Benefits of Coffee Soda

When I first stumbled across the concept of coffee soda, I was sceptical. Yet, as I delved into making my own, I discovered several surprisingly delightful benefits that transformed my scepticism into enthusiasm. Here's why coffee soda might just become your new favourite caffeine kick.

Refreshing Twist on Traditional Coffee: The first thing I noticed was how refreshing it felt compared to my usual hot coffee. On warm days, the chilled fizziness adds a revitalising twist, making it a fantastic summer beverage.

Customisable Caffeine Content: Depending on how strong I brew my coffee or the amount I choose to use, I can adjust the caffeine content to suit my needs. This flexibility is perfect for those days when I need an extra boost or prefer to go light on caffeine.

Easy and Quick to Make: Unlike some coffee drinks that require special equipment or a barista's skill, coffee soda is remarkably simple to make. With just a few ingredients, it's ready in minutes. The ease of crafting this drink has saved me countless trips to the coffee shop, not to mention a fair amount of money.

Healthier Alternative: For those watching their sugar intake, coffee soda can be a healthier alternative to sugary soft drinks or flavoured coffees. I prefer to control the sweetness by adding just a hint of natural sweetener, making it a guilt-free pleasure.

Boosts Metabolism: Like regular coffee, coffee soda can give your metabolism a slight boost. The combination of caffeine and cold can enhance this effect, making it a fitting companion for my morning routine.

Embracing coffee soda has opened up a new avenue in my caffeine consumption, offering a unique blend of perks. It's become a favourite in my beverage repertoire, particularly during the warmer months. Now, let's dive into how you can make your own coffee soda with ease.

Tips for the Perfect Brew

When it comes to creating the perfect coffee soda, there are a few tricks I've picked up that make all the difference. It's not just about putting coffee and soda water together; it's about how you blend and balance the flavours to suit your taste.

Select Quality Ingredients: The foundation of an exceptional coffee soda lies in the quality of the coffee and sparkling water you use. Opt for a cold brew concentrate for a smoother, richer flavour. For the sparkling water, choose one that's crisp and not too mineral-heavy, as this can affect the overall taste.

Cold Brew Concentration Matters: The strength of your cold brew can significantly impact the taste of your coffee soda. If it's too weak, the sparkling water will dilute it further, making it bland. A robust cold brew ensures that when mixed, you still get that profound coffee essence.

Sweeten Smartly: The type of sweetener and how much you use can dramatically change the drink's profile. Simple syrup is your best bet as it mixes seamlessly with the cold liquid. Begin with a small amount, tasting as you go, to avoid oversweetening.

Chill Everything: Ensure your cold brew and sparkling water are chilled to the same temperature. This keeps the coffee soda refreshing and prevents the ice (if you choose to use it) from melting too quickly, which can water down your drink.

Customisation Is Key: The beauty of coffee soda is its versatility. Feel free to tweak the basic recipe to your liking.

Enjoy Your Custom Coffee Soda!

After experimenting with various ingredients and fine-tuning your mix to perfection, you're ready to enjoy your custom coffee soda. It's a refreshing twist to your daily caffeine fix, combining the richness of coffee with the crispness of soda. Here's how I like to make mine, and trust me, it's simpler than you might think.


  1. Chill Your Ingredients: Make sure your cold brew concentrate and sparkling water are thoroughly chilled. This step is crucial for that refreshing touch.
  2. Prepare Your Glass: Fill a glass halfway with ice cubes to keep your drink cool.
  3. Mix: Pour equal parts of cold brew concentrate and sparkling water into the glass. I usually stick with a 1:1 ratio, but feel free to adjust according to your personal preference.
  4. Sweeten: Add simple syrup to taste. Start with a small amount and increase as needed.
  5. Customise: This step is where you can get creative. Add a splash of cream or milk for a smoother taste, or drop in a slice of citrus for a zesty kick.
  6. Stir Gently: Mix your drink with a stirrer or a spoon, but do it gently to avoid losing the fizz.

And there you have it - your very own custom coffee soda! This drink is all about personalisation. Don't be afraid to adjust the ratios or add-ins to match your taste. Whether it's a hot summer day or you're just looking for something different, a glass of coffee soda can be the perfect pick-me-up.
