Dodgers and Giants. Yankees and Red Sox. San Pellegrino and Perrier. These are the greatest rivalries known to man. While it is clear to most that the Dodgers and Red Sox are the superior of the former two rivalries, it is not quite as apparent why San Pellegrino trumps the latter. Aside from the fact San Pellegrino has perfect bubbles, there is something else that sets it apart from its French competitor. Simplicity. Aranciata, Limonata, Sanbittèr, Pompelmo, Aranciata Rossa, and Chinò may use (and advertise) San Pellegrino as their primary ingredient, yet it is made clear that they are sodanot sparkling water. Perrier, however, comes in five flavors: Plain, Lemon, Citron-Lemon, Lime, and Pamplemousse. All are wonderful flavors, yet here inlays the issue. By marketing them as flavored sparking water, Perrier loses all of its credibility. Remember, sparkling water is about simplicity, and this is exactly what San Pellegrino does. Rarely running ad campaigns, never changing the bottle, and keeping their product simple, they rely on the quality of their product, retaining a loyal fan base and remaining puritan. Perrier, while never changing its tear drop bottle, by running excessive ad campaigns, and marketing their flavored variants, have aligned themselves with glamor…the antithesis of what sparkling water is about. So next time the San Pellegrino-Perrier debate arises at the market, think about whether you want sparkling water, or disgraceful carbonated water.
