Blue Lagoon Energy Cooler (Energy Drink Version)

One naming note before anything else: “Blue Lagoon” is a generic, decades-old mocktail name — blue curaçao syrup, lemon-lime, and soda, traditionally — the same category of public-domain drink name as a Shirley Temple or a Moscow Mule. It isn’t a trademarked menu item owned by any single coffee chain or brand, which is why we’re comfortable using it directly. This version swaps the traditional soda for a sugar-free energy drink, matching the caffeine-drink pattern of our other Energy Cooler recipes, and it has zero alcohol — both the syrup and the juice are alcohol-free.

Make the Syrup First (Just Once)

This recipe assumes you already have a jar of Blue Curaçao Syrup in the fridge — it keeps about 2 weeks and covers many drinks. If you haven’t made a batch yet, go do that first, then come back here.

Building the Drink

1. Fill a 16oz glass with ice.
2. Pour in 2oz lemon juice and 2 tbsp of the blue curaçao syrup, stirring to combine.
3. Top with 8oz sugar-free energy drink, poured gently.
4. Stir once more and serve.

Sugar-free energy drink (8oz portion of a 12oz can)~130mg

Caffeine, this drink~130mg

That’s a single, ordinary energy-drink dose — roughly a strong double espresso shot’s worth, and nothing stacked on top of it, unlike our caffeine-boosted or nitro-plus-energy-drink builds.

Drive-thru blue/specialty-flavor energy drink (16oz, tax included)~$6.75

Home version (energy drink, syrup, lemon juice)~$1.82

Savings per drink$4.93

Assumptions: a 16oz drive-thru specialty-flavor energy drink (representative pricing, varies by region/chain), a single 12oz sugar-free energy drink can, our own Blue Curaçao Syrup batch cost, and bottled 100% lemon juice at typical grocery pricing. At 5 of these a week over the site’s standard 48-week year, that’s roughly $1,183/year back in your pocket versus buying it out.

Swaps & Notes

• Prefer lime instead of lemon? A straight swap — 2oz lime juice works identically in the math and is arguably closer to some classic Blue Lagoon recipes.
• Want it less sweet? Drop to 1 tbsp of the blue curaçao syrup — it still gives you real color and flavor, just less of both.
• Buying energy drinks by the case usually brings the per-can cost down 10-15% from the single-can price used above.
• Prefer a plain orange version instead? See our Orange Energy Cooler — same energy-drink base, real orange juice, no syrup.

FAQ

Is there any alcohol in this?

None. Both the syrup and the juice are alcohol-free, and the energy drink obviously carries none either — this is a fully non-alcoholic mocktail-style drink, matching what the syrup itself is built to be.

Is “Blue Lagoon” a trademarked drink name?

No — it’s a generic, decades-old mocktail/cocktail name in wide public use, not a name owned by any single coffee chain, restaurant, or brand. We picked it because it’s the accurate, recognizable name for this exact flavor combination (blue curaçao, citrus, and a fizzy base), the same way “Moscow Mule” or “Shirley Temple” describe a drink without belonging to anyone.

Where does the blue color come from?

Entirely from our homemade Blue Curaçao Syrup — see that recipe for the full method. It’s food coloring in a sugar-and-orange-extract syrup, not a special dye added at this stage.
