What Does the Blue Coconut Refresher Taste Like?

This drink tastes like the Strawberry Acai Refresher had a tropical vacation — sweet, fruity, and bright with a subtle coconut sweetness woven through every sip. The strawberry and acai base is tangy and refreshing, and the coconut syrup adds just enough tropical flavor to make it feel like something completely new.

The blue spirulina adds absolutely zero flavor — it's purely there to give this drink that stunning, electric blue hue that makes it almost too pretty to drink. It's light, refreshing, and not too sweet — basically everything you want in a summer drink.

Why You'll Love This Copycat Blue Coconut Refresher

• Cheaper than Starbucks — New Starbucks summer drinks come with a premium price tag. This homemade version gives you the same stunning drink at a fraction of the cost!
• One batch makes 5 drinks — The homemade Strawberry Acai base makes 2½ cups — enough for 5 full refreshers. Meal prep your summer drinks and thank yourself all week!
• That electric blue color — It's absolutely show-stopping. Whether you're making it for yourself or serving it to guests, this drink is guaranteed to turn heads.
• No artificial dyes — That gorgeous blue comes entirely from natural blue spirulina powder. Beautiful AND clean!
• Caffeine-free — Unlike most Starbucks drinks, this refresher is completely caffeine-free. It's perfect for kids, non-coffee drinkers, or anyone who wants a gorgeous summer drink without the buzz.

What is Blue Spirulina?

Blue spirulina is a natural pigment derived from blue-green algae, and it's the magic ingredient behind that jaw-dropping electric blue color in this refresher. It's the same ingredient we use in our Blue Coconut Matcha cold foam — and just like there, it adds zero flavor here.

It's completely safe, widely used as a natural food coloring, and packed with antioxidants and anti-inflammatory properties. You can find it at most health food stores, here on Amazon, or at Whole Foods — and just ⅛ teaspoon is all you need for that stunning blue hue!

Ingredients Needed

This Blue Coconut Refresher comes together in two parts — the homemade Strawberry Acai Refresher base and the refresher itself. Don't let the ingredient list intimidate you — the base is simple to make and gives you enough for 5 gorgeous drinks!

• Water and white grape juice — The liquid base of the refresher. White grape juice adds a subtle sweetness and helps create that authentic Starbucks flavor.
• Fresh strawberries — The star of the base! Fresh, hulled strawberries give this refresher its bright, fruity flavor and beautiful color.
• Granulated sugar — Just enough sweetness to balance the tartness of the strawberries and lemon juice.
• Acai powder and passionfruit powder — The secret ingredients that give this base its authentic Starbucks Strawberry Acai flavor.
• Lemon juice and citric acid — Together they add that bright, tangy, slightly fizzy-feeling brightness that makes Starbucks refreshers so addictive.
• Coconut syrup — The tropical twist that transforms the classic Strawberry Acai into the Blue Coconut Refresher. Sweet, tropical, and absolutely dreamy.
• Blue spirulina powder — Just ⅛ teaspoon gives this drink its stunning electric blue color!

Substitutions

• No fresh strawberries? Frozen strawberries work great instead!
• No acai or passionfruit powder? These are worth tracking down for the most authentic Starbucks flavor — you can find both on Amazon. You can make it without them and still have a delicious drink, but you won't have that signature Starbucks taste.
• No coconut syrup? Use 1 ½ tablespoons of simple syrup plus ⅛ teaspoon of coconut extract for the same sweet coconut flavor.
• No citric acid? Add a little extra lemon juice instead. The flavor won't be quite as bright, but it'll still be delicious!
• Want to mix it up? Swap the water for lemonade to make a Blue Coconut Lemonade, or swap it for coconut milk to make a creamy, dreamy Ocean Drink. So many fun variations!
• Using the store-bought base? Simple pour 1 cup of the mixture into your cocktail shaker, then add 1 tablespoon coconut syrup and ⅛ teaspoon of blue spirulina and shake!

How to Make the Blue Coconut Refresher

This recipe has two parts — first you'll make the Strawberry Acai Refresher base, then you'll shake up your refresher. The base takes about 15 minutes and makes enough for 5 gorgeous drinks, so the hard work pays off all week long!

• Step 1 — Add the water, white grape juice, fresh strawberries, and granulated sugar to a medium saucepan and stir to combine. Heat over medium heat until it reaches a simmer, then simmer for 10 minutes.
• Step 2 — After 10 minutes, strain out the strawberries, squeezing them firmly to get as much liquid as possible. Discard the strawberries and pour the liquid back into the saucepan.
• Step 3 — Heat the strawberry liquid over low heat and whisk in the lemon juice, acai powder, passionfruit powder, and citric acid. Whisk until everything is dissolved — note that the acai powder will leave small specks; this is totally normal and expected!
• Step 4 — Remove from heat, transfer to a large jar, and allow to cool completely before using. Don't rush this step — a warm base will melt your ice and water down your drink!
• Step 5 — Add ½ cup of the cooled Strawberry Acai base, ½ cup water, 1 ½ tablespoons coconut syrup, and ⅛ teaspoon blue spirulina to a cocktail shaker or mason jar with a lid. Shake vigorously until well combined and the blue spirulina is evenly distributed. Pour over ice and drink up!

How to Use the Strawberry Acai Refresher Base

Since this base makes enough for 5 drinks, why not get creative with it? Here are some of our favorite ways to use it beyond the Blue Coconut Refresher!

• Classic Strawberry Acai Refresher — Skip the coconut syrup and blue spirulina and just shake the base with water and ice for the Starbucks classic.
• Strawberry Acai Lemonade — Skip the coconut syrup and blue spirulina and shake the base with lemonade instead of water for a bright, tart, incredibly refreshing summer drink.
• Pink Drink — Skip the coconut syrup and blue spirulina and shake the base with coconut milk instead of water for a creamy, dreamy Pink Drink moment.
• Blue Coconut Lemonade - Shake the base with lemonade instead of water!
• Ocean Drink - Shake the base with coconut milk for a creamy blue drink!
• Summer Popsicles — Pour the base into popsicle molds and freeze for a fun, fruity summer treat the whole family will love!

Tips for the Best Blue Coconut Refresher

• Let the base cool completely. This is the most important tip! A warm base will melt your ice instantly and leave you with a watery, diluted drink. Let it cool fully — even refrigerate it overnight if you can!
• Shake vigorously. The shaking is what distributes the blue spirulina evenly throughout the drink. Give it a really good shake for that consistently beautiful blue color in every sip.
• Use lots of ice. Refreshers are best served ice cold. Fill your glass to the top!
• Batch prep your base. Since the base lasts up to a week in the fridge, make it on Sunday and enjoy gorgeous blue coconut refreshers all week with almost no effort.
• Adjust the coconut syrup to taste. Love a stronger coconut flavor? Add an extra half tablespoon. Prefer it more subtle? Scale back slightly. This recipe is totally flexible!
