What's really funny is that some good wine is being bottled with screw caps.
I tasted some Red Pillar from Australia that came sans cork.
Not bad, and not expensive.
When profit margins are low, loss from corks becomes more important. Some vintners are looking at fifteen percent loss because of bad closures. Screwtops are the wave of the future, like them or not.
Cork ... except for top of the line champagne is going the way of the dodo bird. Plastic and screw top are the wave of the future for wine bottles. Most wine, the least expensive (which is the most popular), is consumed within a year of bottling ... so why waste money on cork? The quality of wine which is of short duration (much of it very good) isn't adversely effected by the fact it isn't a corked bottle.
Gimme my 5L. moonshine jug of Gallo Blush, and I'm good to go for the night. Really.
