Ok, my screen name ain't Screwy for nothing, let's just say over the past two weeks I've dedicated way too much time screwin' around with beer keg lines sizes, tubing lengths and trying my absolute best to get foam free pours. Hey, don't judge me.
Why bother you ask? Ok, well I bought some corny kegs and have found them
to be real time savers on packaging day, but taking those kegs to a party
requires a Co2 charge for dispensing the beer once you get there.
Oh and I bought an insulated cooling jacket complete with freezer safe gel
packs to keep the beer cold on the road, so I was invested pretty heavily into this whole idea already too.
Using a drinking water safe 5/16 inch inside diameter vinyl tubing between my Perl tap and
the ball lock on the kegs I was getting the perfect pour
every time at 7psi and loving it. But to my surprise getting the same quality
pour from a portable picnic tap was proving to be a major PITA! So
without further ado this is what I've learned after all this.
I eventually found out that using the same 5/16 inch inside diameter tubing, cut
to 48 inches long, with the same 5-7psi serving pressure the pours were
perfect every time. But surprisingly enough I also found out that when using a
picnic tap on the road I really needed to use a tubing with a 1/4 inch inside diameter, cut to 12 inches
long to get identical pours like the one at home!
The moral of the story is this, don't be afraid to experiment with any
aspects of brewing, from hot side to packaging and all steps in between for homebrewer''s like us there's really only one
way to find out what works best. Read what the 'pros' publish, use your
head and try different things, lots of times that's the only sure way
to find out what actually works best for you.
