Sodastream to test Pepsi brands

A regulatory filing with the Securities and Exchange Commission verifies the report from Beverage Digest. In the filing, Sodastream said it has entered into an agreement with Pepsi for a “small-scale, limited time test” to see how the beverage maker’s brands sell on Sodastream’s beverage making system.

The company said it expects to conduct the limited test “later this year.” In addition, Sodastream said it continues to explore “multiple relationships with other leading beverage brands.”

Sodastream emphasizes the word “limited”

In the regulatory filing, Sodastream emphasized that the test on Pepsi’s brands is only limited at this time and that there are currently no plans to expand its partnership with the soda maker. The company also said it will not comment on any speculations or rumors regarding how the partnership is going.

Today’s filing does not indicate which of Pepsi’s brands will be released on Sodastream’s home beverage making system. In addition to the Pepsi brand, PepsiCo also sells Sierra Mist and Mountain Dew.

The test will last only ten weeks and will include some “naturally sweetened” options that currently being sold in retail locations, like “Sierra Mist Homemade” and “Pepsi Homemade.” Beverage Digest gave the following list of flavors, according to Business Insider: Sierra Mist Homemade Cranberry, Pepsi Homemade Wild Cherry, Sierra Mist Homemade Peach and Pepsi Homemade Vanilla.
