Here is my version of a mini keg set-up to serve home-made beer from 2 liter PET bottles or beer growlers.
It solves a few issues for lovers of home-made and craft beer:
- Beer going flat once the growler has been opened.
- Having to clean and fill 48 bottles to store your batch of home brewed beer
It allows you to use 2 liter pop bottles (PET) which is cheap or your glass growlers. Apparently you can get 3 liter pop bottles in the US. Or buy 6 litter PET bottles from Tap-a-draft. They use 38 mm caps, same as beer growlers.
You only need a few parts and it requires very little skill.
I assume you already have a CO2 tank and regulator
DON'T use this without a regulator set at less than 40 PSI !!
Step 1: Tools and materials required
- 7/32" drill bit
- Flexible plastic glue - suitable to glue Vinyl.
- 1/8" Internal diameter, 1/4" Outer diameter Vinyl tubing - at least 4 feet
0.17 ID, 1/4 OD will also work and it is easier to find - 1/4" ID, 3/8" OD Vinyl tubing - 1 foot
You'll find this at any hardware store and it cost less than $1 per foot. - 1/4" to 1/4" Push-to-Connect Union
You can get this on ebay - search for "Push to connect 1/4 union" - and look for the cheapest one. - Picnic tap
From ebay or your local homebrew shop - 1/2" Hose clamp (or use a Wire clamp tool - see here how to make your own)
