How Wine Corks are Chosen
The choice to use cork as a closure for wine is something of a contentious debate. While there are many arguments in favour of a manufactured screw cap closure, or Stelvin Cap as it is known by popular trade name, there also exist many arguments against.
Blue Mountain continues to use all natural corks. This is partly due to the availability of top quality corks, and the increased quality of the cork available to us. It is also a style of winemaking that we feel has worked for us. Oxygen transfer, or lack thereof, into the bottle over time is a significant factor in how a wine ages over time, and we have reached a point where we know how our wines age in the bottle given the methods we have been using. A changeover to a metal screw cap would dictate a new approach to making our wines, and would also take time to understand whether or not we had made the correct choices in type of enclosure, type of glass, cap liner porosity, etc.
While there is certainly a place for the screw cap, we are sticking with the natural cork for our wines based on experience and testing over time. While we would never say never, at the moment there's just something satisfying about popping a cork. Call us old fashioned, but we like it that way.
What do you think? Do you prefer cork or screw cap?
