Hardtank’s cold brew machine uses a patented rapid cold brew extraction method that transforms how businesses brew cold coffee. Instead of waiting 12–24 hours like traditional systems, Hardtank’s dynamic recirculation technology actively circulates water through the coffee grounds, achieving complete extraction in under one hour. This process maximises the interaction between water and coffee, boosting both flavour and efficiency without sacrificing quality.
The device is built from high-grade, food-safe stainless steel, ensuring durability and a clean brewing environment for years of reliable use. Hardtank’s double filtration system delivers a clear, smooth cold brew free from bitterness or astringency, while the closed brewing chamber minimises oxidation and extends shelf life. Hardtank automates cleaning, dispensing, and recipe control, making it easy to scale up production and maintain the highest hygiene standards with minimal labour.
