Why is cork a good closure for wines?
Cork’s success over centuries lies in its unique physical properties that no man-made closure has been able to replicate: lightness, compressibility, elastic memory, gradual recovery, impermeability to liquids and resistance to wear, heat and rot.
Cork also allows a minute amount of oxygen to permeate into the wine after sealing. This appears to have a beneficial impact, but more research is needed to understand the full contribution of the cork to wine development.
In addition, the introduction of technical corks such as Twin Top, champagne corks and Neutrocork has extended the range of cork products available to suit each wine style and market segment.
With proper handling during and after bottling to ensure the best performance, cork is unsurpassed as a wine closure.
Do wines age just as well under screwcaps as they do under good quality cork?
It is a mistake to equate the best quality corks with screwcaps, which have a much stronger tendency to impart reduced characters to wine and restrict wine development.
While screwcaps may be suitable for some wines intended for quick drinking, very little is yet known about the impact of screwcaps on more complex wines intended for long-term cellaring.
Current thinking suggests that wines will develop more slowly under screwcap and may develop into different wines. They may never develop the characters winemakers and consumers appreciate in cork-sealed wines.
In those markets with greatest experience of screwcap, there is growing recognition that the issue of cork vs screwcap is far less clear-cut than screwcap advocates claim.
