Cold Brew

The right grind size depends on your brewing method. Espresso requires an ultra-fine grind (similar to powdered sugar), pour over and drip use medium-fine to medium, French press and cold brew use coarse to extra-coarse, and AeroPress adjusts based on your brew time. Use the chart below to find your starting point, then adjust based on taste. This guide covers the correct grind size for every major home brewing method, what happens when you go too fine or too coarse, and how to dial in your grinder without wasting coffee. ...

Nitro cold brew is cold brew coffee infused with pressurized nitrogen gas. The nitrogen creates millions of tiny bubbles, giving the coffee a smooth, creamy texture and a cascading pour — similar to a Guinness stout — all without ice, milk, or sweetener. It tastes naturally sweeter than regular cold brew because nitrogen suppresses perceived bitterness, and the velvety mouthfeel makes it feel almost like drinking coffee through cream. At Starbucks, nitro cold brew contains 280mg of caffeine in a Grande — one of the highest-caffeine drinks on the menu. ...

Cold foam is frothed cold milk — light, airy, and non-fat. Whipped cream is heavy cream beaten with air until thick and rich. The key difference: cold foam is made from skim milk (0% fat), which creates a stable foam that floats on cold drinks. Whipped cream is 35–40% butterfat — it’s dense, sweet, and melts quickly into hot or iced drinks. At Starbucks, the cold foam distinction created the “cold foam” drink category starting in 2018. At home, the choice between the two depends on your drink, your equipment, and what you’re going for: a barista-style float, or a dessert-style topping. ...

Espresso and cold brew are opposites in almost every way — one uses high heat and pressure for a 30-second extraction, the other uses cold water and time for a 12–24 hour steep. The result is two very different beverages that serve different needs. Here’s a direct comparison across every meaningful variable. Espresso vs Cold Brew at a Glance Espresso Cold Brew Water temperature 90–96°C (194–205°F) Cold or room temp (~20°C) Pressure 9 bar None Extraction time 25–30 seconds 12–24 hours Yield 30ml per shot 500–1,000ml concentrate Serving size 30ml (single) or 60ml (double) 120–360ml (diluted) Caffeine per serving 60–75mg (single) 150–300mg (12oz diluted) Acidity Higher (pH ~5.5–6.0) Lower (pH ~6.3) Flavor Bold, concentrated, complex Smooth, sweet, low-acid Bitterness Present, balanced Low Equipment needed Espresso machine Mason jar or pitcher Prep time 2–3 minutes 12–24 hours Cost per serving (home) $0.30–0.80 $0.15–0.50 Caffeine: Which Has More? This is the most common question — and the answer depends on whether you’re comparing per-ounce or per-serving. ...

Pumpkin cream cold brew is cold brew coffee sweetened with pumpkin spice syrup and topped with pumpkin-flavored cream cold foam. At Starbucks it’s a seasonal menu item — at home, you can make it year-round in 10 minutes. The two-layer presentation — dark cold brew below, pale orange pumpkin cream on top — is visually striking and functionally smart: the unsweetened cold brew provides the coffee base, while the sweet, spiced cream delivers the pumpkin flavor without overwhelming the coffee. ...

Cold brew typically contains 150–300 mg of caffeine per 12 oz serving — often more than the same volume of hot drip coffee (150–200 mg). The key variable is whether you’re drinking straight cold brew concentrate (higher) or a diluted ready-to-drink version (comparable to drip). The range is wide because cold brew caffeine depends on three things: the coffee-to-water ratio used during steeping, whether you dilute the concentrate before drinking, and the caffeine content of the specific beans. Here is how to understand exactly what is in your cup. ...

Cold brew coffee is made by steeping coarsely ground coffee in cold or room-temperature water for 12–24 hours — no heat, no brewing machine. The result is a smooth, low-acid coffee concentrate that is diluted and served cold. Cold brew is not iced coffee: the two are made completely differently and taste very different. How Cold Brew Is Made The cold brew process has four steps: Coarse grind — Coffee is ground coarsely, similar to French press. Fine grinds over-extract and turn bitter in cold water. Cold water steep — Grounds are submerged in cold or room-temperature water. The standard ratio is 1:8 (1g coffee per 8g water) for regular strength, or 1:4 for concentrate. Long steep — The mixture steeps in the refrigerator (or at room temperature) for 12–24 hours. Cold steeping is slower than hot brewing, which is why it needs much more time. Filter — The grounds are filtered out through a fine mesh strainer, cheesecloth, or paper filter. What remains is smooth cold brew concentrate or ready-to-drink cold brew. There is no heating involved at any stage. This is the defining characteristic that separates cold brew from every other brewing method. ...

Cold brew coffee is coffee made by steeping coarsely ground coffee in cold or room-temperature water for 12–24 hours, then straining out the grounds. No heat is used at any point. The result is a smooth, low-acid coffee concentrate that is typically diluted before drinking. Cold brew is not iced coffee (which is hot-brewed coffee poured over ice). The cold-water extraction process produces a chemically different beverage with a distinctly smoother, sweeter, and less bitter taste. ...

Vietnamese egg coffee (cà phê trứng) is a Hanoi speciality made by whipping egg yolk with sweetened condensed milk into a thick, custard-like cream, then spooning it over a small, intensely strong cup of Vietnamese coffee. The result is rich, sweet, and unlike any other coffee drink — a dessert and a coffee in one cup. Vietnamese Egg Coffee at a Glance Vietnamese name Cà phê trứng Origin Hanoi, Vietnam (1940s) Base coffee Strong drip (Robusta), espresso, or Moka pot Egg component Whipped egg yolk + sweetened condensed milk Flavor Rich, custardy, sweet, intensely caffeinated Served Hot (cup in hot water) or iced Caffeine High (strong coffee base) Why Egg in Coffee? The Origin Story Egg coffee was invented at Giảng Café in Hanoi in the 1940s during French colonization. During the wartime years, fresh milk became scarce and expensive. Nguyễn Văn Giảng, a bartender at the Sofitel Metropole Hotel, used whipped egg yolk and sweetened condensed milk as a substitute — and accidentally created one of the most distinctive coffee drinks in the world. ...

Cold brew is never heated — coffee grounds steep in cold water for 12–24 hours, producing a smooth, low-acid concentrate. Iced coffee is hot-brewed coffee poured over ice, which is faster (minutes vs. hours) but results in a thinner, more acidic drink. Both are delicious. But they taste different, cost different amounts of effort, and hit different notes. Here’s exactly how they compare. Cold Brew vs Iced Coffee at a Glance Cold Brew Iced Coffee Brew method Steep in cold water 12–24h Hot brew, then cool Time to make 12–24 hours 5–10 minutes Flavor Smooth, chocolatey, low-acid Bright, slightly bitter, more acidic Caffeine Higher (concentrate) Standard (depends on dilution) Acidity Low (pH ~6.3) Higher (pH ~5.0–5.5) Cost Lower per serving (DIY) Very low, very fast Shelf life 1–2 weeks refrigerated Same day Best for Sensitive stomachs, smooth sipping Quick prep, bright flavor, classic iced What Is Cold Brew? Cold brew coffee is made by steeping coarse-ground coffee in cold or room-temperature water for an extended period — typically 12 to 24 hours. No heat is ever applied. ...
