Wine corks from Berlin Packaging can prevent excess air from affecting wine during aging periods. Traditional wine corks are made from natural cork and can keep wine fresh in storage for up to eight years without deteriorating. Colmated corks provide similar benefits. For wine that needs to undergo long-term storage, adding wine shrink caps can help protect the cork from deterioration. Other wine seals and caps include plastic corks and stoppers, and metal screw-caps for threaded bottle heads.

Choosing a Closure for Wine

Natural cork has long been the standard for wineries to use to cap wine bottles, as they have proven to help in the aging process. However, other options like standard colmated corks have been developed and can provide almost identical benefits and lifespan. Colmated standard corks use cork dust to fill in air spaces in natural cork. They can also form to the shape of a wine bottle neck, and provide a smooth outer finish.  

Wine Shrink Caps to Protect Corks

Standard and plastic wine corks also help keep air from creating a flat taste due to air exposure. Using the right corks and stoppers can save wine from cork residue, and help keep gases and moisture from affecting the quality of the wine. To protect corks from breakdown during long-term storage, many wineries use wine shrink caps. When considering shrink bands to cover plastic, natural, and colmated wine corks and screw-caps, look for color choices for function and style. Some versions, like black wine caps, have tear tabs to make wine caps easier to remove.

Bottling Tools for Corking Wine

Sealing homemade or small batches of wine in bottles with handheld wine corkers helps ensure corks are tight, and leak and air-resistant. Air-tight seals help prevent sour tasting, oxidized wine. Depending on the type of closures you choose, you may also require a manual thermal PVC capsuling unit to protect natural and colmated corks.
