Natural Cork Makers Unite

For hundreds of years, wine-makers have used natural cork – made
from tree bark – to seal their bottles. But natural corks are… well,

wine-makers are switching to synthetic corks – made of plastic – as a
solution. But right now, they only make up about one-percent of the
market. Nevertheless, natural cork manufacturers are taking action.
