Ocean Water Sonic Copycat Recipe

Sonic's ocean water has been my go-to drive-thru order for years. When I figured out I could make it with just Sprite, coconut syrup, and blue food coloring, it was game-over. Two minutes, three ingredients, and you have the exact same sweet, coconutty, impossibly blue drink at home for a fraction of the price. This copycat recipe is almost too easy.

The Sonic Ocean Water Recipe You Can Make at Home

Sonic's ocean water has always been one of my favorite drive-thru orders. That sweet coconut flavor, the bubbles from the lemon-lime soda, that perfect blue color... there's nothing else like it. I ordered it so many times I started wondering what was actually in it.

Turns out it's three ingredients. Sprite, coconut syrup, and blue food coloring. I tested it at home and it tastes exactly like the real thing. The one thing that takes it from great to perfect is the pebble ice, and it's a big part of the Sonic experience. If you can get your hands on some. it makes a real difference. If you love copycat drink recipes like my Dirty Dr. Pepper and Harry Potter butterbeer, this one is your next obsession.

Ingredients

• 1 (2-liter) bottle Sprite or 7UP
• ½ cup coconut syrup (such as Torani, regular or sugar-free)
• 1–4 drops blue food coloring
• Maraschino cherries or raspberries, for garnish (optional)
• Pebble ice, for serving (recommended)

How to Make Ocean Water (Sonic Copycat)

Step 1: Fill with Ice

Fill a large glass generously with pebble ice; the small, chewable nugget ice that Sonic is famous for. If you don't have pebble ice, regular ice works just fine, but if you want the full experience it's worth getting.

Step 2: Add the Soda and Coconut Syrup

Pour the Sprite or 7UP over the ice, filling the glass about three quarters of the way. Add the coconut syrup. Start with the amount listed and taste before adding more since coconut syrup varies in sweetness and intensity by brand, so adjust to your preference. Torani is the go-to brand and is widely available, but any coconut simple syrup works great.

Step 3: Add the Blue Food Coloring

Add 1 or 2 drops of blue food coloring and stir gently until the color is evenly distributed throughout the drink. Start with one drop and add more if you want a deeper, more vivid blue. 

Step 4: Garnish and Serve

Drop in a maraschino cherry or a few raspberries if you'd like a little extra color and sweetness on top. Serve immediately while the soda is cold and fizzy. This ocean water drink is best enjoyed right away before the carbonation starts to fade.

Tips for the Best Ocean Water Sonic Recipe

Use Sprite or 7UP, not a generic lemon-lime soda. The clean, bright citrus flavor of Sprite or 7UP is what makes the coconut syrup taste the way it should. Off-brand lemon-lime sodas can taste flat or artificial in a way that throws off the balance of the whole drink. You can use Sprite zero or 7UP zero sugar if you want a sugar-free drink.

Torani coconut syrup is the closest to Sonic's. It has a clean, sweet coconut flavor that's not too heavy or artificial-tasting. The sugar-free version is a great option if you want a drink with less sugar and it tastes nearly identical to the regular version in this drink.

Start with one drop of food coloring. One drop usually gives you a beautiful, vibrant blue. Two drops deepens it further. More than two and it can start to look more purple than blue depending on the brand of coloring. Stir well after each drop before deciding to add more.

Make a pitcher for parties. Mix a 2-liter of Sprite with the full half cup of coconut syrup and several drops of blue food coloring in a large pitcher. Set it out at a party or summer gathering as your signature drink. It's one of the most visually striking drinks you can serve.

Taste and adjust the coconut. Some people love a more subtle coconut note; others want it front and center. The half cup of syrup listed here gives you a noticeable but balanced coconut flavor. Add more a tablespoon at a time until it's exactly where you want it.

How to Store This Drink

Ocean water is best made fresh since the carbonation fades quickly once the lemon lime soda is poured. Keep the unmixed ingredients on hand: a bottle of Sprite in the fridge, coconut syrup in the pantry, and food coloring in the cabinet, and you can make a fresh glass in under two minutes anytime. If you want to mix a pitcher to make it ahead, cover it and refrigerate for up to 24 hours. It'll lose some fizz but still taste great. Give it a stir before serving.

Frequently Asked Questions

What is Sonic ocean water made of?

Sonic's ocean water is made with Sprite, coconut flavoring, and blue food coloring. This copycat uses the same three ingredients to recreate that signature sweet, tropical, bubbly flavor at home with ingredients you can find at any grocery store.

What does Sonic ocean water taste like?

It tastes like a sweet, tropical, coconut-flavored lemon-lime soda. The coconut flavor is front and center but not overwhelming, the Sprite keeps it light and fizzy, and the combination is refreshing in a way that's hard to describe until you try it. It basically tastes like something you'd want to be drinking on the beach. 

What coconut syrup does Sonic use?

Sonic uses their own proprietary coconut flavoring but Torani coconut syrup is the most widely recommended at-home substitute and is considered the closest match. It's available at most grocery stores, coffee supply shops, and online.

How do you make Sonic ocean water without coconut syrup?

Coconut extract mixed with simple syrup is the best substitute. Use half a teaspoon of coconut extract per tablespoon of simple syrup and adjust to taste. Coconut water is another option for a lighter, less sweet version though the coconut flavor won't be as pronounced as the syrup version.

What is pebble ice and where can I get it?

Pebble ice, also called nugget ice or Sonic ice, is soft, chewable, small cube ice that's become iconic partly because of Sonic. It chills drinks more efficiently than regular cubes and is a big part of the Sonic experience. You can find bags at some grocery stores and gas stations, Sonic sells bags at the drive-thru, or you can invest in a countertop nugget ice maker if you want it at home.

Does the blue food coloring affect the taste?

Not at all, it's purely visual. The color is what makes ocean water so iconic and recognizable but it has zero impact on the flavor. Skip it if you prefer and you'll still have a great coconut lemon-lime soda, just without the signature blue.
