Bar Terms, Slang & Bartending Basics

Next, Smirnoff will probably be the call vodka, then Absolut for a premium vodka, and Ketel One for ultra-premium vodka. (Just so you know, there wasn't an ultra-premium category until the Chopin and Grey Goose type boutique vodkas hit the market in the late 1990s.)

Large-format ice — big cubes or spheres — melts more slowly than standard ice, diluting a drink less over time. It became a signature look and function of the craft cocktail bar movement.

What does "N/A" mean on a modern cocktail menu?
Non-alcoholic. The zero-proof and "sober curious" movement grew rapidly through the 2010s and especially after 2020, and most craft bars now dedicate real menu space to N/A cocktails rather than treating them as an afterthought.

What is a "dealcoholized" spirit or wine?

What is a "regulars" app or loyalty program at a bar?
Digital point-of-sale-linked loyalty systems (common by the mid-2010s) that track a guest's visits and drink preferences, sometimes offering perks after a certain number of visits — a tech-driven evolution of the old-fashioned bartender who "just remembers."

What changed about tipping at bars with the rise of mobile POS systems?
Handheld and tablet-based point-of-sale systems (which became standard through the 2010s) introduced suggested tip percentages directly on the payment screen, changing tipping behavior and often increasing average tip amounts compared to a blank tip line.

​

What does "cocktails-to-go" mean, and how did the law change?
Selling sealed, pre-mixed cocktails for off-premise consumption — something most states banned before 2020.

What does "nitro" mean when applied to a bar drink?

What does it mean for a bar to run a "zero-waste" or "root-to-stem" program?
Using as much of an ingredient as possible — citrus husks, herb stems, fruit scraps — instead of throwing them away, often turning them into syrups, garnishes, or infused spirits. This sustainability-focused approach to bartending gained real traction in the craft cocktail world during the 2010s.

The rise of Instagram and other visual social media platforms pushed many bars to design cocktails specifically to photograph well — dramatic garnishes, smoke, colored ice, and elaborate glassware became a real marketing strategy, not just decoration.

What is a "speakeasy-style" bar today, as opposed to a real Prohibition-era speakeasy?
A modern bar designed to evoke the hidden, password-required feel of a real speakeasy — often behind an unmarked door, inside a phone booth, or through a secret entrance — purely as an aesthetic and experiential choice, not out of actual legal necessity. This became a widespread trend across major U.S. cities in the 2010s.

What does "low-ABV" or "session cocktail" mean?

​

What is an "RTD" cocktail?
Ready-to-drink — a pre-made, canned or bottled cocktail sold at the same alcohol strength as one made behind a bar, as opposed to a lower-ABV hard seltzer. Cutwater Spirits helped pioneer the single-serve canned format in the mid-2010s and was acquired by Anheuser-Busch in 2019; High Noon, launched the same year, quickly became one of the category's top sellers. RTD sales accelerated even further during the pandemic, when people were mixing cocktails at home more than ever.

How is an RTD cocktail different from a hard seltzer?
A hard seltzer is typically a malt- or sugar-fermented base with added flavoring and relatively low alcohol content. An RTD spirits-based cocktail actually contains real distilled spirits — vodka, tequila, whiskey — mixed to standard cocktail strength, then canned.

What is a "dealcoholized" spirit? (see earlier N/A entry)

What does "contactless payment" mean at a bar, and when did it become standard?

What is a QR code menu, and why did bars start using them?
A scannable code that pulls up a bar's drink menu on a guest's own phone instead of a printed menu.

What is "flash pasteurization," and why do some bars use it on house-made juices?
Briefly heating a juice or syrup to a specific temperature to kill bacteria without cooking the flavor out, extending its shelf life. As craft bars built larger house-made juice and syrup programs through the 2010s, flash pasteurization became a practical food-safety tool for keeping those ingredients fresh longer.

What is a "dry bar" or "sober bar"?
A bar that serves no alcohol at all, built around mocktails, N/A spirits, and the same social atmosphere as a traditional bar. These venues began opening as standalone concepts in the late 2010s as the sober-curious movement grew, offering people a place to go out without alcohol being the point.

What does "better-for-you" mean when applied to alcohol marketing?
A marketing category built around lower calories, lower sugar, or "cleaner" ingredient lists — a direct response to health-conscious consumer trends that grew significantly through the 2010s and into the 2020s, influencing everything from hard seltzers to spirits themselves.

​

When did "zero-proof" become a common term, and what does it mean?

What does "fat-washing" mean, and why do bartenders do it?
Infusing a spirit with the flavor and texture of a fat or oil — bacon grease, browned butter, sesame oil, duck fat, peanut butter — then freezing and straining the fat back out. It became a popular craft cocktail technique for adding rich, savory depth to a spirit without leaving any actual fat behind.
