Common coffee-term questions

What is third-wave coffee?

Third-wave coffee treats coffee as a craft product like wine or single-malt whisky — single-origin sourcing, roast profiles tuned to highlight a specific bean's flavor, and brewing methods that prioritize clarity over speed. In Brooklyn, third-wave is the dominant style at shops like Sey Coffee, Devoción, and Partners Coffee.

What's the difference between a latte and a flat white?

A flat white is smaller (typically 5–6 oz vs 8–12 oz for a latte), uses less steamed milk with thinner microfoam, and is more espresso-forward. A latte has more milk, a thicker layer of foam on top, and a milder coffee flavor. Both use the same espresso shot underneath.

What's the difference between cold brew and iced coffee?

Cold brew is steeped in cold water for 12–24 hours, producing a smooth, low-acid concentrate that's then diluted to drink. Iced coffee is brewed hot (drip or espresso) and then chilled or poured over ice — brighter, more acidic, and typically more caffeinated per ounce.

What is single-origin coffee?

Single-origin means the beans come from one identifiable source — a single farm, cooperative, or growing region — rather than a blend. It's the standard at specialty shops because it lets the bean's terroir come through; expect to see country, region, farm, varietal, and process printed on the bag.

What's the difference between a cortado and a macchiato?

A cortado is equal parts espresso and steamed milk (~4 oz total) with no foam — a Spanish-Portuguese drink popular at specialty bars. A macchiato is an espresso shot "marked" with a small dollop of foamed milk on top (~2 oz). The cortado is bigger and milkier; the macchiato is more espresso-forward.

What is direct trade coffee?

Direct trade describes a sourcing relationship where the roaster buys green coffee directly from a specific farm or cooperative, paying above commodity price and (ideally) visiting the origin. Unlike Fair Trade, it's not a certification — it's a self-described practice that varies by roaster.

What does "specialty coffee" actually mean?

Specialty coffee refers to beans that score 80+ on the Specialty Coffee Association's 100-point cupping scale. Practically, it signals careful sourcing, traceable origin, fresh roasting, and skilled preparation. Most third-wave shops in Brooklyn serve specialty coffee by definition.

What is a Yemeni coffee house?

Yemeni coffee houses are a fast-growing format in NYC and Brooklyn — late-night cafes serving traditional Yemeni preparations (mofawar, qishr, jubani) alongside dates, sweets, and family-style hospitality. Williamsburg has a particularly strong cluster around the Brooklyn Bridge end. Open hours often stretch past midnight.

What is a long black?

A long black is an Australian/New Zealand drink made by pouring two espresso shots over a small amount of hot water (typically 4–5 oz total). It is similar to an Americano but reverses the order of pour — espresso last — which preserves the crema on top and yields a more espresso-forward cup. Order it when you want black coffee with espresso clarity rather than dilution.

What's the difference between cold brew and nitro cold brew?

Nitro cold brew is regular cold brew that has been infused with nitrogen gas as it pours from a tap, producing a creamy, beer-like cascade and a velvety mouthfeel. The coffee is the same; the texture is the difference. Nitro is poured from a pressurized keg, never over ice, and often drinks like a stout — most Brooklyn specialty shops with cold-brew programs offer both.

What is the bloom in pour-over coffee?

The bloom is the first small pour of water onto fresh coffee grounds — typically twice the weight of the dry coffee — that lets trapped CO₂ escape before the main brew. It is held for 30–45 seconds while the bed swells and bubbles. Skipping the bloom traps gas in the puck and produces a sour, under-extracted cup, which is why every barista-led pour-over starts with one.

What does ratio mean in coffee brewing?

Ratio is the proportion of dry coffee to water by weight, written as 1:N. For pour-over and drip, 1:15 to 1:18 is the specialty norm — 1:15 is stronger and heavier-bodied, 1:18 is cleaner and more delicate. Espresso uses much tighter ratios (1:2 is a standard "modern" shot). Once you measure to a ratio, day-to-day shot consistency becomes a matter of grind and time, not guesswork.

What is washed (or wet) process coffee?

Washed-process coffee is depulped at the mill, fermented in tanks of water for 12–48 hours to remove the mucilage, then washed clean and dried. The result is a cup with bright acidity, transparent origin character, and very little fruit-fermented sweetness — the classic "clean" specialty profile. Most Latin American coffees on a Brooklyn menu are washed; most fruit-forward Ethiopian lots are washed or natural depending on the lot.

What's the difference between a microlot and single-origin?

Single-origin means the beans come from one country, region, cooperative, or farm — a broad term. A microlot is a much narrower slice: a small, separately processed parcel from a single farm, sometimes from one varietal or one specific harvest day. Every microlot is single-origin, but most single-origin coffees are not microlots. Microlots are typically the highest-graded, highest-priced offerings on a roaster's shelf.

What's the origin of the flat white?

The flat white emerged in Australia and New Zealand in the 1980s — both countries claim invention, with strong cases pointed at Sydney and Auckland cafés around 1985. It spread internationally through the 2000s and became a signature drink of third-wave bars in London, then New York, in the 2010s. By the time Brooklyn's specialty boom hit, the flat white was already a default order alongside the cortado.

What is a barista?

A barista is the trained coffee professional who runs the espresso bar — pulling shots, dialing in grinders, steaming milk, and reading the room. The word is Italian for "bartender" and originally referred to anyone working a bar, alcohol included; in American specialty coffee it has narrowed to mean specifically a coffee professional. A skilled barista adjusts grind and dose throughout the day as humidity and bean age shift.

What is "third place" in coffee culture?

Third place is sociologist Ray Oldenburg's term for a community-anchor space that is neither home (first place) nor work (second place) — a café, pub, or barbershop where neighbors bump into each other and informal public life happens. The Brooklyn coffee shop has become a defining example: a place to work for a few hours, take a meeting, or sit and read alongside neighbors. The Friend lane on this guide highlights shops that lean hardest into this role.

What is a Q grader?

A Q grader is a Coffee Quality Institute–licensed cupper certified to score green coffee on the Specialty Coffee Association's 100-point scale. Certification requires passing 22 sensory and calibration exams over a roughly six-day course, and licenses must be renewed every three years. When a coffee is described as scoring 86 or 88, that score was assigned by Q graders cupping the lot under standardized protocols.

What is anaerobic fermentation in coffee?

Anaerobic fermentation is a processing method where coffee cherries are sealed in oxygen-free tanks (often with a one-way valve to release CO₂) for one to several days before drying. The lack of oxygen shifts which microbes drive fermentation, producing wild, fruit-forward, sometimes boozy or funky flavors that don't appear in conventionally washed or natural lots. It is one of the more experimental processing styles you'll see called out on a third-wave Brooklyn menu card.
