A couple of weeks ago I wrote about Oxygen Transfer Rate (OTR), and how the type of closure can influence the quality of our wine long after it leaves the cellar. Of course the conditions chosen for bottle storage will also determine its evolution, meaning that the loft (attic) of your house is really not an ideal location, but then that’s another story…..

We have already established that Nomacorc is the best closure for our wine, and select the most suitable quality for our products no matter what the cost (synthetic is by no means cheaper than natural cork). However, in our constant quest for improvement, and with the help and advice from our friends at Nomacorc, we are now taking our cork expertise to the next level.

The new Nomacorc Select Series is available in three categories – not based on quality, but based on the density of the material. The differing densities have a significant influence on OTR, and therefore have a direct effect on how the bottled wine will evolve.

It would be easy for us to simply read the published statistics and to follow the recommendations of Nomacorc, but for such an important decision we have decided to make an analysis based on our own test bottlings. Under controlled conditions we have bottled three batches of the same wine, using the three different examples of the Select Series. Over the next 6 to 12 months we will pull corks at regular intervals, and then taste and analyse each bottle to determine how the three different corks influence the development of our wines.

If we discover that any one of the three works better than our current quality, then we will make the change. If there is no improvment then we will simply continue as we are, thus applying one of my favourite philosophies – if it ain’t broken, don’t fix it!
