Competing Interests

Funded by Anheuser-Busch InBev, Inc. and Monell Chemical Senses Center institutional funds. This does not alter the authors’ adherence to all the PLOS ONE policies on sharing data and materials. Regarding competing interests, the project was funded in part by AB-Inbev (as declared above). In addition, BB and PW have had previous funding to study carbonation sensation from the Coca Cola Company (though that project was not directly relevant to the current findings). BB and PW have also received honoraria from the Coca Cola Company to provide educational seminars on carbonation sensation (the topic of these seminars were not directly related to the current project). The authors have no other competing interests regarding carbonation perception to declare.
