India's First Brand To Use Air Classifying Mills (ACMs) Spices begin to lose their pungency and flavour at around 60° C.But most spice companies use old grinding machines like hammer mills that reach high temperatures of up to 120° C. We are the first in India to use Air Classifying Mills (ACMs) to grind all our spices. ACMs work at only 30° – 40° C, so our spices can retain their full flavour and smell till you start to cook.
