When asked about the violet beverage via email, a Starbucks spokesperson said the company is always thrilled when customers create all-new beverages that aren't on the menu. Just a few weeks ago, a "Pink Drink" similarly took over Instagram.
"Our customers are always trying out new ways to customize their favorite drinks -- Purple Drink is a perfect example of that!" the company said in a statement. "We’re blown away with the reaction on social media -- while this isn’t an official Starbucks drink, it’s created a lot of fandom online. If customers would like to order a beverage that is not listed on our menu, we recommend they know the recipe so that their barista can handcraft the beverage perfectly for them."
With that said, you probably shouldn't walk into your local Starbucks and expect anything less than eye rolls when you attempt to order a "grande Purple Drink." Anyway, here are a few more photos of the beautiful lavender-colored drinks from Instagram:
