Re: Homebrewing Beer
TAB your assumption is correct. An air lock is used for secondary. I use the S-shaped ones rather than bubblers. Simply because they are one piece, no parts to use. Do not get in a hurry to trasfer to secondary. If you have a hygrometer you will be looking for specific gravity of less than 1.020, I shoot for 1.015. If you do not there are visual signs of complete primary fermentation; of course no CO2 comming out of the blow off, the wort will become darker as the yeast falls out of suspension, the top foam layer will fall, a layer of dead yeast will form at the bottom over 1/2" thick.
If you come off primary too early you can end up with beer that has a butterscotch flavor because diacetyl isn't converted by the dying yeast (not good beer). Other risk is gushers. Bottles that foam continuously because of too much pressure. In brewing patience is always rewarded.
