours I had lots of action. My airlock was bubbling so hard that wort and foam were coming out of it and around the sides of the lid where it is supposed to seal. After about 3 days the bubbling subsided. Since I did not get a reading with a hydrometer on my wort...is there any reason test it now? Without a base line can I determine ABV? I will rack this into my carboy tomorrow. Should I get any activity from my airlock in the carboy? My local guy says the time in the carboy is more of a settling process. I want to get the most out of this brew. Any suggestions?
