The California Cooler is a refreshing, zesty cocktail that’s like a cool ocean breeze in a glass—perfect for those warm, sunny days. With its bright citrus, cooling mint, and just the right touch of sweetness, it’s a go-to for summer evenings or any time you want to bring a little California sunshine to your day. I’ve made this drink more times than I can count, and it’s always a crowd-pleaser. Let me walk you through how to make it, along with tips, tweaks, and food pairings to make it your own.
California Cooler
Ingredients
You’ll need:
- 2 oz (60 ml) white rum
- 1 oz (30 ml) fresh lime juice
- 8–10 fresh mint leaves
- 0.5 oz (15 ml) simple syrup (or adjust to taste)
- Soda water (enough to top off your glass)
- Ice (to fill your glass)
Optional garnish:
- A sprig of mint and a lime wedge for that perfect finishing touch.
Glassware tip: A highball glass works best to keep the drink chilled and let all the flavors shine, but a Collins glass will work just as well.
Method
- In a shaker, muddle the mint leaves with the simple syrup. This step releases the mint’s natural oils, giving your drink that fresh, cooling flavor. (Don’t skip this—it’s key!)
- Add the white rum, fresh lime juice, and a handful of ice to the shaker. Shake well until it’s nicely chilled—about 10–15 seconds.
- Fill your highball glass with ice, then strain the mixture into the glass.
- Top it off with soda water. Give it a gentle stir to combine everything.
- Garnish with a sprig of mint and a lime wedge, and you’re ready to sip and relax!
Make-Ahead Notes
If you’re hosting, you can mix the rum, lime juice, and simple syrup in advance and keep it chilled. Just wait to add the soda water and garnish until you’re ready to serve, so the fizz stays fresh.
Tips & Tricks
- Fresh is best: Use fresh lime juice and mint for the brightest flavors. Bottled lime juice just doesn’t compare.
- Adjust sweetness: If you like your cocktails less sweet, start with 0.25 oz (7 ml) of simple syrup and add more if needed.
- Substitutions: No simple syrup? Use honey or agave syrup instead. Want a healthier option? Reduce the sweetener or skip it altogether.
- Low-calorie version: Use flavored sparkling water instead of soda water and a low-calorie sweetener.
Food Pairings
Pairing the California Cooler with the right bites can take your experience to the next level. Here are some ideas:
- Grilled Shrimp: The citrusy drink balances the smoky, savory flavors of shrimp perfectly.
- Fresh Fruit Salad: The light, zesty cocktail highlights the sweetness of ripe summer fruits.
- Spicy Tacos: The minty coolness is a great counterbalance to spicy, bold flavors.
I’ve served this drink with grilled shrimp tacos at summer barbecues, and trust me—it’s a match made in heaven.
Variations to Try
Once you’ve mastered the classic, shake things up with these fun twists:

Storage Tips
This cocktail is best enjoyed fresh, but if you need to prep ahead, mix the rum, lime juice, and simple syrup and refrigerate for up to 24 hours. Keep the mint separate to avoid it turning bitter, and add soda water and garnish just before serving.
