Cold brew coffee, also called cold water extraction or cold pressing, is the process of steeping coffee grounds in water at cool temperatures for an extended period. Coarse-ground beans are soaked in water for about 12 to 24 hours. [1] [2]
The water is normally kept at room temperature, but chilled water can be used. After the grounds have been steeped, they are filtered out of the water using a paper coffee filter, or a fine metal sieve (e.g. in a French press), or felt. The result is a coffee concentrate that is diluted with water or milk, and is sometimes served hot, but often served chilled, over ice, or blended with ice and other ingredients such as chocolate. [3]
Cold brew coffee originated in Japan, where it has been a traditional method of coffee brewing for centuries. [4] Slow-drip cold brew, also known as Kyoto-style, [5] or as Dutch coffee in East Asia (after the name of coffee essences brought to Asia by the Dutch), [6] refers to a process in which water is dripped through coffee grounds at room temperature over the course of many hours. [7]
Because the ground coffee beans in cold-brewed coffee never come into contact with heated water, the process of leaching flavor from the beans produces a chemical profile different from conventional brewing methods. [8] [9] Coffee beans contain a number of parts that are more soluble at higher temperatures, such as caffeine, oils and fatty acids. However, brewing at a lower temperature for 24 hours results in higher caffeine content when brewed in equal volume compared to 6 minutes at 98 °C (208 °F). [10] The pH of cold and hot brew coffee is similar but cold brew coffee has a lower titratable acid concentration. [11] Both pH and titratable acidity influence taste. [12]
Nitro cold brew is a variation of cold brew coffee that uses the addition of nitrogen gas to create a smooth texture, delivering the nitrogenated coffee from a nitrogen beer tap system. [13] It was introduced in the early 2010s. [14]
Production of nitro cold brew coffee begins with the making of cold brew coffee. [15] Once the grounds are adequately steeped, the coffee is poured into a room-temperature bottle or keg. [16] As the cold brew is poured into a cup, it is charged with nitrogen to give it a rich, creamy head of foam, similar to draft beer. (Though most beers and soft drinks are charged with carbon dioxide, nitrogen is occasionally used in darker stouts, resulting in a smoother finish.) Nitro cold brew is typically served chilled but without ice, which would damage the foamy top. [16]
Nitro cold brew was first offered at third wave coffee shops in the early 2010s, but the exact origin is disputed. The process is said by Men's Journal to have originated in 2013 at craft coffee houses Cuvee Coffee in Austin, Texas, and Stumptown in Portland, Oregon. [17] However, Esquire gives credit to the draft coffee at The Queens Kickshaw in New York in 2011 as a predecessor. [18] Cuvee Coffee first offered nitro cold brew, on tap, at the Slow Food Quiz Bowl in Austin, Texas, on August 14, 2012.[ citation needed ] [19] The Ball Corporation issued a press release citing Cuvee as the first company to can cold brew in their widget cans, and BevNet awarded Cuvee the Best Packaging Innovation, calling them "the first cold brew brand to market a nitrogenated offering." [20] Stumptown and Cuvee began offering canned beverages with a nitrogen-filled capsule to pressurize the can by 2015. [21] [22] Starbucks introduced the beverage at 500 stores in the summer of 2016, [23] [24] preceded in the Los Angeles market by The Coffee Bean & Tea Leaf. [25] By 2020, Starbucks offered the beverage at more than half of its locations across the United States, making it a staple menu item. [26] Nitro cold brew is available from wholesalers in some markets in kegs. RISE Brewing Co. says it can fill up to 1,500 kegs a day of nitro cold brew coffee. [27]
A drink or beverage is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, juice, smoothies and soft drinks. Traditionally warm beverages include coffee, tea, and hot chocolate. Caffeinated drinks that contain the stimulant caffeine have a long history.
Draught beer, also spelt draft, is beer served from a cask or keg rather than from a bottle or can. Draught beer served from a pressurised keg is also known as keg beer.
Espresso is a concentrated form of coffee produced by forcing hot water under high pressure through finely-ground coffee beans. Originating in Italy, espresso has become one of the most popular coffee-brewing methods worldwide. It is characterized by its small serving size, typically 25–30 ml, and its distinctive layers: a dark body topped with a lighter-colored foam called crema.
Instant coffee is a beverage derived from brewed coffee beans that enables people to quickly prepare hot coffee by adding hot water or milk to coffee solids in powdered or crystallized form and stirring. The product was first invented in Invercargill, the largest city in Southland, New Zealand, in 1890. Instant coffee solids refers to the dehydrated and packaged solids available at retail used to make instant coffee. Instant coffee solids are commercially prepared by either freeze-drying or spray drying, after which it can be rehydrated. Instant coffee in a concentrated liquid form, as a beverage, is also manufactured.
