Beer preservation system?

Discussion in 'Beer Talk' started by PeterJ, Mar 15, 2013.

  1. I've seen and used a few good wine preservation systems, even some that keep Champagne fresh and bubbly. Has anyone seen a system that will keep an open bottle of beer carbonated for extended amounts of time?
  2. Extended time? If it's bottle conditioned simply add a little sugar to the beer and seal the bottle , it will recarbonate over time.

    The best preservation system is not having to preserve a beer.

    If you open a bottle that you are not intending to finish you are accepting the fact that the condition of the beer will deteriorate noticeably. Either from loss of carbonation or oxidation it is simply better to consume the beer with in a reasonable time frame after opening.

    What you need is a large, pressure capable steel bottle with a gas input tube and an output tube for beer which draws from the bottom. This way you can keep the beer in an oxygen-free environment and still dispense the beer. Beer packaged this way should last quite a long time.

    The time frame differs from beer to beer. I have used rubber wine stoppers before and kept a beer carbonated with no "noticeable" difference for a couple days. After that you are really pushing it. I would say the bottle should be at least half full if you plan on reserving it, otherwise it will go flat much sooner.

    I disagree regarding the no noticeable different part. I have been forced to cap a beer with a rubber wine stopper and even the next day the difference is more than negligible. The beer is still acceptable and drinkable but its not the same beer. I think different beers can handle this better than others. Big stouts and barleywines do not need big carbonation to hold up.

    Only my opinion based on my experience. The only way to find out what works for you personally in experimentation. I certainly wish I had the same luck with beer holding up with no drop off for a couple days.

    This is one of my favorite posts I've ever read.

    Drink your damn beer. There are thirsty people in Africa with nooo beer in sight. Well, they may have beer, but it's probably not very good.

  9. I don't know about your time scale but it's been common practice here in bars to use 2 litre PET bottles of lemonade (like your 7-up) and once opened the caps don't go back on again. The carbonation remains perfectly acceptable for the rest of the day.
    As for oxygen, how does it get in, and even if it does how much will there be? The entire system in a bottle is of a CO2 atmosphere and a CO2 generator (the gas dissolved in the beer)....any air that does get in will be purged by the heavier CO2 coming out of solution which will form a blanket over the beer.
