New Starbucks Summer Skies refresher

Hi! Is the new Starbucks Summer Skies refresher drink Kosher?
Thank you!

Not kosher. Grape juice is a problem.

Thank you!

Are the pearls that come with the drink kosher? They let you add that to other drinks…

Raspberry Flavored Pearls [Water, Sugar, Calcium Lactate, Sodium Alginate, Vegetable Juice Concentrate (Sweet Potato, Carrot), Citric Acid, Xanthan Gum, Natural Flavor, Calcium Chloride, Potassium Sorbate].

Thank you!

Kosher
