The Original Brewing Flask was created by inventor Patrick Heiberg
The original coffee Brewing Flask from Boilbrew is handmade from high quality Borosilicate 3.3 glass, for maximum strength, optical clarity, corrosion resistance, and durability. The Brewing Flask comes with a custom made silicone grip for improved heat resistance and a non-slippery surface, giving the brewer full control of the handling of the Brewing Flask.
