Dunkin' Donuts delicious coffee beverages are 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.

I recently dove to the bottom of the donut hole to discover whether Dunkin' offer free beverage refills. Let's check it out!

  • Dunkin's refill policy varies between locations, but they generally take a similar approach
  • Bringing a reusable mug often costs the same as a small coffee or other refill price no matter the size
  • What drinks qualify for this vary between locations, but most often non-blended teas and coffees apply
  • I recommend checking with your local store's policy rules with barista before handing your mug over

Does Dunkin Donuts Offer Free Refills? 

Technically, Dunkin' Donuts does not offer free refills, but many locations offer a discount on refills in reusable mugs.

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, 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.

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.

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.

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 person 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.
