A Barista’s Glossary: What the People Behind the Counter Actually Mean

I walked into a third-wave cafe in 2014 and asked for “a tall coffee.” The barista, who was 22 and had the air of a person who had heard many things, looked at me and said: “Pour-over, drip, or cold brew?” I had to ask what the difference was. He was patient. The whole interaction took about 90 seconds. I left with a 6 oz ceramic cup of Ethiopian Yirgacheffe, served black, brewed to order, and a small piece of my dignity left behind on the counter.

The cafe terminology has not gotten less specific in the decade since. If you want to order coffee without feeling like you’re decoding a foreign language, here’s the working glossary of the terms baristas actually use. I’m focusing here on the worker-side jargon (the things a barista says to other baristas, or to you when assuming you know what they mean) more than the drink names themselves. For drink names, see our coffee drinks glossary.

Extraction terms

Pull (a shot). The act of extracting an espresso. “I’ll pull you a doppio.” The word comes from the lever-operated espresso machines of the 1940s, where the barista physically pulled a spring-loaded lever to force water through the puck.

Dose. The amount of ground coffee used in an espresso basket, measured in grams. A standard double shot dose is 16-20 grams of coffee. “What dose are you using?” is a question about the espresso recipe.

Yield. The weight of espresso extracted from a given dose. A standard ratio is 1:2, meaning 18 g of coffee in produces 36 g of espresso out. “Ratio” is sometimes used interchangeably.

Pull time. How long the shot took to extract, typically 25-32 seconds for a properly dialed-in espresso. A 15-second shot is “running fast” (under-extracted); a 45-second shot is “running slow” (over-extracted).

Dialing in. Adjusting grind size, dose, and yield to optimize a coffee for the current conditions (humidity, bean age, machine state). Baristas dial in a new bag of coffee at the start of every shift.

Channeling. A flaw where water finds the path of least resistance through the espresso puck, extracting unevenly. Visible as a sour, thin, off-tasting shot, often with a hollow center in the puck after extraction.

Crema. The reddish-brown foam on top of a properly pulled espresso shot. Made of CO2, emulsified oils, and dissolved compounds. Disappears within 2 minutes after pulling, which is why espresso should be drunk fresh.

Puck. The compressed disc of spent coffee grounds in the portafilter after a shot. Knocking the puck into the knock-box is the universal “shot done” signal.

Equipment terms

Portafilter. The handled device that holds the coffee basket and locks into the espresso machine group head.

Group head. The brewing nozzle on an espresso machine where the portafilter locks in and water is forced through.

Basket. The metal filter that holds the ground coffee inside the portafilter. Comes in single (7-12 g), double (14-20 g), and triple (21+ g) sizes.

Tamper. The small handheld tool used to press ground coffee into the basket. Tamping creates the even bed of grounds that allows uniform water flow.

Distribution tool. An optional puck-prep tool that helps spread coffee grounds evenly in the basket before tamping. Reduces channeling.

Steam wand. The metal tube on an espresso machine that injects steam into milk to heat and texture it. The skill of using a steam wand correctly takes months to develop.

Knock-box. The container under the espresso machine for discarding spent pucks. Has a rubber-padded knock bar.

Grinder hopper. The reservoir on top of a coffee grinder that holds beans. Most cafes keep two or three hoppers loaded with different coffees.

Milk and texturing terms

Microfoam. Milk steamed to produce small, uniform bubbles that integrate fully with the milk, creating a glossy paint-like texture. The basis for latte art and the proper mouthfeel of a flat white.

Stretching. The first phase of steaming milk, where air is incorporated to increase volume. Followed by the texturing phase, where the bubbles are broken down into microfoam.

Texturing. Spinning the milk in the pitcher with the steam wand to break large bubbles into microfoam.

Pour. Combining milk and espresso in the cup. Different drinks have different pour techniques (a latte pour vs. a cappuccino pour vs. a flat white pour).

Latte art. Decorative patterns drawn on the surface of an espresso milk drink using free-pour or etch techniques. Common forms: rosetta, tulip, heart, swan.

Coffee quality terms

Cupping. The formal coffee-tasting process used by roasters and buyers to evaluate beans. The taster grinds the coffee, adds hot water in a cupping bowl, breaks the crust with a spoon, smells, slurps loudly, scores on standardized criteria.

Specialty coffee. A formal designation for coffee scoring 80 or above on the Specialty Coffee Association’s 100-point scale. About 15% of global coffee qualifies as specialty.

Single origin. Coffee from a single farm, region, or country, kept separate rather than blended. Allows the unique flavor character of a place to come through.

Blend. Coffee from multiple origins combined intentionally by a roaster, usually for consistency and a particular flavor profile.

Roast level. How dark a coffee has been roasted. Common names: cinnamon, light, medium, medium-dark (Full City), dark (Vienna), very dark (French), burnt (Italian).

First crack, second crack. Audible cracking sounds during roasting that mark transitions between roast levels. Light roasts stop after first crack; dark roasts continue through and after second crack.

Acidity. The brightness or sharpness in a coffee’s flavor, similar to wine acidity. Not the same as pH-acid; describes a tasting characteristic.

Body. The weight or fullness of the coffee on the palate. Light body is tea-like; full body is heavy and substantial.

Finish. The lingering taste after swallowing, similar to wine finish. A “long finish” describes flavors that persist for many seconds after the sip.

Useful terms when ordering

Wet vs. dry. For cappuccinos. “Dry” means more foam, less steamed milk. “Wet” means more steamed milk, less foam.

Solo, doppio. Single and double shot of espresso, respectively.

For here vs. to go. Self-explanatory but useful: “for here” gets you a ceramic cup; “to go” gets you a paper cup with a lid.

Light, dark, blonde. Roast level requests. “Blonde” specifically refers to a very light roast.

One sugar, no sugar, sugar on the side. Communicating sweetener preferences. Speciality cafes don’t usually pre-sweeten; chains often will.

The actual bottom line

Most good baristas don’t expect you to know any of this. The 22-year-old in Greenpoint who took my order in 2014 was patient because most of his customers didn’t know what they wanted either. The vocabulary exists to be specific between professionals; you don’t have to use it to be served well.

If you want to be useful at the counter, the single most helpful phrase is: “What would you recommend for someone who likes [thing]?” Filling in [thing] with “strong coffee,” “less bitter,” “something fruity,” or “Vietnamese coffee” gives the barista something to work with. The terminology in this glossary is for the moments when you’re curious why your coffee tastes a certain way, or when you’ve started making coffee at home and want to understand what the YouTube barista is talking about.
