  Evan Wallace here, the designer of the Perlage System (and possibly biased ;). The most visible difference between the two products is that Perlage has a shell around the entire bottle and Coravin does not. The purpose of the shell is safety. Pressurizing a glass bottle is inherently dangerous; if a pressurized glass bottle exploded in front of a group of customers, the results would be catastrophic. Lawsuits would abound. In the unlikely event of a bottle spontanously breaking, or more likely being banged against the edge of the bar and breaking, the safety shell of Perlage would catch all the glass shards in the enclosure. Because of this safety feature, we can confidently pressurize the bottle to the exact pressure that Champagne is produced at, around 60 PSI, whereas Coravin cannot. Thus, Champagnes preserved with Perlage show zero change over time, whereas Coravin will see a decrease in dissolved CO2, and hence less effervescense over time.
