The design of bottle caps and wine bottle corks have changed very little over the last 50 years and they have done their job very well indeed. Indeed they are an iconic image to the seasoned drinker, scattered about the floor and table after a heavy night on the liquor. However, now that more advanced version of bottle top such as the screw top have come on the scene, it looks like its curtains for the classics.
Bottle caps are traditionally made from steel and the original design had 24 teeth that wrapped around the rim, although more modern caps have around 21 teeth. Whilst they were great at keeping the contents of a bottle fresh, they are a nightmare to get off and unless you have teeth made from granite, you have to use a bottle opener to stand any chance of quenching your thirst. For this reason above all others, the screw top beer bottle has seen an upsurge of popularity in recent years, as they can be taken anywhere and you don't have to drag and bottle opener along with you.
The case is pretty much the same with wine bottle corks, but there are a couple more reasons why corks are being pushed out (no pun intended). A corkscrew used to be a staple part of any tableware set, but its usefulness is dwindling as screw top wine bottles become more popular. In the same way as beer bottles need a bottle opener, wine bottles always required a corkscrew to be close by, and that’s just not always practical. Furthermore, corks are not as good as screw tops for wine storage. Air can breach the cork as it expands and contracts with different moisture levels in its surroundings, and air can very easily turn a wine bad. Also, it has a tendency to break up over time if the wine is stored horizontally, as it often is on wine racks, resulting in the wine sometimes being ‘corked’ when served. So it seems that whilst some classic tops are on their way out, at least they are being replaced by superior products.
