Every year, hundred millions of bottles of wine that have been affected by the chemical compound trichloroanisole or TCA (a fungus that forms on the surface of the cork) are tragically poured down the sink. This condition is more commonly known as 'cork taint', and can only happen to cork-sealed wine bottles.
Aluminium closures with the correct choice of liner provide a perfect seal, preventing any liquid leaking and stopping any other flavours getting into the wine.
When it comes to recycling aluminium, the possibilities are endless. In fact, your wine screwcap is very probably produced from aluminium products that other people have put into the recycling bin including other screwcaps!
