Because the cork stoppers in wine bottles can leak, crumble, or become moldy, winemakers must often discard a significant proportion of their inventory of bottled wine.
Bottlemasters, Inc., produces a plastic stopper that cannot leak, crumble, or mold. Bottlemasters’s plastic stopper is available to winemakers for a price only slightly higher than that of traditional cork stoppers, and
cork prices are expected to rise considerably in the near future. Therefore, the Bottlemasters plastic stopper will most probably increase its share of the market for wine-bottle stoppers.
