Does Dunkin Do Refills For Free? (Find Out How To Get Yours)

Dunkin Donuts is my go-to when I'm feeling a little groggy in the morning. Their delicious coffee beverages give me the kickstart I need to start my day.

They're so good that I wish I had a bottomless cup to keep me fueled all day. So that's how I got to wondering, do they offer free refills on their drinks?

The answer to that question is...kind of.

The short answer is that Dunkin doesn't technically offer free beverage refills. However, you can buy a Dunkin’ Donuts travel mug and refill it with your favorite beverage for a small discount.

In my experience, the refill cup policy at Dunkin' Donuts can vary depending on the location.[1] However, I've found that many Dunkin' locations tend to follow a similar approach.

If you bring your own reusable mug or buy one of their refillable cups or mugs, they are generally willing to fill it with hot coffee and charge you for the price of a small coffee or a refill, even if your mug is a medium size or larger.

You can bring your own ceramic travel coffee mug, which I love, or you can opt for a Dunkin Donuts travel mug.

The largest tumbler size available in their store is 24 ounces, so any size up to that should be perfectly fine to use. Just be careful of the caffeine content adding up!

The policy can vary more significantly from store to store for drinks other than hot coffee. For example, many locations will not make a latte or other blended drinks in your mug.

This is mainly because they need to measure the ingredients, and using an unfamiliar cup could make that challenging.

However, with non-blended drinks like Dunkin iced coffee, cold brew, tea, and hot chocolate, they usually have no problem filling my reusable travel mug.

Of course, it's worth noting that this can vary depending on the store you visit, so always check with the store before you hand them your Dunkin Donuts mug.

What Drinks Qualify For Refills At Dunkin Donuts?

The policy for refills generally applies to non-blended drinks like hot or iced coffee, cold brew, tea, espresso, and hot chocolate.

I'm an iced coffee guy in the summer, and the employees at my local Dunkin know my mug by heart. I get my favorite coffee with a blueberry Dunkin flavor shot (which they also have memorized).

Tea lovers are included, too. Dunkin' offers a variety of iced teas, including unsweetened black tea, green tea, and flavored teas you can have filled into your travel mug.

And let's not forget about the classic comfort of hot chocolate. It’s my go-to choice if I'm looking for a warm treat on a chilly day or a cozy beverage to uplift my spirits.

It's important to note that while these non-blended drinks are typically eligible for refills, it's always a good idea to check with the specific Dunkin' Donuts location you visit, as policies can vary slightly.

Will Dunkin Fill Reusable Cups If You Bring Your Own?

Again, the policy regarding refilling reusable cups will vary. What one location offers could be completely different from the next.

However, many Dunkin' Donuts locations are accommodating when refilling your own cup or reusable tumbler.

Refilling your mug aligns with the company's commitment to sustainability, reducing waste, and supporting the environment, which is also important to me.

It's a way for Dunkin' Donuts and its customers to minimize the use of disposable materials. It can also save money all around.

While some locations may have specific guidelines or restrictions like limitations on mug sizes or certain drink categories, many Dunkin' Donuts stores are happy to refill your own mug as long as it meets their criteria.
