This hand-blown borosilicate glass brewer features exceptional thermal resilience, tolerating instantaneous temperature shifts from −30°C to +150°C without cracking and enduring peak temperatures up to 600°C. The adjustable drip mechanism allows you to customize brew strength to your preference, while the removable water tank makes the cold brew process effortless and refilling seamless. Cold brewing naturally produces coffee with significantly lower acidity, a distinctly sweeter and richer flavor profile d to traditional hot brewing methods.
