For hundreds of years the cork stopper was wine’s saviour - keeping it in the bottle and the harmful gas out.
The introduction of the cork is down to the Benedictine monk Dom Pérignon who saw the great qualities of cork as a closure and replaced the then standard wooden stoppers wrapped in hemp and soaked in olive oil and bunged tightly into the barrel’s opening.
And so for centuries cork was the closure of choice. But then scientists discovered the problem of corked wine where what comes out of the bottle tastes musty.
The problem was caused by a tainted cork contaminated by the chemical compound 2,4,6-trichloroanisole, or TCA to you and me.
A badly corked wine will have a characteristic damp, moldy cardboard box smell. Believe me, you will recognise it as soon as you smell it. It will be undrinkable but harmless if you do.
The realisation that their industry was in danger of sinking gave cork manufacturers a massive hygiene wake-up call and conditions, particularly in Portugal, have improved immeasurably.
While all this was going on the screwcap entered the market and the great cork versus screwcap debate began, and continues remorselessly.
Tainted corks are still around. At one stage as many as 10 per cent of bottles were affected. That figure has been cut to about 2-3 per cent in recent years.
The number of screwcap bottles on the shelves has grown dramatically. But in recent times screwcaps have been found to have a problem - reduction.
It happens when sulphur compounds build up in the neck of the bottle because of the lack of oxygen. In extreme cases the wine can smell and taste of sulphur.
So you choose your closure and take your chances - and the battle for the hearts and minds of the consumer is in full swing with the Portuguese Cork Association signing up no less a person than soccer coach José Mourinho to be their roving ambassador!
