An alcopop (or cooler) is a category of mixed alcoholic beverages with relatively low alcohol content (e.g., 3–7% alcohol by volume), including:

The term alcopop (a portmanteau of the words alcohol and pop) is used commonly in the United Kingdom and Ireland to describe these drinks. In English-speaking Canada, "cooler" is more common but "alcopop" may also be used. Other terms include flavored alcoholic beverage (FAB), flavored malt beverage (FMB), "pre-packaged" or "premium packaged" spirit (PPS). In Australia and New Zealand "premix" and ready to drink (RTD) are both commonly used terms. "Spirit cooler" is used in South Africa for distilled alcohol versions.

Hard seltzer is a related category of alcoholic drinks based on flavored seltzer water. Hard soda, meanwhile, is specifically related to soft drinks. Hard lemonade, which could be considered an alcopop, has been around for some time. Hard cider, on the other hand, is a fermented beverage similar to wine or beer.

There are a variety of beverages produced and marketed around the world as well as within each market which are described as coolers or alcopops. They tend to be sweet and served in small bottles (typically 355 ml (the normal size of a soda pop can) in the US, 275 ml in South Africa and Germany, 330 ml in Canada and Europe), and between 4% and 7% ABV. In Europe, Canada, and South Africa coolers tend to be pre-mixed spirits, including vodka (e.g. Smirnoff Ice) or rum (e.g. Bacardi Breezer). In the United States, on the other hand, alcopops often start out as un-hopped beers, depending on the state in which they are sold. Much of the malt (and alcohol) is removed (leaving mostly water), with subsequent addition of alcohol (usually vodka or grain alcohol), sugar, coloring and flavoring. Such drinks are legally classified as beers in virtually all states and can therefore be sold in outlets that do not or cannot carry spirit-based drinks. There are, however, stronger ones that are simply pre-mixed spirits (e.g. Bacardi Rum Island Iced Tea), often containing about 12.5% alcohol by volume, that can be sold only where hard liquor is available.^{[citation needed]}

Wine coolers gained popularity in the US market in the 1980s when Bartles and Jaymes began advertising their brand of wine coolers, which were followed by other brands, including when Bacardi introduced the Breezer. A growth in popularity occurred around 1993 with Two Dogs, DNA Alcoholic Spring Water, Hooper's Hooch and Zima, which was marketed under the title of "malternative beverage." Wine coolers were on the decline due to the increase in the US federal wine tax, and using a malt-beverage base became the new industry standard. Later, Mike's Hard Lemonade was released in the United States, with humorous commercials depicting what they called "violence against lemons". Smirnoff also came out with another citrus-flavored malt beverage in the United States in the late 1990s called Smirnoff Ice, which promoted itself with flashy commercials, usually involving trendy young people dancing in unlikely situations and places. (In the UK, Smirnoff Ice is marketed by Diageo as a PPS.)

Through its Alcopop-Free Zone® campaign, " Alcohol Justice has sought to ban alcopop sales entirely since the sweet and brightly colored alcoholic drinks may appeal to children. Many cooler advertising campaigns have been criticized as trying to make alcopops appeal to young drinkers. In the United Kingdom, a media outcry during the mid-1990s arose as the tabloid press associated alcopops with under-age drinking which damaged sales and led to British liquor stores withdrawing them from their shelves.

In response to a complaint from the Center for Science in the Public Interest (CSPI), the Federal Trade Commission (FTC) conducted an extensive investigation in 2001. The agency "found no evidence of intent to target minors with FMB products, packaging, or advertising. Furthermore, after reviewing the consumer survey evidence submitted by CSPI in support of the proposition that FMBs were predominantly popular with minors, the FTC concluded that flaws in the survey's methodology limited the ability to draw conclusions from the survey data."

The Federal Trade Commission again in 2003 investigated FMB ads, product placement, and internal company marketing documents after a directive from the conferees of the House and Senate Appropriations Committees. "The Commission's investigation found no evidence of targeting underage consumers in the marketing of FMBs. Adults 21 to 29 appear to be the intended target of FMB marketing" and found that "the majority of FMB drinkers are over the age of 27."
