Some of the first adopters of the twisties were white wine makers. Once opened white wine has a longer shelf life than red wine and if re-capped and stored in the refrigerator, can be drunk up to a week or more after opening. Once opened every bottle of wine is exposed to oxygen, at first this aeration will enhance the wine's flavor. However if the bottle is not consumed at one sitting and is re-corked with its cork wine stopper, the oxygen will continue to work on the wine through the permeable cork. Using a metal cap decreases the changes in flavor caused by aeration over time thus allowing white wines to be drunk over a number of days.
Nevertheless, some people dislike the taste of wines with a metal twistie and prefer wines sealed with cork.
It may be humble but a twist off cap also means the ullage doesn't grow during storage, which means more wine for you and all those billions of Chinese wine fans.
So the debate over which is better—cork vs. twist off—is irrelevant. Winemakers choose the best sealant option for their wines and business. So it's not cork or twistie, it's cork and twistie.
And that's what really matters: getting the best bottle of wine U can, U know?
