Got one of those 5-litre kegs; does the beer need to be consumed quickly after opening? Or can you have a glass every now and then, drinking it over a matter of weeks.
I heard somewhere that it stays fresh for 30 day after opening.
I should probably check the leaflet that came with the keg; can't seem to find it right now.
Unless you're dispensing it with CO2, it will start to oxidize immediately. I notice a difference the day after opening one. Two to three days later it would be disagreeably oxidized. I suspect in thirty days it would be souring. Then again, if it takes you thirty days to drink a 5-liter minikeg (the math is easy; that's a mere ten 1/2-liter servings) perhaps you should consider buying beer in smaller containers.
Any time I buy one of the Party cans, I always finish it off in 2 days max because it's a fun way to dispense beer. Also, the beer seems to taste better than their bottled cousins...
I saw a big display of these things the other day (on the floor, so I'm also assuming they're not true "draft", non-pasteurized- "keep refrigerated" mini-kegs). They certainly look a lot more complicated that the various old gallon/5 liter kegs. I was surprised that the display had no literature/explanation of the system involved and the "leaflet" was stored under the blister-pack "lid", so I couldn't read it. Was there really no other explanation that "some sort of patented technology" ?
Some US breweries in the mid-60's came out with a gallon can

These used an separately purchased, re-usable clamp-on tap that used disposable C02 cartridges (not shown in photo).
Falstaff once sold a true 2 gallon "mini-keg" -

And, of course, many German beers now come in 5-litre cans that are simply gravity poured.
Indeed, the best I've found is that from Br. Krug in Breitenlesau, sold at the bottle shop around the corner (I forget--maybe 8EUR?):

That's old, though--they now have their own printed cans, with their logo covering the whole thing, instead of a bottle label slapped on a generic one like in the Foto (note "0,5L").
