[0001] Priority claim

[0002] This application claims priority under 35 U.S.C. 119(e) to U.S. Provisional Patent Application No. 62 / 857,246, filed on June 4, 2019, entitled “System and Method For Cupping Cold Brew Coffee,” the entire text of which is incorporated herein by reference. Technical Field

[0003] The present disclosure relates to systems and methods for brewing coffee. Background Art

[0004] At present, cold coffee brewing, also known as cold brewing, immersion brewing, cold water extraction or cold pressing, is the process of soaking coffee grounds in cold water or water at ambient temperature / room temperature for a long time. The ground coffee beans are soaked in water for a long time. After soaking, the coffee grounds are filtered out of water after they have been soaked, for example, using a paper filter, a fine metal sieve, a French press or a felt in the case of a brewing system. The result is a coffee concentrate, which is diluted with water or milk before drinking, and is drunk while hot, on the ice or mixed with ice cubes and other ingredients such as chocolate, for example. Unfortunately, the known technology for cold brewing coffee is usually not converted into different scales. The coffee brewed in a small batch brewing machine tastes different from the coffee brewed in a larger batch brewing machine because the design of the brewing machine causes different extractions.

[0005] Coffee cupping is a technique used to analyze the sensory properties of hot brewed coffee. It is a professional practice performed by coffee buyers, judges, enthusiasts, and professionals. Producers and buyers around the world often use coffee cupping to check the quality or flavor profile of a particular batch of coffee. In cupping, coffee is scored in terms of, for example, aroma, fragrance, flavor, acidity, body, mouthfeel, uniformity, balance, cleanliness, sweetness, and aftertaste. Cupping is also used to identify defects in coffee and evaluate coffee blends. In addition, cupping is also a method for determining preferences between different coffees and brewing parameters.

[0006] The standard coffee cupping procedure usually involves taking a deep sniff of the coffee, followed by a quick sip so it spreads over the back of the tongue and across the taste buds. Coffee tasters attempt to assess aspects of the coffee's taste, body (texture or mouthfeel, such as oiliness), sweetness, acidity (a strong, rich sensation, like biting into an orange), flavor, and aftertaste.

[0007] Because the ground coffee beans in cold brew coffee never come into contact with hot water, the process of extracting flavor from the beans produces a different chemical profile than conventional brewing methods. Coffee beans contain several components that are more soluble at higher temperatures, such as caffeine, oils, and fatty acids. When brewed in equal amounts, brewing at lower temperatures results in lower acidity and lower caffeine content. Its acidity per serving is about 65% to 70% lower than hot drip coffee or espresso. Unfortunately, while the coffee cupping associated with hot brew coffee is well known, there is currently no equivalent procedure or supporting products for cold brew coffee.

[0008] Therefore, there is a need for an immersion coffee brewing system that can solve these problems. Summary of the invention

[0009] An immersion coffee or tea brewing (ICB) system is disclosed. The ICB system includes a brewing container having a top and a filter basket. The brewing container is configured to receive a closeable filter having coffee or tea and water in the brewing container. The filter basket is configured to removably attach to the top of the brewing container, hold the closeable filter, and drain liquid in the closeable filter into the brewing container.

[0010] The ICB system may also include a lid configured to be removably attached to the top of the brewing container before the filter basket is removably attached, and to seal the brewing container to prevent degassing of the coffee or tea when immersed in the water. The lid may include a degassing opening and may be configured to rotate along the top of the brewing container from a sealed position that prevents degassing to an open position that allows degassing through the degassing opening. The brewing container may include a spout at the top of the brewing container, wherein the spout is configured to allow degassing when the lid is rotated to the open position and the degassing opening of the lid is positioned adjacent to the spout of the brewing container.

[0011] The ICB system may also include the closable filter, wherein the closable filter is a filter bag having an open top configured to receive the coffee or tea and the water. The closable filter may further be configured to be partially sealed by twisting the open top to a closed position after receiving the coffee or tea and the water.
