Kegging and Draft Systems
Why Keg beer?
Kegging Pros:
Bottling Pros:
Ease of cleaning
Carbonation precision
No sediment – good for comps
Potentially lower long term costs
Easy 02 free transfers
Stainless - no light, no broken
glass, store with sanitizer
• Pour any size – growlers, pint,
• Lager and serve without transf.
Oxygen absorption by yeast referm
No kegerator maintenance
Good for small test batches
Bottles ready for competition
Easy to share
Less space required
Low cost to get started
Good for long term storage
Keg assembly and cleaning
• Keg
• Lid
• Poppet valve
• Liquid (out) post
• Gas (in) post
• Dip tubes
• Gaskets/o-rings
• Quick disconnects
• Brushes
• Gasket
• Keg lube
• Keg washer
CO2 Assembly
Hose clamps
Check for leaks!
• Store with distilled/StarSan or mix fresh
• Close and pressurize keg. Run liquid through
liquid out.
• Shake, sit upside down, shake again.
• Drain dip tube and empty upside down with
lid open.
• Spray posts with sanitizer.
Racking (standard)
• Limit oxygen exposure
• Flood keg with CO2 through liquid post, bleed
through poppet.
• Open keg lid, siphon beer.
– Avoid sediment, especially hops. Will clog dip tube and
liquid post/QD.
• Seat the lid: set to 10-12 PSI while pulling up on
the bail. Once the lid is sealed and held up by the
gas, set the bail of the lid.
• Purge 2-3 times. Check for leaks.
Racking (O2 free)
• Equipment: carboy cap, stainless dip tube, sealed bung
• Sanitize keg, seat the lid, flood with CO2.
• If cold crashing, use a sealed bung. Fill plastic bag with
CO2, cover carboy mouth, slowly remove bung.
• Attach carboy cap with stainless dip tube.
– No hop residue critical – optional screen filter
• Connect line to liquid out post (sanitize posts!).
• Connect gas. Be careful with pressure no more than 45 psi.
• Open poppet (monitor volume closely towards end).
• Purge 2-3 times. Check for leaks.
Carbonating techniques
• How much CO2 do I need?
• What are volumes of CO2?
• The temperature-pressure-time interplay.
Carbonating Techniques
Set it and forget it
Set and shake
Crank and shake
– Leave 24 pressure to equalize
– High risk of over carbonating
• De-carbonating - turn off CO2, pull the relief
valve, test, repeat
• CO2 gauge
Draft Line Calculations
• Line length calculations
– Longer line = more resistance = less pressure at tap
– Greater elevation change = greater resistance
• Picnic tap example
– L = (keg_pressure – 1 psi) / Resistance
– 3/16″ ID vinyl tubing = 3 psi/ft
– beer loses 0.5 psi/foot of elevation gain
– L = (keg_pressure – 1 – (Ht_feet/2)) / Resistance
More Draft Info
• Cold lines = less foam
• How to poor: full open, full close
• Cleaning and replacing lines
• Keg jumping
• Filling growlers/bottles – silicone tubing,
growler filler, bottling gun, CPBF
