Tips to keep opened wine fresh during holidays

WEST LAFAYETTE, Ind. – A Purdue University chemical engineering graduate is available to talk about methods of keeping opened wine bottles from going stale during the holiday season including replicating what wineries do when bottling wine to keep it fresh.

Ryan Frederickson, founder of ArT Wine Preservation, can provide tips about the various methods of preventing opened wine bottles from going stale because of oxygenation. The goal is to reduce the exposure of wine to oxygen through different methods, including:

  • Using a gas, such as argon, to displace oxygen in the bottle and act as a protective blanket over the wine.
  • Using a pump to pull the oxygen out of the bottle, leaving a partial vacuum.
  • Using a commercial wine preservation tool that allows oenophiles, or wine enthusiasts, to draw the wine out of the bottle without uncorking it.
  • Storing the wine in a smaller bottle where there is less air, slowing the oxygenation process, or dropping a bag of marbles into an opened bottled to displace air in the bottle.
  • Refrigerating a bottle of wine after opening it to slow the oxidation process.

Frederickson also has created a product that allows consumers to spray argon, a non-toxic gas, in opened wine bottles to keep wine fresh. The product is available at Amazon and other locations including his company website at:

The process is similar to what wineries do when bottling wine, but allows consumers to preserve their own wine.
