CORKWATCH is an app from ReCork that lets you know which wines use REAL corks (good!) versus those ugly plastic corks(bad!). It also allows YOU to add new wines to the list. The site is compatible with all mobile devices and super intuitive.CORKWATCH also has a searchable database and map that allows you to find a drop off location for corks in your area. Most Whole Foods will also accept real corks...as will Firefly restaurant in DC (and you can just drop them off there..you don't have to stay for a meal - though you should as the food is sustainably sourced and fab!) For more information as to why you should opt for wines with cork stoppers, check out the WWF Report, "Cork Screwed?"
