Abstract
A coffee brewing system and method brew hot coffee at an elevated temperature by mixing coffee grounds with hot water, filtering the hot coffee to remove at least some of the coffee grounds from the hot coffee to form filtered hot coffee, and rapidly cooling the filtered hot coffee to reduce a temperature of the filtered hot coffee to form cooled coffee. The coffee optionally may be mixed with a gas, such as nitrogen, prior to serving the cooled coffee. The system and method can rapidly produce cold coffee in large amounts without diluting the coffee in water or ice, or waiting for the coffee to cool in a refrigerated environment.

A method comprising:
- brewing hot coffee at an elevated temperature by mixing coffee grounds with hot water in a brewing tank;
- filtering the hot coffee to remove at least some of the coffee grounds from the hot coffee to form filtered hot coffee;
- and
- rapidly cooling the filtered hot coffee with a plate heat exchanger having separate channels in which one or more of water or glycol is pumped to cool at least seventy-five gallons of the filtered hot coffee without diluting the filtered hot coffee to reduce a temperature of the filtered hot coffee by at least one hundred forty degrees within five minutes to form cooled coffee.
