Moodybrew (Steve W) uses Bittburger 5-liter mini-kegs to keg his beer. I like the idea: They're small, they're cool, and they fit in the fridge.
Here's a pic of the hardware he uses to tap the mini-kegs.
And here's a pic of the Bittburger mini-keg bung.
I couldn't find Bittburger in Shreveport, so I bought a similar Heineken mini-keg and sucked up the $20.00 cost on the assumption that I could use the container to keg my beer. I don't like Heineken that much, but eventually the beer was gone.
Here's a pic of the Heineken tap parts.
And here's a pic of the bung. It looks similar in size to the Bittburger bung, although it's more of a crimp-cap arrangement.
I removed the bung and dip tube taking care not to damage the mini-keg. This is what the parts look like when they have been removed.
The first thing I noticed when I was washing out the mini-keg was that there's a white spray paint can looking thing glued to the inside bottom of the keg!
You can't get the thing out, so I sacrificed the mini-keg, and sawed off the bottom using my jig-saw and a metal cutting blade. This is what I found.
This thing looks very much like a spray paint can. There's some strange looking things under the cap.
When you shake the can, it rattles as though it had beads inside.
Here's a pic of the parts in disassembled state.
With evidence in hand I searched the net. Above is a pic of Heineken's pride and joy - the mini-keg carbonator!
Conclusion: Heineken mini-kegs are not reusable; don't bother to buy one unless you're really into Heineken lager.
There was, indeed, something in my beer.
