Flatiron Coffee was established in 2009 in Boulder, Colorado. Since then, we’ve focused on crafting gourmet specialty coffee with an emphasis on quality. Almost all of our products are local and we always strive to create interesting specialties that can’t be found anywhere else. (Like our Ice Cap! It’s our signature drink, featuring our delicious cold brewed espresso sweetened with vanilla, locally sourced whole milk, and then the whole she-bang is churned in an ice-cream machine for one of the best drinks around town.) Not only that, but our baristas are specifically bar-trained on our La Marzzocco to pull shots, steam milk, and concoct delicious espresso beverages—we do everything by hand here! No machines to tamp for us or steam our milk or pull our shots. We think the best coffee drinks come from people, not machines.

We have an extensive collection of food and pastries catering to dietary restrictions and offer many gluten-free and vegan options.

We support many other local businesses and organizations: Flatiron Coffee has donated to the Colorado Shakespeare Festival, the Boulder Chamber Orchestra, the Boulder Valley School District, Colorado Public Radio, Rocky Mountain Cancer Assistance, the Boulder Homeless Shelter and many more. We believe that a strong community creates a place where everyone is welcome and everyone can lay the groundwork for a better future.

Flatiron Coffee also strives to be as environmentally friendly as possible with a goal to become as close to zero-waste as we can. Our store has all-compostable cups, lids, straws, and plasticware.

The owner, Melissa, is a Colorado local and graduated from the University of Colorado at Boulder. She has been hand-crafting specialty espresso drinks for more than two decades and is always looking for new and innovative ways to prepare coffee without ever becoming too pretentious.
