The bottom line is that for true Champagne preservation, Perlage is totally unique. This is not some semi-functional butterfly cap, or phony vacuum system that does nothing to stop the loss of effervescence. Perlage has a perfect, thoroughly tested reputation for quality; has no legitimate competition of any kind; is the only device endorsed by all of the top Champagne houses; is used in more than 1000 restaurants; eliminates all lost revenue waste from “flat Champagne”; creates great new revenue streams and pays for itself in a matter of days or weeks by building a strong “by-the-glass” program.
