As one of the strongest supporters of the blow-off method
on this digest distribution list, I feel a responsibility
to answer Russ' questions. I recommend you use the largest
diameter tubing you can figure out a way to attach to the top
of the carboy. I have heard of numerous brewers using a
tubing close to 2" in diameter, shoved directly into the top
of the carboy. I bought a piece of 3/4" O.D. hard plastic
tubing and cut myself a 3" long piece. This (with great
difficulty) I stuffed into the hole in a rubber stopper that
fit the top of the carboy. I had to ream out the hole in the
stopper a little also. Next, I pushed on a 5/8" I.D. flexible
clear hose (about 3-4 ft. long) onto the hard plastic tubing
sticking out of the stopper. To use this apparatus, I pour
about 16oz of water into a gallon glass jug, push the stopper
onto the top of the carboy, and submerge the other end of the
hose in the water in the jug. I usually get about 1/2 gallon
or so of blow-off. I don't even bother to switch to a standard
airlock until I transfer to the secondary. As an optional
suggestion (something which I may soon implement myself), is
to use a 6 gallon primary, so I have 5 gallons in my secondary.
The I.D. of the 6 gallon carboy mouth may be bigger, so you
may want to check this before you buy your stopper. Oh, by the
way, I forgot to mention that I fill the primary to within 2"
of the top (topping off with boiled chilled tap water) to get
maximum blowoff. It is important to keep the hose clean as
the resins and hop particles are impossible to clean out of
the hose when they soak in and dry up.
I highly recommend this method and I feel that my beer tastes
much better since I switched to this method.
