Screw caps vs Corks- One photo sums it up

Top Row: The same wine, aged 28 months under a number of different closures. From left to right: Far left- Screwcap, all others are various forms of cork closures.

Bottom Row: The same wine, aged 10 years under a number of different closures. From left to right: Far left- Screwcap, all others are various forms of cork closures.

The far left wines remain their original, healthy colour, while the corked wines take on oxidative, browning colours. (Not good)

Thoughts?

    The evidence is clear. Screwcaps are superior to corks in preventing wine spoilage in bottles stored up to 10 years. I have never found that corks enhance the quality of wine, Occasionally, corks ruin the wine experience to various degrees. Brittle corks can break during the removal process putting cork crumbs into the wine. Some allow leakage and mold to form. I now prefer screwcaps for the ease of removal and the simplicity of resealing the bottle for another day’s use.

    Does this mean the screw capped wines will not benefit from aging or that the possible negative effects of aging the wine are inhibited?

  3. Wine ages anerobically, meaning it ages without the presence of oxygen. Therefore, a screwcap, which provides an oxygen free environment for the wine, will allow the wine to age naturally in the bottle. Compared with a screwcap, using cork increases the risks of oxygen exposure to the wine and opens up TCA faults also. It’s not to say that cork isn’t an acceptable closure, rather that screwcaps have dramatically lower fault issues in comparison.
