Great tasting coffee depends on precise temperature and correct contact time of the brew water with the ground coffee. The Breville Precision Brewer uses innovative technologies to achieve exactly this. The temperature is precisely controlled during the brewing cycle by means of Proportional Integral Derivative (PID) technology. A patented “Steep & Release” system ensures the contact time between water and coffee is optimal, regardless of the brew volume, in order to maximise flavour potential.
