Occasionally, you may come across a wine bottle that has a wax seal over the top of the cork that somewhat covers the neck of the bottle. You may have wondered “Why is it sealed in wax?” and “How do I remove the wax so that I can get to the cork?” These are a couple of great questions to explore.
Most wine bottles today have a capsule cover the cork that goes part-way down the neck of the bottle. In the not so distant past, these were made from lead but are now manufactured from aluminum or a heat-shrinkable plastic.
Whatever the material, these wine bottle capsules serve several purposes. Originally, a capsule was used to protect the cork from insects and varmints when being transported by ship or being stored in caves. And, wax was sometime used as a seal over the cork to keep it from leaking.
With today’s availability of good quality cork, plastic corks and twist-off caps, it’s generally not necessary to add a wax seal. But, some wine producers do use it. Today the wax is used to either provide an air-tight seal for wines that are meant to be aged for long periods of time or they are used as ‘high-end’ decoration for otherwise ordinary wines.
So, these wax seals can either be functional or decorative. But, how do you get through the wax to be able to pull the cork? We’ll address that next time. Until then, Cheers!
