Berry Monsoon

Berry Monsoon is a Franchise Exclusive Mountain Dew flavor available since May 2018 only at Sam's Club stores.


Berry Monsoon is a Berry Lime flavor of Mountain Dew that is Blue-Green in color, very similar to Game Fuel (Berry Lime).

It was reported that the flavor is identical to 2015's Game Fuel Berry Lime in terms of color and flavor. The key difference is that Berry Monsoon is sweetened with sucralose and acesulfame potassium along with high fructose corn syrup to reduce calories.


Its tagline is "DEW with a Storm of Berry Lime Flavor."


In March 2018, Mountain Dew Berry Monsoon first appeared on the official PepsiCo Beverage Facts website. The website indicated that this flavor would only be exclusively available to Sam's Club store locations in the United States.

On May 2nd, 2018, in a Reddit post, it was leaked that "asiansteev" posted an image of Berry Monsoon in a soda fountain, showing that Berry Monsoon was released in his local Sam's Club, marking the beginning of Berry Monsoon being released in Sam's Club locations as a permanent flavor.

2019 replacement rumors

On July 7th, 2019, in a r/MountainDew Reddit post, a PepsiCo employee named u/G-Up had claimed that Citrus Cherry would replace Berry Monsoon as the new Sam's Club exclusive drink. The time came and went, with this rumor not coming to fruition and Berry Monsoon remaining as the exclusive flavor.

Berry Monsoon Zero Sugar

In November 2020, a listing on the official PepsiCo Beverage Facts website was discovered of Berry Monsoon Zero Sugar, however it did not show a render of the drink. Fans were skeptical if this would become available or not.

On April 17th, 2021, a render was added to the listing, confirming that it would be coming to Sam's Clubs in the near future. Berry Monsoon Zero Sugar was later discovered as early as July 31st, 2021.


  • Berry Monsoon is the third berry lime flavor that has been produced in the Mountain Dew lineup, the first being Triple Berry, and the second being Game Fuel (Berry Lime).
  • According to the nutrition facts, Berry Monsoon has an almost identical formula listing to Game Fuel (Berry Lime) with only a few minor differences. This was also the case with 2019's Cyclone and 2013's Sangrita Blast, two very similar Citrus Punch flavors.
  • Berry Monsoon was leaked and released exactly two years before Atomic Blue's release.
  • Berry Monsoon is one of the first much earlier Franchise Exclusive flavors before the Franchise Exclusive flavors became a prominent staple of Mountain Dew's lineup in recent times.
