While screw caps still have a bit of a bad reputation, in our opinion, it’s undeserved. But do wines with screw caps age as well as wine with corks?
Screw-caps and everyday wine
Imagine you’ve bought a bottle of wine and maybe you’ve kept it for a few years. What do you care about? Probably the topmost question in your mind is ‘Does it still taste good?’
In all probability, a screw cap bottle will keep its freshness just as well as a cork bottle. Perhaps better.
Indeed, that’s why many Australian and New Zealand producers, even high-quality producers like, use screw-caps.
They reckon it preserves the freshness of the fruit and it avoids the risk of cork taint from a faulty cork. Although this is less common than it was, it still affects.
In the past, screw-caps were sometimes too airtight and this resulted in reductive aromas from newly opened bottles. But newer screw-cap designs allow some oxygen transfer, avoiding this problem.
Screw-caps vs tradition
There is a lot of tradition in wine and many winemakers aim to emulate the classics, especially if they want to charge a premium price. This includes choosing corks over screw-caps.
Certainly for, we ended up with a selection that was all cork-sealed. Not out of prejudice, but because we wanted a high-quality selection and all our producers have all gone down the cork route.
Screw-caps and age-worthy classic wines
Whether there’s a difference in quality in the long run is harder to say. My personal view is that for wines that you might keep 5–10 years, a screw-cap probably won’t be any worse and might be better than a cork. Beyond that, the jury is still out because of the small sample of properly old screw-cap bottles.
No doubt, the great French houses have libraries of test wine in their cellars with screw caps to see how they age over the years. But nobody has opened a 50-year-old Burgundy or Bordeaux with a screw cap to see how it’s aged because, well, there aren’t any. Yet.
