Does the type of cork matter?
Not so much. There are three types currently in general use, metal cap, synthetic (plastic) and natural cork. All three will keep a wine in a bottle. Metal capped wine is destined to be drunk relatively soon, within a year, synthetic corks sometime after a year and natural cork tend to be for wine that could be put up for a long period of time. This site probably won’t report on too many of those. Metal capped and synthetic corks try to reduce a “corked” wine, one that went bad because of the cork itself.
