Background & Serving Details
Fountain drinks have been a staple of American fast-casual dining for decades, and Smashburger maintains that tradition with its partnership with The Coca-Cola Company. Guests can choose from classics like Coca-Cola®, Diet Coke®, Sprite®, Dr Pepper®, Barq’s Root Beer®, Minute Maid® Lemonade, and Coke Zero Sugar®.
The 20-ounce cup is perfectly sized for a standard meal, keeping its fizz and chill through the entire dining experience. Each cup is filled to order with ice and freshly carbonated soda from the fountain machine — never pre-bottled.

Each fountain drink varies slightly depending on your choice, but the base ingredients include:
- Carbonated water

- Caramel color (for cola flavors)
- Phosphoric acid

Taste & Texture Review
The 20 OZ Fountain Drink offers a burst of cold carbonation that cuts through the richness of Smashburger’s burgers and sides. Each sip delivers a fizzy refreshment that resets your palate between bites. For cola lovers, the sweet-acidic balance pairs beautifully with smoky burgers like the Double Colorado Smash or BBQ Bacon Smash.
Citrus-based drinks like Sprite® work especially well with spicy meals like the Spicy Jalapeño Smash, providing a bright contrast to its heat. Every flavor offers a different experience, but the signature effervescence and crisp finish remain consistent.
Chef’s Notes & Serving Insight
Although it may seem simple, Smashburger’s approach to fountain service follows precision. Machines are calibrated for exact syrup-to-carbonation ratios to maintain taste quality. Ice levels are standardized so the drink stays cold without dilution.
Each fountain line is cleaned daily to preserve the integrity of flavors and avoid cross-mixing between sodas. That’s why the Coca-Cola pour at Smashburger tastes as fresh as from a dedicated beverage bar.
Flavor Harmony & Pairings
Different fountain options pair with different burgers and sides:

Nutritional Perspective
A 20 OZ regular Coca-Cola contains about 65 grams of sugar, roughly equal to 16 teaspoons. While it’s best enjoyed in moderation, pairing it with protein-heavy meals like the Double Classic Smash can slow sugar absorption.
For those watching calories or sugar intake, the Diet Coke and Coke Zero options offer the same carbonated satisfaction without the calories. Hydration-minded guests can also choose iced tea or Craft Refreshers as alternatives.
Smashburger’s Beverage Philosophy
Smashburger believes every meal deserves balance — a fresh, customizable drink that complements handcrafted food. By partnering with Coca-Cola, they ensure consistent flavor and quality nationwide.
The 20 OZ Fountain Drink symbolizes that philosophy: flexible choices, premium dispensing systems, and refreshment that matches the brand’s focus on craft and freshness.
Final Thoughts
The 20 OZ Fountain Drink is the unsung hero of the Smashburger menu — simple yet essential. Its perfect portion size, customizable flavor options, and fresh carbonation make it the ideal companion for any meal.
Whether you grab a Coke Classic with a burger combo or a lemonade on a hot day, this drink turns an ordinary meal into a complete Smashburger experience. Pure refreshment in every sip — that’s what keeps fans coming back.
