For years, Seattle-based Alaska Airlines has been brewing and pouring Seattle-based Starbucks coffee on Alaska and Horizon Airlines flights.

But on or around December 1, 2023, the in-flight coffee will switch over to a custom roast from Portland-based Stumptown Coffee that’s a spinoff of Stumptown’s best-selling Holler Mountain.

Alaska says its custom Stumptown blend was specially crafted to be enjoyed at 30,000 feet, where tastebuds react differently. And that it was approved only after months of development and in-flight testing.

That’s how serious Alaska Airlines – and travelers – are about coffee.

“Alaska’s medium-dark blend uses the same clean and sweet base as Holler Mountain, but with a primary focus on a roast that mellows acidity and introduces just enough toastiness to please a wide range of palates,” the airline said in a statement. “It’s exceptionally smooth and balanced, with aromatic notes of toasted marshmallows, browned butter, and toffee with delicate hints of citrus and cherry. Additionally, Stumptown dialed in this roast to be delicious when served black or with the addition of creamer or oat milk” which is also offered on Alaska flights.

We’ll reserve judgment until we taste the coffee for ourselves. With and without those tiny Biscoff cookies.
