In the world of specialty coffee, we’re always looking for tools that enhance the way we experience each cup. From grinders to brewers, every piece of equipment plays a role in shaping the final flavor. But what about glassware? Can a carafe or a cup truly make a difference in taste?
That was the question on my mind when I first encountered ICOSA’s Cyclone Carafe and Alto Glass—two products that have quickly become some of the most sought-after coffee accessories of the year.
A First Look at ICOSA
My introduction to ICOSA started in South Korea when my friend Jay Kim - UFO gifted me the Alto glass. We talked about how its unique design could enhance the coffee-drinking experience. Then, during a trip to Thailand, I had another encounter—this time with the Cyclone Carafe, handed to me by Chai - Yellow Stuff.
Both times, I was intrigued but skeptical. ICOSA products were constantly sold out, making them hard to get, and I wanted to understand why. Could a piece of glassware really transform the way we taste coffee?
The Alto Glass: A Lesson in Swirling
I’ll admit, my first experience with the Alto glass wasn’t mind-blowing. I poured my coffee in, swirled it a few times, and… nothing. No noticeable difference in taste. I felt a little disappointed.
But Jay kept insisting: “This is the best coffee glass I’ve ever used. You just have to use it right.”
That’s when I realized my mistake—I wasn’t swirling enough.
Here’s the trick:
- Swirl the coffee at least 20 times—and do it fast.
- Use a small amount of coffee in the glass.
The result? A completely different experience. The coffee became sweeter, the acidity more delicate, and the body rounder and creamier. It was a game-changer. Unlike traditional glassware, which lets coffee sit still, the Alto’s aerodynamic shape encourages movement, unlocking flavors that would otherwise remain hidden.
The Cyclone Carafe: A Brewer’s Secret Weapon
As a competitive brewer, I’m always searching for ways to enhance coffee presentation and flavor. That’s why, when preparing for the 2025 U.S. Brewers Cup, I chose to use the Cyclone Carafe during my open service.
What makes it special? The wave-like aeration design, similar to the Alto glass, naturally aerates the coffee as you pour. This enhances the aromatic experience and brings out brighter acidity and greater complexity—all essential for high-level coffee competitions.
I’ve always encouraged aerating coffee, much like how wine is aerated to unlock deeper flavors. With the Cyclone Carafe, this process becomes effortless. It helped me achieve a 3rd place finish in the 2025 U.S. Brewers Cup, proving that the right tools can make a real impact.
Final Thoughts: Is It Worth It?
For anyone serious about improving their coffee experience, ICOSA’s Cyclone Carafe and Alto Glass are worth exploring. They take some time to master, but once you do, the results are undeniable.
Try it yourself—taste your coffee before and after swirling. You might be surprised at the difference.
Happy brewing!
