The interior contour is specifically shaped to encourage a smooth, consistent flow as you pour. This helps maintain the crema on an espresso shot and ensures the liquid aerates properly as it hits the glass, which can subtly improve the mouthfeel and aroma of your drink.

Yes. It is crafted from laboratory-grade borosilicate glass, which is specifically engineered to withstand rapid temperature changes without cracking. It is perfectly safe for hot espresso shots.

While each piece is handmade, NotNeutral maintains strict quality control standards to ensure consistency across the Ciclone line. You may notice very slight, subtle variations that are characteristic of artisanal glasswork, but the capacity and overall profile remain uniform.

Yes, the borosilicate glass is durable enough for dishwasher use. However, because it is a delicate, handmade vessel, we recommend placing it on the top rack or hand-washing to prevent it from knocking against other dishes.

The Ciclone is significantly lighter than ceramic, which gives it a more delicate, refined feel in the hand. The ergonomic profile is designed to nestle comfortably in your fingers, though it lacks the heft of a traditional thick-walled mug.