Drip coffee is made by pouring hot water onto ground coffee beans, allowing it to brew while seeping through. There are several methods for doing this, including using a filter. Terms used for the resulting coffee often reflect the method used, such as drip-brewed coffee, or, somewhat inaccurately, filtered coffee in general. Manually brewed drip coffee is typically referred to as pour-over coffee. Water seeps through the ground coffee, absorbing its constituent chemical compounds, and then passes through a filter. The used coffee grounds are retained in the filter, while the brewed coffee is collected in a vessel such as a carafe or pot.
Coffee is a beverage brewed from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It has the highest sales in the world market for hot drinks.
A caffeinated drink, or caffeinated beverage, is a drink that contains caffeine, a stimulant that is legal practically all over the world. Some are naturally caffeinated while others have caffeine added as an ingredient.
A keg is a small cask used for storing liquids. Wooden kegs made by a cooper were used to transport nails, gunpowder, and a variety of liquids. Nowadays a keg is normally constructed of stainless steel, although aluminium can be used if it is coated with plastic on the inside. It is commonly used to store, transport, and serve beer. Other alcoholic or non-alcoholic drinks, carbonated or non-carbonated, may be housed in a keg as well. Carbonated drinks are generally kept under pressure in order to maintain carbon dioxide in solution, preventing the beverage from becoming flat.
Peet's Coffee is a San Francisco Bay Area-based specialty coffee roaster and retailer owned by JAB Holding Company via JDE Peet's. Founded in 1966 by Alfred Peet in Berkeley, California, Peet's introduced the United States to its darker roasted Arabica coffee in blends including French roast and grades appropriate for espresso drinks. Peet's offers freshly roasted beans, brewed coffee and espresso beverages, as well as bottled cold brew. In 2007, Peet's opened the first LEED Gold Certified roastery in the United States. Peet's coffee is sold in over 14,000 grocery stores across the United States.
A coffee bean is a seed from the Coffea plant and the source for coffee. It is the pit inside the red or purple fruit. This fruit is often referred to as a coffee cherry, and like the cherry, it is a fruit with a pit. Even though the coffee beans are not technically beans, they are referred to as such because of their resemblance to true beans. The fruits most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, called a "peaberry". Peaberries make up only around 10% to 15% of all coffee beans. It is a fairly common belief that they have more flavour than normal coffee beans. Like Brazil nuts and white rice, coffee beans consist mostly of endosperm.
Iced coffee is a coffee beverage served cold. It may be prepared either by brewing coffee normally and then serving it over ice or in cold milk or by brewing the coffee cold. In hot brewing, sweeteners and flavoring may be added before cooling, as they dissolve faster. Iced coffee can also be sweetened with pre-dissolved sugar in water.
Kegerator, a portmanteau of the words keg and refrigerator, is a refrigerator that has been designed or altered to store and dispense from kegs.
White coffee can refer to any of a number of different kinds of coffees or coffee substitutes worldwide.
Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.
Stumptown Coffee Roasters is a coffee roaster and retailer based in Portland, Oregon, United States. The chain's flagship café and roastery opened in 1999. Three other cafes, a roastery and a tasting annex have since opened in Portland, as well as locations in Seattle, New York, and Los Angeles,. Stumptown is owned by Peet's Coffee, which in turn is owned by JAB Holding Company. The company was an early innovator with cold brew coffee in nitro cans and have continued to develop other cold brew product innovations.
Coffee preparation is the process of turning coffee beans into liquid coffee. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be roasted, the roasted coffee beans must then be ground, and the ground coffee must then be mixed with hot or cold water for a specific time (brewed), the liquid coffee extraction must be separated from the used grounds, and finally, if desired, the extracted coffee is combined with other elements of the desired beverage, such as sweeteners, dairy products, dairy alternatives, or toppings.
A Cornelius keg is a stainless steel canister (keg) originally used as containers by the soft drink industry. They can be used to store and dispense carbonated or nitrogenated liquids. Cornelius kegs were originally made by Cornelius, Inc.
RISE Brewing Co., is a New York and Oregon-based nitro cold brew coffee company specializing in nitrogen-infused organic coffee and sourcing Fair Trade organic beans from Peru's Chanchamayo Valley. It uses a proprietary reverse-osmosis spring water filtration process.
Nitro Pepsi is a cola soft drink produced by PepsiCo. It is a nitrogen-infused version of Pepsi. The addition of nitrogen gas, instead of the usual carbon dioxide, creates a smooth texture. It was developed around 2019, and has been marketed since March 2022. The drink comes in an aluminum can containing a widget that infuses the drink with nitrogen when the can is opened, similar to a system developed in the late 1950s by Michael Edward Ash for nitrogenating canned draft beers like Guinness. The beverage is also available in a vanilla flavor.
