Iced coffee

Iced coffee is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Iced coffee rather than just read about it. In short: Iced coffee is coffee served cold. It may be prepared either by brewing coffee normally (i.e. carafe, French press, etc.) and then serving it over ice or with cold milk, or by brewing the coffee cold.

Key takeaways

  • Iced coffee belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Iced coffee to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Iced coffee from memory before moving on to harder problems.

Reference excerpt

Iced coffee is coffee served cold. It may be prepared either by brewing coffee normally (i.e. carafe, French press, etc.) and then serving it over ice or with 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. Iced coffee is regularly available in most coffee shops. Iced coffee is generally brewed at a higher strength than normal coffee, to compensate for dilution by melting ice. Iced coffee is made by brewing hot coffee, and pouring it over ice; cold brew coffee is made without heat by steeping coffee grounds into lukewarm water. In Australia, packaged iced coffee with milk and sweetener is widely distributed.

History Mazagran, a cold, sweetened coffee beverage that originated in Algeria around 1840, has been described by locals as "the original iced coffee". It was prepared with coffee syrup and cold water. Frozen coffee beverages, similar to slush, are documented in the 19th century. The Italian granita al caffè is a similar beverage. "Iced coffee"—coffee that has been brewed and then chilled with ice—appeared in menus and recipes in the late 19th century. Iced coffee was popularized by a marketing campaign of the Joint Coffee Trade Publicity Committee of the United States in 1920. Much later, it was marketed by chain outlets, including Burger King, Dunkin' Donuts and Starbucks.

Variations by country

Australia

In Australia, iced coffee may include syrup, cream, cocoa powder or coffee beans. The café style is something like an unblended milkshake, and may be made from espresso coffee or only coffee flavoring. Bushells has marketed a Coffee and Chicory Essence since the late 19th century, as has Bickfords since 1910. There are many brands of packaged iced coffee consisting of coffee, milk, and sweetener. In South Australia, Farmers Union Iced Coffee has outsold Coca-Cola and is one of the state's biggest brands. Pauls "Territory's Own" Iced Coffee is popular in the Northern Territory and Norco Real Iced Coffee is prominent in Northern New South Wales and South East Queensland. Other brands include Breaka, Big M, Brownes Chill, Moove, Masters, Dare, Max, Fleurieu, Rush, Oak and Ice Break.

Canada In Canada, many fast-food and beverage chains sell iced coffee. The popular Tim Hortons coffee chain sells iced cappuccinos known as Iced Capps and recently introduced standard iced coffee to its Canadian menu in addition to its U.S. menu. The popularity of iced coffee drinks increased by about 16 percent between 2015 and 2016.

Chile In Chile, iced coffee is called café helado (iced coffee) and is popular in the summer. Café helado is composed of espresso or coffee powder. Ice cream is added to the coffee, as are sugary additives such as vanilla, cinnamon, or dulce de leche. Iced coffee is served during the summer at breakfast and at parties. Chilean iced coffee may be topped with whipped cream and chopped nuts.

Germany

In Germany, there are different types of Eiskaffee (coffee with ice cream). The most widespread form includes milk and sweeteners, and is served in coffeehouses and in Eisdielen (ice cream parlours). It consists of filtered, hot brewed and cooled coffee with vanilla ice cream and whipped cream on top. In supermarkets, the most common canned version includes flavors such as cappuccino and espresso. This iced coffee is very similar to the canned iced coffee in the UK and in the case of some brands (particularly Nestlé) actually the same product.

Greece

In Greece, the most popular iced coffee beverage is frappé, made of instant coffee (generally Nescafe), water, and optionally, sugar using either an electric mixer or a shaker to create foam. Ice cubes and, optionally, milk are added. Frappés became known outside of Greece as a result of the 2004 Summer Olympics in Athens. Frappés have become very popular in Cyprus and Romania. The second most popular iced coffee beverage in Greece is the freddo cappuccino which is topped with a cold milk foam known as afrógala (Greek: αφρόγαλα) and freddo espresso which is a double shot of espresso blended with ice cubes and served over ice.

Italy

In Italy, the Nestlé company introduced Frappé coffee under its Nescafé Red Cup line, with the name Red Cup Iced Coffee. Many Italian coffee bars serve "caffè freddo", which is straight espresso kept in a freezer and served as icy slush. In the Salento region of Apulia, this was perfected by brewing the espresso freshly, adding the desired amount of sugar or almond milk and finally pouring it into a whiskey glass filled with ice cubes right before being served, known as caffè in ghiaccio, or coffee in ice. Affogato (espresso poured over a scoop of vanilla gelato or ice cream) is also served, typically as a dessert.

Capsule-based coffee systems have expanded to include iced coffee and frappé-style options, as seen in the Nescafé Dolce Gusto Iced Frappé capsules available in Europe.

Japan In Japan, iced coffee (アイスコーヒー, aisu kōhī) has been drunk since the Taishō period (around the 1920s) in coffeehouses. It is served with gum syrup and milk. Cold tea was already popular, so it was natural to drink cold coffee. Cold brew coffee is also common in Japan, where it is known as Dutch coffee (ダッチ・コーヒー, dacchi kōhī), due to the historical Dutch coffee trade from Indonesia. In 1969, UCC Ueshima Coffee released canned coffee, which made coffee available everywhere. Today, canned liquid coffee is consumed both cold and hot. Some Japanese iced coffee is prepared by brewing the coffee with hot water and allowing the coffee to drip over ice cubes. The volume of hot water is reduced to account for the dilution of the coffee by the melting ice. This method produces results similar to other iced coffees but is comparable to brewing hot coffee in time and effort.

New Zealand In New Zealand, iced coffee is popular and served in a number of cafes. It is often served with vanilla ice-cream or whipped cream.

Thailand

Thai iced coffee is brewed using strong black coffee, sweetened with sugar, heavy cream (or half-and-half) and cardamom, and quickly cooled and served over ice. Some variations are brewed using espresso. Thai iced coffee can be served with whipped cream on top for a layered effect and garnished with cinnamon, vanilla or anise. It is a common menu item at Thai restaurants.

Worked examples

Example 1 — a first encounter with Iced coffee

Start with the simplest possible case. Write down what Iced coffee claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Iced coffee before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Iced coffee ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Iced coffee

In research
Iced coffee appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Iced coffee in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Iced coffee is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coffee drinks, Cold drinks, Iced coffee, so understanding it makes those chapters shorter.
In everyday life
Look for Iced coffee outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
