Dunkin's Secret: What Does Dunkin' Use for Liquid Sugar?

4 min read

According to Dunkin's allergen and ingredient guide, the chain's liquid cane sugar contains just three key ingredients: sugar, water, and a preservative. This simple concoction is the key to the smooth, seamless sweetness found in many of Dunkin's signature iced beverages.

Quick Summary

Dunkin's liquid sugar is a straightforward simple syrup made from sugar, water, and potassium sorbate, used to perfectly sweeten iced and frozen drinks. It is distinct from the cream-based flavor swirls and can be compared to homemade simple syrup.

Key Points

  • Core Ingredients: Dunkin's liquid sugar is officially 'Liquid Cane Sugar' and consists of sugar, water, and potassium sorbate.

  • Not a Flavor Swirl: Unlike the creamy and flavored swirls (e.g., caramel), liquid cane sugar provides pure, neutral sweetness.

  • Designed for Iced Drinks: The syrup dissolves instantly in cold beverages, preventing the gritty texture caused by granulated sugar.

  • Operational Efficiency: Using liquid sugar allows baristas to sweeten iced drinks quickly and consistently, improving service speed.

  • Vegan Status: The liquid cane sugar is dairy-free, but its vegan status depends on the cane sugar refining process (some use bone char).

  • DIY Alternative: A simple and preservative-free version can be made at home by dissolving equal parts sugar and water over heat.

  • High Fructose Corn Syrup: While not in the standard liquid sugar, high fructose corn syrup is used in some of Dunkin's other sweetened products, such as certain flavor swirls.

Unpacking the Ingredients in Dunkin's Liquid Sugar

Many coffee lovers are curious about the ingredients behind their favorite beverage customizations. The simple, non-flavored liquid sweetener at Dunkin' is officially called "Liquid Cane Sugar". Its composition is refreshingly simple when compared to some of the more complex flavor swirls offered by the chain. The Dunkin' website's official allergen and ingredient guide lists its liquid cane sugar as containing just three components: sugar, water, and potassium sorbate.

  • Sugar: The primary ingredient, which provides the sweetness.
  • Water: Used to dissolve the sugar, creating the liquid consistency.
  • Potassium Sorbate: A food-grade preservative used to extend the shelf life of the syrup and prevent microbial growth.

This simple formula is effectively a form of simple syrup, a common sweetener in the coffee and cocktail world. It is important to note that this is different from Dunkin's other sweetener options, such as the flavor swirls and sugar packets, each of which has a different composition and use.

The Difference Between Dunkin's Liquid Sugar and Flavor Swirls

Customers at Dunkin' often confuse liquid sugar with the more decadent flavor swirls. The key difference is that liquid cane sugar provides only a neutral sweetness, while flavor swirls are designed to add both sweetness and a specific flavor, such as caramel or mocha.

  • Liquid Sugar: Unsweetened and unflavored. Vegan-friendly (subject to sugar processing, see FAQs). Adds minimal calories. Can be used in any drink.
  • Flavor Swirls: Sweet, creamy, and flavorful. With the exception of the mocha swirl, most contain dairy. Add significantly more calories due to their creamy base.

By requesting "liquid sugar," a customer can control the level of sweetness without introducing additional creamy flavors. This is particularly important for those who prefer the pure taste of coffee with a simple sweetening.

Why Dunkin' Opts for Liquid Sugar in Many Iced Drinks

There are several operational and quality-based reasons why Dunkin' uses a liquid sweetener for its iced and frozen beverages. It all comes down to consistency and efficiency. Granulated sugar does not dissolve easily in cold liquids, often leaving behind a gritty texture at the bottom of the cup. Liquid sugar, on the other hand, mixes instantly and evenly, ensuring that every sip is consistently sweet.

For baristas, this is a major time-saver, particularly during peak hours. Pouring a pre-made syrup is much faster than stirring granulated sugar into a cold drink until it dissolves. This operational efficiency helps maintain quick service times, a key part of the Dunkin' experience. The use of a standard liquid syrup also ensures consistent flavor across all locations, as the sweetness level is precisely measured.

Can You Request Granulated Sugar for Iced Drinks?

While liquid sugar is the standard for iced beverages at many locations, some customers prefer the taste of granulated sugar. As noted in discussions on platforms like Reddit, customers can often request "melted sugar" which is made by dissolving granulated sugar in a small amount of hot water. This extra step may not be standard practice at all stores, and the experience can vary depending on the specific location and the training of the staff. If you're a fan of granulated sugar's taste, it's worth asking, but be aware it might not be the quickest or most reliable option.

Making Your Own Dunkin'-Style Simple Syrup

Recreating Dunkin's simple syrup at home is a straightforward process, eliminating preservatives and allowing for full control over the sweetness. A classic simple syrup uses a 1:1 ratio of sugar to water.

Ingredients:

  • 1 cup white granulated sugar
  • 1 cup water

Instructions:

  1. Combine the water and sugar in a small saucepan.
  2. Heat over medium heat, stirring constantly until the sugar is completely dissolved. Do not bring to a boil.
  3. Remove from heat and allow the syrup to cool completely.
  4. Store the simple syrup in an airtight container in the refrigerator for up to several weeks.

This homemade version is perfect for mixing into iced coffee, iced tea, or cocktails, providing the same smooth sweetness without the added preservatives. For a richer flavor, you can try a 2:1 ratio (2 parts sugar to 1 part water) to create a thick simple syrup.
